Blue eyes genetics

Where Do Blue Eyes Come From?

Humans have many phenotypic variations in eye color which is determined by multiple genes. So far, up to 16 genes have been associated with eye color inheritance. However, scientists from the Institute of Forensic Genetics at the University of Copenhagen discovered that the reason for blue eyes mainly lies in two genes: OCA2 and HERC2. This way they have shown that the earlier belief that blue eye color is a simple recessive trait is incorrect.
