Brown to blue eyes

Contact Us Diversity Training: Brown Eyes, Blue Eyes "Brown eyes, blue eyes" is the name often given to an anti-discrimination experiment that was carried out in America in It was conducted in a small school in Riceville, Iowa, amongst 8-year-old children on the day after the assassination of Civil Rights leader, Martin Luther King. The experiment was devised by the children's teacher, Jane Elliott, as a way of explaining why King had been murdered and what it felt like to be discriminated against.

Contact Author People pay very little attention to common eye colors, which explains why I get little to no compliments on my big brown eyes.

We tend to be captivated by rare traits or unusual combinations, such as black people with blue eyes. This article will cover the origins of black people with blue eyes, and will list some examples of well-known black celebrities with Brown to blue eyes eyes.

Yes, you can be black and have blue eyes. Still, blue eyes are very uncommon among black people, especially those with no Caucasian ancestry. Research has found that almost everyone with blue eyes is linked to an ancient genetic mutation, and a small fraction get their blue eye color as a result of a health condition such as ocular albinism, which affects the pigmentation in the eye.

In short, the origin of black people with blue eyes is no different than the origin of any human's eye color, the deciding factor being genetics. Research argues that, at one point in time far in the past, everyone on the planet had brown eyes.

The first light-eyed human emerged only about 10, years ago, says Professor Hans Eiberg and his team of Danish scientists from the University of Copenhagen.

Can You Be Black and Have Blue Eyes?

In their studyEiberg and his team recruited blue-eyed men and women across different countries. They studied the genes that coded blue eyes in all of these individuals.

They were able to conclude that all blue-eyed people have the exact same DNA sequence to account for their blue eyes. They also found that this DNA sequence contains an ancient genetic mutation which presumably occurred 10, years ago around South-Eastern Europe.

In other words, blue-eyed celebrities Matt Damon and Elijah Wood are your distant cousins if you have blue eyes. Everyone with blue eyes is related in a distant way. Black people are affected by this genetic mutation in the same way any other human is, but because the mutation originated in Europe, it is rare to see a black baby born with blue eyes.

We will explore this concept more in the sections below. Another, but less common, reason why a black baby may be born with blue eyes is if it has ocular albinism or waardenburg syndrome.

People with blue eyes are affected by a genetic mutation that turns off their ability to produce brown eyes. The mutation that gave rise to blue eyes altered the OCA2 gene, a gene that codes for the production of the brown pigment melanin in our eyes. The result is very little melanin production in the iris of the eyes, and the low melanin concentration, being insufficient to produce brown eyes, produces blue eyes2.

For 10, years, the blue-eye gene has been passed on from parents to offspring and has spread to different geographical regions. A descendant often has blue eyes if he or she inherited the right set of genes from both parents, and it is believed that almost every blue-eyed person on earth today inherited the same mutation from the same source.

A tiny fraction of blue eyes are caused by health conditions such as waardenburg syndrome and ocular albinism. These conditions are characterized by pigmentation problems, and can affect as many as six different genes responsible for eye color.

These health conditions impact the growth and development of pigment-producing cells, and can potentially lead to a much lower pigment concentration than in the case of the OCA2 mutation, producing brighter almost white blue eyes.Two brown-eyed parents (if both are heterozygous) can have a blue-eyed baby.

B y these rules, i t would seem that two blue-eyed parents cannot have a brown-eyed baby because blue-eyed people are homozygous.

Also, some people (like me) start off having blonde hair as children and then it gets brown as they age. Some people, however, have brown hair and blue eyes from birth and their hair color doesn’t change much.

Brown-eyed children, meanwhile, were forced to sit at the back of the class and were more severely reprimanded for the same type of behavior that blue-eyed children got away with.

Elliott even made up a scientific 'fact' that the melanin that caused blue eyes had been found to be linked with a higher intelligence. Brown-eyed people have more melanin, less light. The opposite is true for people with "blue" eyes.

What Is the Origin of Black People With Blue Eyes?

Those with less melanocytes can't absorb as much light, so more light is reflected back out of. Melanin, she said, is what causes intelligence. The more melanin, the darker the person's eyes—and the smarter the person. "Brown-eyed people have more of that chemical in their eyes, so brown-eyed people are better than those with blue eyes," Elliott said.

"Blue-eyed people sit around and do nothing.
