Chromosomes - DNA - Eggs - Sperm
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.
Why is dark hair and blue eyes rare?
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.
Why do Irish have black hair and blue eyes?
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.
Which ethnicity is black-haired and blue-eyed from
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.
