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.

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.

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.

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.

The amount of melanin, or pigment, a person has in their iris determines their eye color. So, the more melanin you have, the darker your eyes appear. Globally, brown is the most common eye color. In ...
