A team of scientists has tracked down a genetic mutation that leads to blue eyes. The mutation occurred between 6, and 10, years ago. Before then, there were no blue eyes. The mutation affected the so-called OCA2 gene, which is involved in the production of melanin, the pigment that gives color to our hair, eyes and skin. The genetic switch is located in the gene adjacent to OCA2 and rather than completely turning off the gene, the switch limits its action, which reduces the production of melanin in the iris. In effect, the turned-down switch diluted brown eyes to blue.
General Education. Martin Fugate, a French orphan, married a woman named Elizabeth around They settled in Troublesome Creek, Kentucky. Unbeknownst to the couple, they were coincidentally both carriers of a recessive gene met-H that caused methemoglobinemia, which can tint the skin of sufferers blue.

You might have known that melanin determines our hair and skin color, but miniature melanin cells, called melanocytes, are found in the iris as well. Here's the shocker: There's really only one "shade" of melanin — and it's brown!
