What originally caused blue eyes?

Originally we all had brown eyes, however, according to researchers at the University of Copenhagen, it appears that a genetic mutation in a single individual in Europe 6,000 to 10,000 years ago led to the development of blue eyes.

How did blue eyes originate?

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. … “A genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a ‘switch,’ which literally ‘turned off’ the ability to produce brown eyes,” Eiberg said.

Are blue eyes the result of inbreeding?

However, the gene for blue eyes is recessive so you’ll need both of them to get blue eyes. This is important as certain congenital defects and genetic diseases, such as cystic fibrosis, are carried by recessive alleles. Inbreeding stacks the odds of being born with such conditions against you.

Did Vikings have blue eyes?

Are all blue eyes related?

New research shows that all blue-eyed people share a common ancestor. This person lived more than 6,000 years ago and carried a genetic mutation that has now spread across the world. The exact cause remains to be determined, but scientists do know that eye color began to change long before recorded history began.

Do Indians have blue eyes?

But, since blue or green eyes are rare in India, it’s likely that your husband has two brown alleles in the first gene. If that’s true, then he can only pass on brown alleles for the first gene, and all your children will have brown eyes. … Then your kids could have blue, green, or even hazel eyes.

Where do GREY eyes come from?

Gray eyes are most common in Northern and Eastern Europe. Scientists think gray eyes have even less melanin than blue eyes. Gray eyes scatter light differently, which makes them pale.
