Answers
Answer -
Eye colour eyes is determined by the amount of melanin in the iris, density of proteins, and the frequency of the scattering of light by the turbid medium in the stroma of the iris. The colour of the iris is determined by the amount of melanin pigments, the way the melanin is distributed in the eye and the ratio of eumelanin to pheomelanin. Eye colours have been divided into nine categories and as many as 16 genes have been associated with eye colour inheritance. The main genes associated with eye colour include OCA2 and HERC2 and both are located in Chromosome 15.
