DOES THE COLOUR OF EYE DEPEND UPON THE COLOUR OF IRIS? WHY
The colored part of the eye is called the iris, which has pigmentation that determines our eye color.
Human eye color originates with three genes, two of which are well understood. These genes account for the most common colors green, brown, and blue. Other colors, such as gray, hazel and multiple combinations are not fully understood or explainable at this time.
