Your question: What determines a baby’s eye color?

What determines a babys eye Colour?

Your baby’s eye color is determined by genetics. Eye color is a combination of pigments produced in the stroma. Brown eyes have more melanin than green or hazel eyes. Blue eyes have very little pigment.

What is the dominant gene for eye color?

The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.

When can you tell a baby’s true eye color?

Permanent eye color is not set until a baby is at least 9 months old, so wait until your child’s first birthday to determine what color they will be. Even then, sometimes you may find little surprises. Subtle color changes can still occur all the way up until about 3 years of age.

Can 2 brown eyes make hazel eyed baby?

Not really. Two brown-eyed parents are likely to have a brown-eyed child, but could potentially have a child with blue, green or hazel eyes, depending on the combination of genes from each parent.

Can a blue-eyed and brown-eyed parents?

Eye color is not an example of a simple genetic trait, and blue eyes are not determined by a recessive allele at one gene. Instead, eye color is determined by variation at several different genes and the interactions between them, and this makes it possible for two blue-eyed parents to have brown-eyed children.
