Both parents have brown eyes, which the child will have. What eye color will the child have? What color are the eyes of newborns

When a woman is in a position, parents often think about who the baby will look like, what character traits he will take from dad and mom, with what eye color he will appear in this world. Especially the last question occupies those couples in which the husband and wife have a different shade of eyes.

In order to most likely assume this in advance, there is a table for determining the color of the eyes of a child from the parents. The information it contains is a simple diagram of the likely options based on what kind of eyes each parent has.

At birth, the child most often has a cloudy blue tint to the eyes. This does not mean that such a color will remain with him forever. Usually, by 6 months, children's eyes acquire the color that will remain for life.

Child's eye color probability
75%	18,75%	6,25%
50 %	37,5%	12,5%
50%	0%	50%
	75%	25%
0%	50%	50%
0%	1%	99%

How to understand a child's eye color chart

The table for determining the color of the eyes of a child differs from ordinary tables, because it has few numbers and values. A table with the Rh factor was compiled in a similar way, they are similar to each other. The left column is a combination of pairs of parents' eyes, depicted as color drawings: brown + brown, brown + green, blue + green, etc.

The top line of the table also depicts eyes with the color that a born baby can have: brown, green or blue-gray. And at the intersection of columns and rows, the probability values are indicated as a percentage. Therefore, it is quite easy to understand the sign.

For example, if one parent has blue eyes and the other has brown eyes, there is a 50% chance that the newborn will develop a brown tint as they grow older, and a 50% chance of blue-gray, and the chance of green eyes is 0. %. Similarly, you can understand the information for other options.

Marina, mother of one-year-old Nastya: “My parents and I have dark brown eyes, and my husband has green eyes. Even before the birth of Nastya, we looked at tables for determining the color of the eyes of a child and wondered what color her eyes would be. According to the plate, it turned out that the most likely that her eyes would be a copy of mine. We were very surprised when we saw her dark gray shade, but we realized that we had to wait. All babies are born with this color. And closer to the first half of the year, the true color appeared, which remains to this day. Anastasia has the same green eyes as her dad! He is very proud of this, because the probability was small. ”

Are there exceptions to the rules?

The table for determining the possible eye color in a child is a convenient and useful tool, but genetics has a great sense of humor. One of her most unusual jokes is the situation when a baby is born with eyes of different colors. This feature is called heterochromia, it can be complete or partial. Most people live with healthy eyes all their lives and do not complain about an unusual color, although sometimes such pigmentation causes the development of early cataracts.

Another exception to the rules described in the table is when a child is born with an eye color that was 0% likely to occur. This can be confusing for parents. But if the possibility of other paternity is ruled out, such an exception may be caused by a mutation or malfunction of melanocytes. These cases in medicine are rare, but it is also impossible to exclude this possibility ahead of time.

As Paulo Coelho wrote in one of his books: "The look shows the strength of the soul." Therefore, it does not matter what color the child's eyes will be, it is much more important that he be a strong and happy person.

As a result, the child will have, depends on 90% of genetics and only 10% on the case. The color of the iris is determined by the concentration of melanin (coloring pigment): if it is small, it turns blue, if there is a lot, brown, the rest of the shades are located between these colors.

Melanin protects the eye from exposure to ultraviolet rays; the fat-like substance cholesterol and the amino acid tyrosine are involved in the process of its formation.

Eye color formation

Babies are born with blue or brown eyes, and after 6 months the color may change with exposure to sunlight and genetic factors. Usually, in brown-eyed babies, the color does not change, and the more melanin accumulates, the darker the color of the iris will be.

By the age of 3-4, the baby's eyes acquire a permanent color that remains for life.

You can see other options in which eye color changes.

It is impossible to predict for sure what eye color the baby will have: each child has one version of the same gene: maternal and paternal (these genes are called alleles). One of them will be dominant (predominant), the other recessive.

For example, if the mother Blue eyes, and dad has light green, the child will have the following probability: 60% - the eyes will be blue (since the blue tint is dominant), 40% - light green.

Eye color can be passed down through generations(from grandparents), not only color is also inherited, but also blotches on the iris.

The shade of eye color is influenced by other genes that are responsible for skin tone and hair color. For example, blond people with fair skin are characterized by light shades, blue eyes are typical.

For representatives of the Negroid race - people with dark skin, dark hair - brown eyes are characteristic.

The gene responsible for coloring the iris in blue or brown is located on chromosome 15; gene that carries information about green and blue color- on chromosome 19. The pigment of the iris of the embryo is formed already at the 10th week of gestation.

Eye color also depends on the following factors:

Distribution of melanin pigment in the posterior (ectodermal, outer) and anterior (mesodermal, inner) layer of the iris;
The density of the fibers of the iris.

Eye color can change in bright light or extreme cold.

In children, the shade may darken and become cloudy after waking up, crying; this phenomenon is called a "chameleon".

Possible options

Eyes can have the following colors:

Heterochromia

Heterochromia (multi-colored eyes) is a condition in which the eyes differ in color, or different colors are present on the iris (partial heterochromia).

This feature is individual and natural.- a kind of game of nature, - but it can also indicate some ophthalmic diseases (disseminated melanoma, inflammation of the iris), so it is important to periodically be examined by an ophthalmologist.

It is difficult to predict what eye color a baby will have, since modern science has not fully studied the ongoing processes.

Even the most experienced geneticist will not be able to predict with 100% certainty the shade of the iris, not only because there are a number of reasons that can change color, but also because there are exceptions to the rules.

It is impossible to make a mistake, only if both parents have blue eyes: the baby will definitely be born blue-eyed.

Parents are very excited about the birth of their baby and have already visually imagined what their baby will be like. Someone dreams of a fair-haired blue-eyed girl, and someone of a swarthy and dark boy with brown eyes.

However, nature decreed otherwise and a child is born who did not adopt the color of the eyes from his parents, as they would like. Why does this happen?

Again, in this case, everything has its explanation at the genetic level. It must be understood that the genes of close relatives in the family can play a big role and affect the change in eye color.

For example, a baby with blue eyes is born to brown-eyed parents. This may be. For example, a dark-skinned child is born to fair-skinned parents. If you remember relatives, it is possible that one of the parents would have a black grandfather or grandmother. This explains everything.

Child's eye color: table and main varieties

The teaching of genetics, which is included in the course of biology, in addition to determining the type of face and other physical properties child, considers the factors that affect the tone of the irises. This theory suggests several options for formation. There are two main genes that form the color of the eyes of a child from parents, a table of varieties of which will help predict the future shade - these are genes located on chromosomes 15 and 19.

genes for coloration

Gene 15 chromosome. To determine what eye color a child will have, the table should include the main tones and shades. The fifteenth gene creates a brown or blue color. The dominant tone here is brown. A brown-eyed woman and a blue-eyed (green-eyed) man will have brown-eyed children, and their grandchildren will have unpredictable coloration.

Gene 19 chromosome creates green or blue (gray, blue) colors. The green tone is dominant here, but if at least one brown 15th gene is present, then, regardless of the presence of the 19th gene, the iris will be brown. Two green 19th genes, as well as blue plus green, create a green tone, and two blue genes create a blue tone. To make it easier to understand how to determine the color of the eyes of an unborn child, the table should be viewed horizontally.

Green tint that includes the eye color chart

In babies with green eyes, the iris usually has brown speckles or a predominance of swamp color. Completely green eyes in newborns are almost never observed. This tone, regardless of shade, is due to the low content of melanin. The presence of the pigment lipofuscin also affects the green color of the irises.

Gray and blue color

The corresponding eye color of a child from parents, which is displayed in the table, is explained by the density of the shell: the tissues of the outer layers, the denser, the lighter the tone. The highest density of fibers is observed with light gray irises. Gray coloration, like blue, is more characteristic of Europeans. To reveal the color of the child's eyes, the table is considered the most visual way.

Blue colour

This color is obtained as a result of the content of the corresponding pigment in the outer layers. The low density of the outer layer gives a light color, and vice versa. To determine what eye color a child will have, the table is the most convenient option. Moreover, there are no blue fibers in the iris - the light, falling on the surface, is scattered, and only part of the rays absorbs the inner layer filled with melanin. Thus, with the combination of all these factors, we observe the tone of the eyes of babies, in this case - the blue iris.

Child's brown eye color: table

These tones are considered the most common - this is due to the fact that a high number of melanin pigment is present in the iris. In addition, the gene containing information about brown or black color is dominant. To determine the tone will help the table of eye colors of the unborn child. In babies, black color is more often observed in Asian countries.

What kind of eyes will the child have?

The most common question that future parents have is - with what eyes will the baby be born? Many dream of a blue-eyed girl, and someone of a brown-eyed boy.

In order to determine what the color of the eyes will be, you can use a special definition table.

As can be seen from the table, if both parents have the same eye color, then the probability approaches 99% that the baby will have exactly the same eyes.

Of course, this table is close to ideal, but we must remember that nature also has its gifts and surprises. Sometimes, the parents of the baby expect one thing, but in reality a baby is born with a completely different eye color.

How to understand the table for calculating eye color in a child?

How to understand the table and use it without doubt?

Let's take a closer look:

The first situation when both parents have brown eyes, then in this case there is a 75% chance that the baby will be born with brown eyes, 18.75% that the baby will be born with green eyes and 6.25% of blue eyes.
The second situation is when one parent has brown eyes and the other has green eyes. In this case, a child of 50% can be born with brown eyes, 37.5% with green and 12.5% with blue.
The third situation is when one parent has brown eyes and the other is blue, then there is a 50% chance that the baby will have brown eyes, 0% green eyes, and 50% blue eyes.
The fourth situation, when both parents with green eyes, then the probability of green eyes reaches 75%, and blue 25%.
The fifth situation is when partners have blue and green eyes. With this mixing, there is a 99% chance that the child adopts blue eyes from the parents, as well as a 1% chance of green eyes.

As you can see, everything is quite logical and there is an explanation for everything. It is worth adhering to that opinion, then the probability of adopting one or another eye color depends on the color of the partners' eyes. Therefore, difficulties with determining the color of the eyes cannot arise.

However, you should always remember that there are exceptions to the rules and often, even if there is a 0% probability of the formation of any eye color, it is possible that the baby will have such an eye color.

It is necessary to take into account genetics, which cannot be altered, and even more so to influence. All the same, the processes carried out at the genetic level have a certain power, and even more so, it is impossible for anyone to influence such processes.

Of course, when crossing genes, different options are possible, both the most obvious and the most unexpected for the baby's parents.

Therefore, it is better to rejoice at the birth of a baby and do everything to keep his eyes healthy and maintain the health of such an important organ throughout his life.

Each trait in the body is inherited according to a certain type and is encoded in six different genes. This means that depending on the presence of signs in both the father of the child and the mother, it is possible to predict the amount of melanin in the baby. This amount will determine the appropriate shade of the iris.

What exactly determines the color of the eyes of a child? The staining itself is determined by the presence of a specific organic compound - the melanin pigment. In the stroma (the supporting structure of organs) are melanocytes, or pigment cells that produce melanin. The more pigment is contained in the stroma, the more intense the staining of the eyes.

There are three main gradations of pigment content:

blue - the minimum amount;
green - medium;
brown - maximum.

Also, the chemical variations of the organic compound affect the trait. The pattern depends on the amount of melanin, which determines the tone of the skin as a whole.

There are rare cases of a specific genetic pathology when melanin in the cells of the iris is completely absent. Then translucent blood vessels give the eyes a red tint.

Blue colour

Using the table, let's guess what kind of eyes the baby will have, not forgetting that each color has several nuances. Brown - not only brown, also honey, amber, onyx; blue is indigo or brilliant blue, and among grays there are silver or pewter.

Despite scientific knowledge and genetics, it is worth remembering that life always presents amazing exceptions to all the rules and laws.

And some more interesting information can be found in the following video.

The table for determining the color of the eyes of a child differs from ordinary tables, because it has few numbers and values. A table with the Rh factor was compiled in a similar way, they are similar to each other. The left column represents combinations of pairs of parents' eyes depicted as color patterns: hazel hazel, hazel green, blue green, etc.

The top line of the table also depicts eyes with the color that a born baby can have: brown, green or blue-gray. And at the intersection of columns and rows, the probability values are indicated as a percentage. Therefore, it is quite easy to understand the sign.

For example, if one parent has blue eyes and the other parent has brown eyes, there is a 50% chance that a newborn will develop a brown tint as they grow older, and a 50% chance of blue-gray, and the chance of green eyes is 0. %. Similarly, you can understand the information for other options.

Eye color from grandparents to our grandchildren is genetically transmitted. During pregnancy, many parents can't wait to find out what eye color their unborn child will have. All answers and tables for calculating eye color are in this article. Good news for those who want to pass on their eye color to their descendants: it is possible.

Recent studies in the field of genetics have discovered new data on the genes that are responsible for eye color (previously, 2 genes responsible for eye color were known, now there are 6 of them). At the same time, genetics does not have answers to all questions regarding eye color today. However, there is a general theory that, even with the latest research, provides a genetic basis for eye color. Let's consider it.

So: each person has at least 2 genes that determine eye color: the HERC2 gene located on the 15th human chromosome, and the GEY gene (also called EYCL 1), which is located on the 19th chromosome.

Below is a diagram that shows the "chances of success" of a particular eye color (in % ratio) depending on the color of the eyes of the parents.

Also look at the site - determining the color of the child's eyes by the color of the eyes of the baby's parents and the color of the eyes of your parents. This is an English-language resource, but it will not be difficult to figure out what's what.

How reliable is this? Let's check together! Please unsubscribe in the comments if the color of the eyes in reality coincided with the predictions calculated and proposed by these methods.

How to determine the color of the eyes in a baby

As you know, the color of the baby's eyes can have different shades. Depending on the conditions, mood, weather and even the time of day, it may undergo some changes. Various diseases, stresses and injuries can permanently change the color of the iris of a child, due to the complex processes of healing and restoration of the structure of the eyeball.

The following factors can cause eye color change:

long crying;
natural or artificial lighting;
weather;
the color of the clothes worn by the baby;
infectious diseases of the eyeball and eyelids;
child nutrition;
lack of sleep;
eyeball injury.

How can you correctly determine the color of the eyes of a child? Wait until your baby is in a good mood: full, happy and cheerful. Bring the baby closer to the light source and carefully look at his eyes. Most often it is very difficult to distinguish between blue and green shades.

The birth of a child is a small miracle. Even when the baby is growing in the mother's womb, future parents, their immediate family and friends are actively trying to predict what color the baby's eyes will be. Sometimes it happens that a child is born with light gray or blue eyes, although his mother and father are brown-eyed. But closer to the year, the baby's eyes become dark. What is the reason for this phenomenon and how to explain the presence of different eye colors in newborn children?

What color are the eyes of newborns

Eyes are the mirror of the soul. Any eye color is beautiful and has its own characteristics. In young children, the formation of the final eye color may occur during the first three years life. But if you look at the parents and close relatives of the baby, you can guess what color the eyes of an already grown child will be.

How is the color of the iris formed?

In the process of intrauterine development of the fetus, as early as the eleventh week, the iris of the eye begins to form. It is she who determines what eye color the baby will have. The process of inheritance of the color of the iris is very complex: several genes are responsible for it at once. Previously, it was believed that mom and dad with dark eyes there is absolutely no chance of giving birth to a light-eyed baby, but recent studies have proven that this is not the case.

With the help of this table, you can guess the color of the eyes of the unborn child

The color and shade of the iris depends on two factors at once:

the density of the cells of the iris;
the amount of melanin in the child's body.

Melanin is a special pigment produced by skin cells. It is he who is responsible for the saturation and intensity of the color of our skin, hair and eyes.

Accumulating in the iris of the eye in large quantities, melanin causes the formation of black, dark brown or hazel colors. If it is not enough, children are born with blue, gray and green eyes. People with total absence melanin in the body are called albinos.

There is a misconception that all small children are born blue-eyed. In fact, this is not always the case. A baby is born with a certain density of iris cells and the amount of melanin in it given by nature, so the eyes appear bright. In the process of growing up, growth and development of the child's body, this pigment accumulates in the iris, due to which a different eye color is formed. Thus, the phenomenon of turning blue eyes in an infant into dark and even black is quite easy to explain. Do not forget that many children are immediately born with brown eyes.

Yellow and green eyes

Green and yellow eyes are the result of a small amount of melanin in the iris. The shade of the eyes is also determined by the presence of lipofuscin pigment in the first layer of the iris. The more it is, the brighter the eyes. Green eyes have slight inclusions of this substance, which causes the variability of their shades.

The green color of the eyes in a child is formed closer to the second year of life.

Yellow eyes, contrary to popular rumors, are not an anomaly. Very often, yellow-eyed babies appear in brown-eyed parents. In most cases, this eye color darkens with older age, but some children remain with yellow eyes for life.

Yellow eye color in an adult is a rarity all over the world.

There are several interesting facts about green and yellow eyes. For example, women are more likely to have green irises than men. During the Middle Ages, green-eyed women were considered witches and burned at the stake according to ancient superstitions - this may explain such a small number of people with green eyes at the present time. Yellow eyes are a rarity: they occur in less than two percent of the population worldwide. They are also called "eyes of the tiger".

Red eyes

The red color of the eyes in a child is a sign of severe genetic disease called albinism. Albinos have practically no melanin pigment: this is due to their snow-white skin color, hair and red or colorless eyes.

Albinos have red eyes.

The reddish hue of the iris is due to the fact that blood vessels shine through it in the light. Albinism is a rather serious pathology, and a lot of effort will have to be made to raise such a child. You will need to use special glasses and protective creams, as well as regularly show the growing baby to the pediatrician.

Melanin, which is so lacking in albinos, provides protection from sunlight. That's why White skin these people instantly burns in the sun. Development risk malignant neoplasms these children are much higher than others.

It is noteworthy that this pathology is not a mutation, but a consequence of a genetic lottery: the distant ancestors of both parents of a person born with red eyes once suffered from a lack of melanin. Albinism is a recessive trait and can only appear if two identical genes meet.

Albinism is often combined with other congenital malformations: cleft lip, bilateral deafness and blindness. Albinos often suffer from nystagmus, abnormal movements of the eyeball that occur without their intention.

Blue and blue eyes

Blue eyes in newborns occur due to the low density of cells in the outer layer of the iris, as well as due to the low content of melanin in it. Light rays of low frequency completely disappear in the posterior layer of the iris, and high-frequency rays are reflected from the front, as if from a mirror. The fewer cells in the outer layer, the brighter and more saturated the color of the baby's eyes will be.

About ninety-five percent of the population of Estonia and Germany before World War II had blue eyes. Blue eyes are more sensitive to light. When a blue-eyed person is happy or scared, their eyes may change color.

Blue eyes can change their color depending on the lighting.

Blue eyes are when the cells in the outer layer of the iris are denser than blue, and also have a grayish tint. Most often, blue and blue eyes can be found in Caucasians. But there are exceptions.

People with blue eyes are less susceptible to the tearing effect of onions when peeling them. Most blue-eyed people live in the northern parts of the world. Blue eyes are a mutation that arose over ten thousand years ago: all blue-eyed people are very distant relatives of each other.

Gray and dark gray eyes

The mechanism of formation of dark gray and gray eyes does not differ from blue and blue. The amount of melanin and the density of iris cells is slightly greater than that of blue eyes. It is believed that a child who was born with gray eyes can subsequently receive both a lighter and a darker shade. It can be said that grey eyes are the transition point between these two shades.

Gray eyes are common in babies.

Black and brown eyes

Owners of black and brown eyes can boast the largest number melanin in their irises. This eye color is the most common in the world. Black or "agate" eyes are widespread among the peoples of Asia, the Caucasus and Latin America. It is believed that initially all people on earth had the same amount of melanin in the iris and were brown-eyed. Completely black eyes, in which the pupil cannot be distinguished, occur in less than one percent of the population.

Most brown-eyed people in the world

Very often, children with brown eyes have dark hair, eyebrows and eyelashes, as well as a swarthy skin tone. Dark-eyed blondes are now a rarity.

There is a laser operation with which it is possible to remove some of the pigment and brighten the eyes: the Japanese widely use this method. In ancient times, it was believed that people with brown eyes could see well in the dark, and this allowed them to hunt at night.

colorful eyes

Multi-colored eyes - very a rare event, a genetic mutation called heterochromia. This is due to a change in the gene structure that encodes the melanin pigment: due to this, the iris of one eye receives a little more melanin, and the other a little less. Such a mutation does not affect vision in any way, so heterochromia is an absolutely safe phenomenon.

There are several types of multi-colored eyes:

total heterochromia: both eyes are uniformly colored in different colors;
Complete (total) heterochromia is very rare.
partial, or sector: in one of the eyes there is a bright blotch of a different color;
Many people have multicolored patches in their eyes.
circular heterochromia: several rings of different colors around the pupil.
Circular heterochromia occurs in 5% of the population

Multi-colored eyes are not a sign of any disease, but rather interesting and unusual phenomenon which makes the child unique and unrepeatable in its own way. Many Hollywood stars also had a similar "defect", which they turned into their highlight.

Famous people with heterochromia:

David Bowie;
Kate Bosworth;
Mila Kunis;
Jane Seymour;
Alice Iv.

How to determine the color of the eyes in a baby

When blue-eyed babies cry, their eyes turn aqua blue.

The following factors can cause eye color change:

long crying;
natural or artificial lighting;
weather;
the color of the clothes worn by the baby;
infectious diseases of the eyeball and eyelids;
child nutrition;
lack of sleep;
eyeball injury.

How can you correctly determine the color of the eyes of a child? Wait until your baby is in a good mood: full, happy and cheerful. Bring the baby closer to the light source and carefully look at his eyes. Most often it is very difficult to distinguish between blue and green shades. Most of all, the difference between them is noticeable in daylight natural light.

If you want to at least approximately determine the color of the eyes of an unborn baby, you should turn to genetics. He will draw up a family tree for you, taking into account the color of the iris of your next of kin. You must come to the appointment with your spouse and with photographs of the baby's grandparents.

When does eye color change in newborns?

Usually the final shade of the iris is formed by the third year of a child's life. Sometimes there may be exceptions when the color of the eyes forever remains the same as at birth, or changes again at puberty. According to some studies, people who are initially born with dark eyes are much less likely to change the color of the iris throughout their lives. In newborns with light and rare shades of eyes, the formation of the final color occurs much later.

Table: change in the color of the eyes of a newborn child depending on his age

When the color of the whites of the eyes indicates pathology

The white of the eye, otherwise known as the sclera, is a unique indicator of the condition. internal organs person. Normally, the sclera has completely White color, and resembles boiled chicken protein, hence its second name. And also it has on its surface the smallest capillaries that carry arterial and venous blood. A change in the color of the eyeball directly indicates the pathology in the body.

Red whites of the eyes

If your baby has reddened eyes, this may indicate at once several types of pathological processes that occur in his body. However, you should not be very scared and panic: in most cases, the redness disappears within a few days when correct application eye drops.

Eye redness indicates corneal irritation

Causes of redness of the white of the eye:

SARS and colds;
conjunctivitis;
pollution;
barley formation;
protein damage: scratch or impact;
inflammation of the sacs.

If the baby is restless, constantly trying to touch the eye, he has a fever, you should immediately consult a doctor. If the treatment of this disease does not require special means, you will need to buy special baby drops and bury the crumbs in their eyes three times a day. If there are more serious pathologies associated with an infectious lesion of the protein, the child will be prescribed an antibiotic and eye ointments.

Yellow whites of the eyes

When a newborn baby has yellow sclera, skin and mucous membranes, we should talk about jaundice. This type of pathology is very common in premature babies, as well as in babies whose mother had an Rhesus conflict.

The yellow color of the skin and whites of the baby's eyes is associated with an excess of bilirubin.

Rh conflict is a situation that occurs when the Rh of a woman and a man are incompatible, as a result of which an Rh-negative mother bears an Rh-positive child.

The yellowness of the baby is due to the presence in his blood of a large amount of a special enzyme called bilirubin. The more it is in the body, the more intense the color. Bilirubin appears due to increased destruction blood cells in the baby's liver. This is due to the fact that when the baby was in the mother's body, he had a completely different hemoglobin (the protein that carries oxygen to the cells of the body). At birth, infant hemoglobin is replaced by an adult one, which is associated with impaired adaptation mechanisms, destruction of blood cells and the formation of jaundice. This condition usually resolves within a few days without treatment.

If a woman with an Rhesus conflict had a rather difficult pregnancy and had significant complications and pathologies, there is a risk of developing a more severe form of jaundice. Usually, after the birth of such children, they are taken to intensive care, where they carry out all the necessary measures to restore balance in the body. The duration of treatment for jaundice in newborns is from two to six months.

Blue whites of the eyes

Children who are born with blue or bluish whites of the eyes are carriers of a severe genetic disorder called Lobstein van der Hewe syndrome. This is a rather complex and multifactorial disease that affects the connective tissue, visual apparatus, hearing organs and the skeletal system. Such a baby will be treated in the hospital for a long time, but he will not be able to completely get rid of the pathology.

Syndrome blue sclera- severe genetic disorder

This genetic anomaly is dominant: a person with this disease will have a sick child. Fortunately, the syndrome is quite rare: one case in sixty or eighty thousand babies a year.

Main clinical manifestations syndrome:

bilateral hearing impairment associated with underdevelopment of the internal ear canal and auditory ossicles;
frequent bone fractures and torn ligaments: the connective tissue sheath is not able to withstand pressure, and even a slight blow can lead to serious injury;
blue coloring eyeballs due to the fact that the thin sclera, passing through itself the rays of light, reflects the pigment of the iris;
significant visual impairment is directly dependent on the pathologies of the sclera.

Unfortunately, since the disease is a violation of the genetic structure, it is not possible to completely cure it. Usually, doctors prescribe symptomatic treatment, which is aimed at reducing the intensity of the main manifestations. And also, when the child reaches a certain age, it is possible to perform operations that will help restore vision and hearing. Parents of such a baby should be extremely careful not to accidentally provoke fractures or other injuries.

Thanks to the achievements modern medicine and genetics, it is possible to determine the color of your baby's eyes even before he is born. Of course, these results will only be approximate. The inheritance and formation of the color of the iris is a rather complex and interesting process. However, for most parents it does not matter at all what color the eyes of their newborn will be, if only the child grows and develops without any diseases and pathologies. If you notice that the color of the baby's eyeballs is different from the norm, you should immediately contact your pediatrician and endocrinologist.

Many parents wonder what color the eyes of their unborn baby will be. The answer will not be so simple. Eye color is determined by certain genes that are passed on to the child from the parents. Questions of their inheritance even modern science have not been studied so well as to say for sure what facial and character traits a child will inherit from his mother and father.

Melanin, a pigment found in the iris, is responsible for eye color. Melanin is also responsible for the color of our skin. Blue-eyed people have the least amount of this pigment, while brown-eyed people have the highest amount. People with a different eye color are somewhere in the middle of these two extremes. How much melanin will be contained in the iris of the eye depends on hereditary characteristics.

Simply put, the child inherits the genes of both parents, their combination will determine what color the child's eyes will be. The real eye color may not appear in a child immediately. It is known that all children are born with blue (gray) or brown (black) eyes. If the baby's skin is light, then it is most likely that he will have blue eyes at birth, if the skin is dark, then the baby will be born with brown eyes. As the child grows, more and more melanin will begin to be produced, which will determine the true color of your child's eyes. This process can take about three years. Although, as observations show, most babies acquire their real eye color within six months after birth. It is absolutely possible that a child born with light eyes can become brown-eyed with age. For some people, eye color changes even after the age of 20.

It is not true to say that brown-eyed parents can only have a child with brown eyes. Medicine knows many examples of how parents with dark eyes gave birth to children with blue eyes. Of course, the color of the eyes of the father and mother can predict the probable color of the baby's eyes, but one cannot be one hundred percent sure of this. The same can be said about green (or any other) color. If parents have the same eye color - this does not mean that your baby will be the owner of the same eyes.
