The chances of having black hair and blue eyes are 1 in 500. But there’s good news. The chances of having black hair and blue eyes are still better than having brown hair and green eyes.
Chromosomes – DNA – Eggs – Sperm Why is dark hair and blue eyes rare? Why do Irish have black hair and blue eyes? Which ethnicity is black-haired and blue-eyed from
We all have forty-six chromosomes that come in pairs. Eggs and sperm each have 23 single chromosomes so that when they combine, you get 23 teams again. You get divided evenly half from mom and half from dad. When a child is born, there is almost no pigment in the iris, so the eyes are blue.
- Between 6-36 months, cells in the iris start producing melanin, causing the eyes to change color.
- Too much melanin will make the eyes brown or black and not enough malanin and the eyes remain blue.
- Many African and Asain children are born with brown and black eyes, but there are some that are born with blue eyes.
There are many people in the world that will dye their hair or wear colored contacts to achieve the black hair blue eyed look. There’s no known reason why having black hair and blue eyes are rare. However, several factors could be why black hair and blue eyes are rare.
- First, they’re often the result of recessive genes.
- Although humans indeed have the same pair of human genes that determine skin tone and eye color, 5 to 10 percent of the population has the black-brown and blue-green genes.
- Second, having blue eyes can likely be explained by a recessive gene in the recessive gene pool.
For instance, in Europe, around one in 10 males and one in 15 females have brown eyes and red hair. For this reason, many people with brown eyes have a slight tendency also to have brown hair. What about black hair and blue eyes? Why do some people have black hair and blue eyes? The answer is simply the same as the reason why some people have brown hair and blue eyes.
The fairer your skin tone, the more likely you are to have brown hair and blue eyes. This is because when soft-skinned babies are born, there is more pigmentation in their iris. So you end up with more brown eyes and less blue eyes. But why do some people have black hair and blue eyes? Again, the answer is the same as why some people have brown hair and blue eyes.
A gene is a genetic material responsible for producing an observable physical trait. And the brown and blue eyes gene is recessive. So if you have this gene, you have black hair and blue eyes. Typically, black-haired and blue-eyed people are considered black or African-American.
- Blue-eyed people are categorized as being white.
- The same holds for blue-eyed people who are also of African descent.
- However, a small percentage of people have a combination of both black and blue eyes.
- People with a lighter complexion who are also of African descent are more likely to have this combination of features.
These people are known as Deaf-mute, While this is a tiny percentage of people, studies have shown that Deaf-mute people also tend to have a lighter skin tone than black people. Other studies have discovered that people with blue eyes of African descent are more likely to have African skin tones.

Is being black with blue eyes rare?
I am an African-American. Why do I have blue eyes? African-Americans with blue eyes are not unheard of, but they are pretty rare. There are lots of ways for this to happen. Some possible ways an African-American person might have ended up with blue eyes are:
Caucasian relatives in their ancestry (the most likely reason)A rare disease that causes albinism only in the eyes (ocular albinism)A new mutation that makes their eyes blueWaardenburg syndrome (A common way to end up with two different colored eyes.)
What is the most rare hair and eye color?
The rarest hair and eye color combination – What are the rarest hair and eye color combinations? That’d be red hair with blue eyes. There’s a little genetic tweak that makes the combination of red hair and blue eyes the rarest of them all. The same Nature study mentioned above found that another gene variant, HERC2, interacts with both the MC1R gene and the OCA2 gene—and it can shut off the redhead gene while expressing blue eyes and blonde hair.
- That makes the blue eye and red hair combination even more unlikely to happen.
- In addition, with both red hair and blue eyes being something akin to recessive traits, having parents that are able to pass on two sets of recessive genes is very unlikely.
- In most cases, you’d have blue eyes and hair somewhere on the spectrum of blond to brown, or red hair with brown, hazel or green eyes.
According to an article by evolutionary biology professor Mark Elgar, PhD, of the University of Melbourne, blue-eyed redheads are the absolute rarest, with 0.17% of the population having that combination of hair and eye color. So if that describes you, you’re most likely one in a million (or more!).
