The color of individual people is different. Someone's black, some blue, somebody or brown. Explaining the matter, Editor of Kerala Journal of Scientific Research and Review. Cyanidine stone
The color of the eye is determined based on the amount of melanin in Irish, the density of the protein, and the irregular part of the strings of the strings in Iris.
The amount of pigment in the name of the melanin material is determined again on the proportion of eomelanin and foomelinin. The eye color is divided into 9 categories. There are 16 genes working to determine the color of the eye.
Genetically the most dominant genes for determining eye color are OCA 2 and HERC 2. Their positions are in chromosomes 15. Generally, the HERC 2 gene can be blamed for blue eyes. And OCA 2 usually works in creating blue and green colors of the eyes.
But globally, the eyeballs are the most common. From the very beginning of the human civilization, this color prevails. On the other hand, the blue eyes largely survive in genealogies and are becoming rare day by day.
Experts believe that genetic mutations in blue eyes were created from 6 thousand to 10 thousand years ago. Blue eyes look darker than dark eyes. Because the color of melanin pigment is very much in color. Irish gray color is formed based on melanin and protein intake. Only two percent of the world's people have green eyes. Melanin is very rare in this eye. Light brown color is actually the most light blue and dark brown mix. In light brown color eyes there is a large amount of melanin stored along the Irish border.
According to scientists, dramatic changes can occur in the eye color during the first few years of life. Many babies grow with blue eyes. But later it becomes green or brown.
