Apart from the features mentioned in the story above, there are also claims that this mutation results in highly evolved immune system that gives the person a long life span (ranging from 130-170 years). The stories of Alexandria’s Genesis have been quite popular for many years now, describing it as a rare, genetic mutation with fascinating and impressive characteristics that follow after eyes turn Purple. Alexandria’s Genesis, a Rare Genetic Mutation Analysis: No body knows if its real, but its pretty cool. Other VersionsĪlexandria’s Genesis (aka people with purple eyes). Women with this condition are fertile but do not menstruate. Those that have this mutation are said to never grow pubic, facial, body or anal hair excluding that on the top of their head, ears, eyebrows, eyelashes and noses. During puberty, the color deepens to a royal or violet-blue purple and remains that way, but will not affect the person’s ability to see. Due to her recessive gene, now and then a child is born in the area with bright blue eyes.Alexandria’s Genesis or violet eyes is considered a genetic mutation that causes the eyes to turn from blue or gray to purple for the following six months. She became the wife of a Prince and started a dynasty that extends into many of today’s Xhosa royal families. In the 1730s, a seven-year-old English girl washed up on the shores of West Africa and was adopted by her rescuers. It’s really surprising to know you can find people with blue eyes in Africa. In Germany almost 75% of the population have blue eyes. The countries where you can find the most blue-eyed people are Netherland, Germany, the Baltic States, and Scandinavia. Blue eyes are common among Israeli Jews, the percentage of people with blue eyes is decreasing in the US. Professor Eiberg explains that it is nature who is continuously and constantly shuffling the human genome thereby creating a cocktail of human chromosomes trying out changes.īlue eye color is the second rarest color after green. The mutation of brown eyes to blue ones does not represent a positive or negative mutation, it’s like many other mutations including baldness, hair color, freckles, and beauty spots, none of which affect chances of survival. Nature is responsible for the shuffling of genes. Research began in 1996 when Professor Eiberg suggested the theory of the OCA2 gene as responsible for eye color. He and his team examined mitochondrial DNA and analyzed and compared people who had blue eyes in countries like Jordan, Denmark, and Turkey. The findings of Professor Eiberg and his team are the latest regarding genes. All blue-eyed people have a small amount of variation in the amount of melanin in their eyes, leading to the conclusion that all blue-eyed people have a common ancestor and have the same switch inherited at the same place in their DNA. Variation in eye color from brown to green is linked to the amount of melanin present in the iris. If there were no melanin then we all would be without colors in our hair, eyes, and skin, a condition known as albinism. The switch is situated in the gene adjacent to OCA2 and does not entirely switch off the gene but limits its function to reduce the production of melanin in the iris – effectively diluting brown eyes to blue. Melanin is the pigment that gives color to hair, eyes, and skin. The OCA2 is a gene that codes for P-protein, responsible for the production of melanin. A genetic mutation affected the OCA2 gene in our chromosomes which created a switch that literally switched off the ability to produce brown eyes. They found a genetic mutation that took place between 6000 – 10,000 years ago which is the reason behind the occurrence of blue eyes and the causation of all blue eyed people today.Įiberg, a professor of the Department of Cellular and Molecular Medicine, says we all had brown eyes originally. The research showed that those who have blue eyes have a single common ancestor. A team at University of Copenhagen conducted a study in 2008 about the formation of blue eyes.
