Blue Brown 50%

Did blue eyes come from inbreeding?

They report that a mutation just 6,000 to 10,000 years ago, by necessity in just one person, explain all the blue eyed people on the planet. (Of course, the recessive gene had to carom about, with a kiss of incest, in some small clan until double copies came together to make a blue-eyed person).

Where did blue eyes originate?

“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.

Are blue eyes a defect?

Scientists have tracked down a genetic mutation which took place 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today.

What country has the most blue eyes?

Blue eyes are most common in Europe, especially Scandinavia. People with blue eyes have the same genetic mutation that causes eyes to produce less melanin. The mutation first appeared in a person living in Europe about 10,000 years ago.

Can 2 blue eyes make a brown eyed baby?

Eye color is not an example of a simple genetic trait, and blue eyes are not determined by a recessive allele at one gene. Instead, eye color is determined by variation at several different genes and the interactions between them, and this makes it possible for two blue-eyed parents to have brown-eyed children.

How do you know if you carry a blue eyed gene?

The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.
