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. The affected are also said to live up to one hundred and fifty years yet on the other hand the highest reported age to be attained is only one hundred and twenty two years.A team at University of Copenhagen conducted a study in 2008 about the formation of blue eyes. Some traits said to come with the condition are impossible physiologically for example failure to produce waste would cause death due to toxin accumulation in the body, burn resistant fair skin is impossible too since melanin that protects the skin also darkens the skin. The characteristics of the condition are quite widespread for them to be from one gene thus they would have to be from a wide variety of unrelated genes. but there isn’t proof that the condition is there today. There might be a genetic variation causing light skin, purple eyes, good health etc. Who knows? It might be true! Some races are also known to have a high immune system whereas there are people with high metabolism rates, extra good eyesight and do not gain weight easily. Claims of people being affected with the condition have existed for a while. Many say that purple eyes can only be obtained by having this disorder. Generic variance causing the condition was first discovered in 1960s. A child named Alexandria with purple eyes was born who later on gave birth to girls with the condition they lived over one hundred years. The first report of the condition appearing is said to be in 1329, England. The affected people were then considered the spirit people who went to the North and later on disappeared. Legend has it that this condition originated a millennium ago in Egypt a mysterious light is said to have flashed over the sky and whoever saw it developed purple eyes and pale skin. The condition is said to affect mostly people with black or blue hair and Caucasians and to some extent interracial people. They are also immune to a lot of diseases. The affected are said to stop aging at around fifty years and be able to reach one hundred and thirty years to one hundred and fifty years not gain extra weight and retain a perfect figure no matter their level of food consumption. Women are the purported carriers of this mutation. Some sources say that the condition results in skin immune to tanning and burning and is shimmering and white in nature. It is also said that women with this mutation do not menstruate and are ironically fertile. Individuals with this mutation are said to not grow facial, body, pubic or anal hair other than the hair on their head. It however does not affect one’s ability to see. The eye color is said to tend to deepen to a permanent violet-blue or royal purple during puberty. Alexandria Genesis (also known as violet eyes) is purported to be some kind of genetic mutation it is characterized by the individual’s eyes turning purple from gray or blue approximately six months after birth.
