Eye Color Genetics Eye color is determined by different versions of genes that control how melanin, pheomelanin, and eumelanin are made and spread in the iris. The two main genes responsible for ...

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 genetics not so simple, study finds Date: March 11, 2021 Source: King's College London Summary: Researchers have identified 50 new genes for eye color in a study involving the genetic ...

Genetics add another layer to the process, determining how much melanin an individual’s iris will produce. But, unlike simple inheritance patterns, eye color isn’t determined by a single gene.

New research links specific inherited genetic differences (alterations) to an increased risk for eye (uveal) melanoma, a rare form of melanoma that arises from pigment cells that determine eye color.

Eye color depends on the amount, type and distribution of melanin, or pigment, in the iris of the eye, said Blair Stevens, a clinical genetic counselor and the director of prenatal genetic ...
