The color of babies' irises actually depends on melanin, a protein secreted by special cells called melanocytes that also give your baby's skin its color. Babies whose heritage is dark-skinned are usually born with brown eyes, whereas Caucasian newborns tend to be born with blue or gray eyes.
Because it takes about a year for melanocytes to finish their work it can be a dicey business calling eye color before the baby's first birthday. The color change does slow down some after the first 6 months of life, but there can be plenty of change left at that point.
A newborn's eyes typically are dark, and the color is often related to their skin tone. White babies tend to be born with blue eyes or sometimes gray eyes. Black, Hispanic, and Asian babies commonly have brown or black eyes.
Your children inherit their eye colors from you and your partner. It's a combination of mom and dad's eye colors – generally, the color is determined by this mix and whether the genes are dominant or recessive. Every child carries two copies of every gene – one comes from mom, and the other comes from dad.
What is the rarest eye color? Green is the rarest eye color in the world, with only 2% of the world's population (and fewer than one out of ten Americans) sporting green peepers, according to the American Academy of Ophthalmology (AAO).
Flexi Says: Two brown-eyed parents (if both are heterozygous) can have a blue-eyed baby. If both the parents have brown eyes, then there is generally a 25% chance for their child to have blue eyes. Because both the brown-eyed parents have a recessive blue-eye gene and can pass it to the next generation.
It can take as long as 9 to 12 months for your baby's permanent eye color to be determined and the change is so gradual, you might not even notice it happening. But by baby's first birthday, you can be pretty sure whatever big eyes are staring down that smash cake are the ones they'll have for life.
When it comes to genetics, there really isn't a distinct formula that will help you to predict what color eyes, hair, or even skin color your child is going to have. And although if you and your spouse both have brown eyes, your child is more likely to have brown eyes as well, there really isn't any sort of guarantee.
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 takes about a year for the melanocytes to finish their job and for the final color to come in. While the rate of color change does slow down after 6 months, the color can still change after this time. Sometimes the color change can continue for several years before the eye color becomes permanent.
What color will GRAY babies' eyes turn? If your child is born with gray eyes they may stay light or actually turn hazel or brown during the course of your child's first year of life. It's part of what makes being a parent so much fun.
Babies often do not have much pigment in their irises when they are born. This is why their eyes can look very blue. More pigment accumulates in the iris over the first few months of a child's life and blue eyes can become less blue or even turn completely brown.
Generally, changes in eye color go from light to dark. So if your child initially has blue eyes, their color may turn green, hazel, or brown. But if your baby is born with brown eyes, it is unlikely that they are going to become blue.
The first 6–9 months is generally when you will see the most changes in your baby's eye color. Due to the production of melanin, their eyes may begin to darken. You likely won't notice it all of a sudden; it will often appear fairly gradually. At 12 months, many babies have their 'final' eye color.
Baby eye color is genetic, and genes pass from generation to generation. So if one grandparent had blue eyes, but the other had brown eyes, and you were born with brown eyes, and had a baby with another brown-eyed person, there is a chance that baby could be born with blue eyes.
Both parents with brown eyes: 75% chance of baby with brown eyes, 18.8% chance of baby with green eyes, 6.3% chance of baby with blue eyes. Both parents with blue eyes: 99% chance of baby with blue eyes, 1% chance of baby with green eyes, 0% chance of baby with brown eyes.
A study found that many babies (both male and female) had darker hair for the first six months of life, and lighter hair between 9 months and 30 months of age. Then, after the age of 3, the subjects' hair became progressively darker until they turned 5.
A condition is considered Y-linked if the altered gene that causes the disorder is located on the Y chromosome, one of the two sex chromosomes in each of a male's cells. Because only males have a Y chromosome, in Y-linked inheritance, a variant can only be passed from father to son.
When broken down by gender, men ranked gray, blue, and green eyes as the most attractive, while women said they were most attracted to green, hazel, and gray eyes.
Both parents have to pass along the blue eye gene in order for their child to have blue eyes.
The rarest hair and eye color combination is red hair with blue eyes, occurring in less than 1% of the global population. This statistic is a powerful reminder of the uniqueness of the red hair and blue eyes combination.
The largest concentration of green eyed people is in Ireland, Scotland and Northern Europe. In Ireland and Scotland, 86% of people have either blue or green eyes. There have been 16 genes identified that contribute to eye colour.
Purple eyes are also commonly referred to as “violet eyes,” as they are typically a light shade. For most people, this striking eye color can only be achieved with the help of colored contacts. But the fact is that a small (albeit very small) percentage of people are indeed born with purple eyes.
