How is Eye Color Determined?
The color of the human eye is a polygenic phenotype that is determined by the frequency-dependence of how light is scattered in the medium present in the stroma and the pigmentation of the iris. The eye color of human beings varies from black to light brown depending on melanin content in the epithelium pigment of the iris, stroma’s cellular density, and melanin concentration in the iris stroma. The ocular fluid and iris have no blue pigmentation. The iris is brownish-black due to the presence of melanin. Blue eyes have low melanin content.
