The same DNA sequence in the region of the OCA2 gene among blue-eyed people suggests they may have a single common ancestor.
As of 2016, the earliest remains of Homo sapiens with genes for both light-pigmentation and blue-eyes were found in 7,700 years old Mesolithic hunter-gatherers from Motala, Sweden..
Who has stronger genes mother or father?
Genetically, you actually carry more of your mother’s genes than your father’s. That’s because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.
Which race has the most blue eyes?
The blue eye phenotype is most common in the European Caucasoid race, especially among those from North-West Europe. For example in Denmark (Scandinavia) , approximately 50.9% of the population have blue eyes! A brown-haired and blue-eyed Danish person.
Are blue eyes a European trait?
Scientists concluded that every blue-eyed person on the world today can trace their ancestry back to a single European who probably lived about 10,000 years ago in the Black Sea region and who first developed a specific mutation that accounts for the now widespread iris coloration.
Are blue eyes from 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.
What is the rarest eye color in the world?
GreenGreen eyes are the rarest color. Brown eyes are the most common. People can also have blue eyes, (Learn More) gray eyes, (Learn More) or hazel eyes.

Since there are 7-8% of people worldwide with blue eyes, the percentage with blue eyes and brown hair should be somewhere in the low single digits, maybe 3-5%.
Where do blue eyes originate from?
“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 from Vikings?

Can 2 brown eyes make a blue eyed baby?
The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby.
Are blue eyes special?
Blue-eyed people are more sensitive to light. Ophthalmologists believe that people with blue irises tend to be more light-sensitive. Because blue eyes don’t have enough light-absorbing pigment, more light can get through the iris and damage the eye.
Why are blue eyes so rare?
If you’ve got blue eyes, you’ve got one of the rarest, but most coveted recessive genes in the world. … The way blue eyes develop is even rarer than the eye color itself, however. Scientists have discovered that a genetic mutation on the OCA2 gene changes the body’s pigment production, creating blue eyes.
Where do blue eyes come from Mom or Dad?
But if only one of you has a recessive blue-eye gene, and the other has two brown, dominant genes, then there is a less than 1% chance of the baby having blue eyes. Each person carries two copies of every gene, one copy inherited from mom and one inherited from dad.
Who is famous for blue eyes?
2. Paul Newman. Notable achievements: American actor, producer and philanthropist Paul Newman has some of the most famous blue eyes the world has ever seen.
Are blue eyes the rarest?
Between 8 and 10 percent of people worldwide have 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.
