Detailed explanation-1: -In the most elementary form, the inheritance of eye color is classified as a Mendelian trait. On the basis of the observation of more than two phenotypes, eye color has a more complex pattern of inheritance. Eye color ranges include varying shades of brown, hazel, green, blue, gray, and in rare cases, violet and red.

Detailed explanation-2: -For example, do some humans have one blue eye and one green eye, or are these traits just incomplete dominance? There are definitely codominant traits in people. But having two different colored eyes is not one of them. This heterochromia happens for different reasons (click here to learn more).

Detailed explanation-3: -Eye color is an example of incomplete dominance. According to this law of dominance, hybrid offspring will only inherit dominant traits in phenotype. Such alleles which are suppressed are called the recessive traits while alleles that determine the trait are known as dominant traits.

Detailed explanation-4: -Eye color genes To date, eight genes have been identified which impact eye color. The OCA2 gene, located on chromosome 15, appears to play a major role in controlling the brown/blue color spectrum. OCA2 produces a protein called P-protein that is involved in the formation and processing of melanin.
