Where do blue eyes come from inbreeding?

Where do blue eyes come from inbreeding?

“The mutations responsible for blue eye colour most likely originate from the north-west part of the Black Sea region, where the great agricultural migration of the northern part of Europe took place in the Neolithic periods about 6,000 to 10,000 years ago,” the researchers report in the journal Human Genetics.

Does inbreeding cause different colored eyes?

Different colored eyes are pretty rare in people although it is more common in some animals. For example, dogs like Siberian Huskies and cats and horses often have different colored eyes because of inbreeding.

Why did humans develop blue eyes?

A team of scientists has tracked down a genetic mutation that leads to blue eyes. The mutation occurred between 6,000 and 10,000 years ago. 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.

Why do some people have blue eyes?

The cause of blue eyes is a mutation in which a genetic switch limits the production of melanin in the iris. According to genetics research, all people with blue eyes have a common ancestor who lived as a hunter-gatherer in a cave near the Black Sea approximately ten thousand years ago:

Where did blue eyes originate from?

Blue eyes originated about 10 000 years ago in the Black Sea Region: Blue Eyes Originated 10,000 Years Ago in the Black Sea Region – Top US & World News | Susanne Posel. Eye color – Wikipedia. The genes for blue eyes were then taken into Europe, Middle East, North Africa and Asia by ancient migrating humans.

What is blue eye mutation?

Blue eyes are the result of a mutation that first occurred around 6,000 to 10,000 years ago. Piotr Krzeslak/Shutterstock. Every blue-eyed person on the planet is descended from a single European who lived around 6,000 to 10,000 years ago, and who first developed a specific mutation that accounts for the now widespread iris coloration.
