Detailed explanation-1: -Eye color is determined by variations in a person’s genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount of melanin in the front layers of the iris.

Detailed explanation-2: -We now know that eye colour is actually a complex genetic trait, involving interaction of some major genes and many minor genes. This Mendelian-Complex genetic explanation for eye colour also crosses over into the genetics of many other eye diseases such as age-related macular degeneration and glaucoma.

Detailed explanation-3: -Examples of biological traits are as follows: hair color, eye color, blood type, skin color, height, and sex.

Detailed explanation-4: -Eye color is a polygenic phenotypic character determined by two factors: the pigmentation of the eye’s iris and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris.
