Brown, which is the most common eye color in the world. Green, which is the least common eye color.
Every blue-eyed person today is a distant descendant of this one, ancient human. About 27% of Americans have blue eyes, making it the third rarest eye color.
It's a common belief that all babies are born with blue eyes, but this is actually a myth. A baby's eye colour at birth depends on genetics. Brown is also common, for example, but a newborn baby's eyes can range in colour from slate grey to black.
The vast majority of people in the world have brown eyes. The second most common color is blue, but people can also have green, gray, amber, or red eyes. Some people have eyes that are different colors than each other.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
There are plenty of blue-eyed Asians. This probably happens when the traditional blue-eyed allele comes into a family from a (possibly very distant) European ancestor. Blue eyes then resurface in a child generations later if they inherit the allele from both parents.
Blue is the second most common eye color globally, with an estimated 8 to 10 % of people having blue eyes. A majority of these people are of European descent, however, Black people can be born with blue eyes even though it's pretty rare.
Iris color, just like hair and skin color, depends on a protein called melanin. We have specialized cells in our bodies called melanocytes whose job it is to go around secreting melanin. Over time, if melanocytes only secrete a little melanin, your baby will have blue eyes.
There's no guarantee when it comes to your offspring's eye color. While a baby inherits half of their eye color genetics from one parent and half from the other parent, the way that the multiple genes interact also plays a role in determining eye color.
Red/Pink Eyes
Two major conditions cause a red or pinkish eye color: albinism and blood leaking into the iris. Although albinos tend to have very, very light blue eyes due to a lack of pigment, some forms of albinism can cause eyes to appear red or pink.
Complete heterochromia is definitely rare — fewer than 200,000 Americans have the condition, according to the National Institutes of Health. That's only about six out of every 10,000 people. It's currently unknown how rare central heterochromia is, but we do know that it isn't quite as rare as complete heterochromia.
Changes in eye color are rare. Sometimes, the color of your eye may appear to change when your pupils dilate. The colors in your environment, including lighting and your clothes, can give the illusion of eye color change.
How Rare Are Purple Eyes? People with purple eyes make up less than 1% of the world's population. This means purple, or violet, is truly one of the rarest eye colors across the globe.
The second-rarest eye color is hazel, a mixture of brown and green with golden flecks. About 18% of Americans have hazel eyes, compared with about 5% of the world's population.
Why are hazel eyes so rare? Only about 5 percent of the population worldwide has the hazel eye genetic mutation. After brown eyes, they have the most melanin. . The combination of having less melanin (as with green eyes) and a lot of melanin (like brown eyes) make this eye color unique.
“Can two parents with blue eyes have a child with brown eyes?” Yes, blue-eyed parents can definitely have a child with brown eyes.
If both the parents have brown eyes, then there is generally a 25% chance for their child to have blue eyes. Because both the brown-eyed parents have a recessive blue-eye gene and can pass it to the next generation. However, since eye color is polygenic, several other genes exert their effects as well.
Myth: Two blue-eyed parents can't produce a child with brown eyes. Fact: Two blue-eyed parents can have a child with brown eyes, although it's very rare. Likewise, two brown-eyed parents can have a child with blue eyes, although this is also uncommon.
Black hair and blue eyes is a much more rare combination than is blonde hair and blue eyes. The reason why these two traits are linked is that the genes responsible for hair and eye color happen to be close together on the same chromosomes.
The ethnic Miao people of Guizhou province from China, a subgroup of Hmong people, have been described as having blue eyes and blonde hair.
People with blue or light eyes tend to be more sensitive to light. This is because blue eyes, especially light blue eyes, have less pigment in the iris, making them more translucent. This can cause blue-eyed people to be more susceptible to glare and sunlight, leading to light sensitivity.
In Asia, red hair can be found among some peoples of Afghan, Arab, Iranian, East Indians, Mongolian, Turkic, Miao, and Hmong descent. Several preserved samples of human hair have been obtained from an Iron Age cemetery in Khakassia, South Siberia.
Blue eyes are a fascinating and unique trait that can be found in many different parts of the world. Approximately 8% of the global population has blue eyes, with higher concentrations in certain countries such as Lithuania (95%), Finland and Estonia (89%) or the United States (16.6%).
Very dark brown hair, easily mistaken for black hair, can be found occasionally in parts of East Asia.
