A child’s eye color depends on the pairing of genes passed on from each parent, which is thought to involve at least three gene pairs. The two main gene pairs geneticists have focused on are ...

Exactly how is a person's eye color determined? It depends on the amount, type and distribution of melanin, or pigment, in the iris of the eye, a genetics expert reveals — and more.

Eye color phenotypes demonstrate both epistasis and incomplete dominance. ... Over 300 SNPs for eye color have been identified on the gene, but classification of their results proved too arduous.

A newborn's eye color is usually related to their skin tone. White babies tend to be born with blue or sometimes gray eyes. Black, Hispanic, and Asian babies commonly have brown or black eyes.

Sturm’s career is focused on unpacking the genetics of human pigmentation, including eye color. “Multiple genes contribute to eye color, but the main player is OCA2,” he says.

But, unlike simple inheritance patterns, eye color isn’t determined by a single gene. Multiple genetic markers contribute to the final shade, making it not always easy to predict the final outcome.

Stevens said there still is much to be learned about the genetics of eye color. She also said eye color can’t be reliably predicted using genetic testing. Filed under. eyes ...
