Will your baby have blue eyes? There is no way to be totally sure, but you can make a good guess. A Genetic Explanation. Blue is one of the rarest eye colors worldwide. The genetic mutation behind blue eyes actually switches off the gene that colors eyes brown what is in the next update for minecraft pe leaves them blue.
Everyone with blue eyes is related to a single, common ancestor. This ancestor most likely lived close to the Baltic Sea between six and ten thousand years ago. Melanin is the pigment that colors the human body. Eye color depends on how much of it is stored in the iris. There are many different eye colors, existing along a continuum.
The least amount of melanin produces blue eyes. More produces green eyes, and even more produces brown eyes, which is the most common eye color worldwide.

Interestingly, blue eyes only appear that way. There is no blue pigment in the human iris or anywhere in the human body. Varying levels of melanin are responsible for eye color. Melanin is brown, and little to no melanin makes the eyes appear blue. When light scatters, the longest wavelengths are blue, so that is what we see. This is the same reason that the sky and the ocean appear blue. Will your baby have any chance of being born with blue eyes?
Look at your family background first. People with blue eyes usually have European ancestry. If either you, your partner, or anyone in your direct or second line of heredity parents, grandparents, siblings, or aunts and uncles has blue eyes, there is a chance that your baby could. We all inherit two copies of each gene alleleeye color included. One copy comes from our mother, and one from our father.
Both alleles are stored in our genetic code and can be passed on to our children, but only one presents in how we look. Generally, darker colors dominate so a person with one gaby gene and bxby blue-eyed gene will have brown eyes.
The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby.
It is important to remember that this theory is a simplified version of what really happens at the genetic level. Human coloring is actually controlled by a complex genetic process and eues are many different eye colors.
Your baby could be born with blue eyes, but it might not stay that way. In fact, nearly all Caucasian babies have blue eyes at birth. In most cases; however, the eyes darker over the first year or two. Melanin production kicks in over time. So will your baby be born with blue eyes? If you or others in your family have them, it is more likely. However, blue eyes are rare. And even if your baby is born with blue eyes, there is no telling if the color will stick.

Chances Of Your Baby Eye Color
Aug 03, · Two blue-eyed parents are very likely to have a blue-eyed child. Two brown-eyed parents are more likely to have a child with brown eyes. If one of the grandparents has blue eyes, the chances of having a blue-eyed baby increase slightly. If one parent has brown eyes and the other has blue eyes, eye color is more of a toss zi255.comted Reading Time: 6 mins. Aug 07, · Generally, darker colors dominate so a person with one brown-eyed gene and one blue-eyed gene will have brown eyes. The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby. Here are the possibilities: Blue eyes + blue eyes = % . Two Pairs of Mixed Genes. Here, each child has a 1 in 4 chance of inheriting two recessive genes and having blue eyes, and a 3 in 4 chance of inheriting a dominant gene for brown eyes. The brown-eyed offspring may have either a pair of dominant genes, or mixed genes. Recessive and Dominant Genes.

Of the many physical characteristics expectant parents muse about, the color of their baby's eyes is arguably one of the most common. But although eye color is determined by genetics , it takes a year for a child's permanent eye color to develop.
It is common for parents to wonder why their bouncing blue-eyed baby is sporting hazel peepers as a toddler. During the first year of life, a baby's eye color will change as the eye takes on its permanent hue. Understanding how eyes get their color and the role genetics play can take some of the mystery out of this phenomenon. And while eye color is mostly a matter of aesthetics, it sometimes can be an indication of certain health issues.
Scientists once believed eye color was determined by a single gene, but advances in genetic research and genomic mapping have revealed that more than a dozen genes influence eye color. The colored part of the eye is the iris. What we perceive as eye color is a combination of pigments produced in a layer of the iris known as the stroma.
The combination of pigments, as well as how densely they're dispersed and how they're absorbed by the stroma, determine whether an eye looks brown, hazel, green, gray, blue, or a variation of those colors.
For example, brown eyes have denser concentrations of melanin than green or hazel eyes. Interestingly, blue eyes have very little pigment and appear blue for the same reason the sky and water appear blue—by scattering light so that more blue light reflects back out. A newborn's eyes typically are dark and the hue often correlates to skin tone. Caucasian babies tend to be born with blue or grey eyes, while Black, Hispanic, and Asian babies commonly have brown or black eyes.
However, at birth pigment is not widely distributed in the iris. During the first six months of life, pigment epithelial cells start to pump melanin, pheomelanin, and eumelanin into the stroma. By age 1, eye color is usually set. Eye color is determined by multiple variations of genes that direct the production and distribution of melanin, pheomelanin, and eumelanin.
Each gene has two different versions alleles —one inherited from the mother and one inherited from the father. If the two alleles of a specific gene are different heterozygous , what is known as a dominant trait is expressed. The unexpressed allele is recessive. If a trait is recessive, like blue eyes, it generally only appears when the alleles are the same homozygous.
Brown eye color is a dominant trait and blue eye color is a recessive trait. Green eye color is a mix of both. Green is recessive to brown but dominant to blue.
Without knowing precisely which genes a baby will have it's not possible to predict with total certainty what color their eyes will be, but there are ways to make fairly accurate predictions.
One of these is by using a simple grid chart called the Punnett square on which genetic traits of one parent are entered in the top rows of the grid and those of the other parent are entered in far-left columns. As a dominant trait, brown eyes can result from six different genetic combinations and can hide recessive traits of green or blue eye color.
To factor in hidden recessive traits, it is helpful to know the grandparents' eye colors. Scientists have begun to develop methods for predicting eye color using genetic tests that identify specific polymorphisms that can indicate how much melanin, pheomelanin, and eumelanin will be produced as well as the degree of pigment saturation in the iris.
A baby's eye color may also reveal congenital diseases and other conditions. Babies whose eyes are different colors—known as heterochromia—may have Waardenburg syndrome , a genetic condition that can cause hearing loss in one or both ears. People with Waardenburg syndrome may also be born with very pale eyes or one eye that is two colors. Very pale blue eyes may be caused by ocular albinism , in which there is a total absence of pigment in the iris.
As an X-linked recessive disorder , ocular albinism occurs almost exclusively in men since they have two X chromosomes. Women, who have an X and a Y chromosome, may be carriers.
Studies suggest fewer than one out of every 60, men has ocular albinism. A baby also may be born missing all or part of their iris, a genetic condition known as aniridia caused by mutations in the PAX6 gene, which plays a critical role in the formation of tissues and organs during embryonic development.
While understanding the genetics of eye color can offer a probability of eye color, there are no certainties. If you have any questions about your child's eye color or overall eye health, bring your concerns to their pediatrician.
