â¢ Eye color was traditionally described as a single gene trait, with brown eyes being dominant over blue eyes. â¢ Today, scientists have discovered that at least eight genes influence the final color of eyes.The genes control the amount of melanin inside specialized cells of the iris. Eye color was traditionally described as a single gene trait, with brown eyes being dominant over blue eyes. â¢ Today, scientists have discovered that at least eight genes influence the final color of eyes.
The mutation affected a gene called OCA2 and âliterally 'turned off' the ability to produce brown eyesâ, he says. OCA2 is involved in the production of melanin, the pigment that gives colour to hair, eyes and skin. The mutation in the adjacent gene does not switch off the OCA gene entirely but limits its action, reducing the production of melanin in the iris of the eye â âdilutingâ brown eyes to blue. If the OCA2 gene had been completely turned off, those who inherited this mutation would be without melanin in their hair, eyes or skin colour - albino.
