What determines eye color?

Question

i am wondering if there is anything specific that determines someone's eye color. I know that it is genetics, i mean like parents, birth deffects, anything that could affect it.

Answer 1

well i know that dominant eyes are brown. Therefore blue are recessive. If the child has parents with both blue eyes then they will have blue eyes. If they are darker then they have atleast one dominant gene for brown. That would mean that there could still be a likely chance for blue if they are both one dominant and one recessive gene for each parent. that gives only a 25% chance they would be blue. But if one of the parents carries 2 dominant then the child will not have blue eyes. I hope this wasnt confusing. It would be easier if you knew wat dominant and recessive are. If you dont no then i recommend looking them up. Ull understand this after.  Genetic Traits...

I hope this helped

Good Luck!

Answer 2

Eye color is inherited (it is a polygenic trait) and is basically determined by the concentration of melanin in the iris.

Answer 3

Eye color is a polygenic trait and is determined by the amount and type of pigments in the eye's iris.

Three main elements within the iris contribute to its color: the melanin content of the iris pigment epithelium, the melanin content within the iris stroma, and the cellular density of the iris stroma.[5] In eyes of all colors, the iris pigment epithelium contains the black pigment, eumelanin.[2][5] Color variations among different irises are typically attributed to the melanin content within the iris stroma.[5] The density of cells within the stroma affects how much light is absorbed by the underlying pigment epithelium.[5]
