Have you ever wondered how the color of eyes?
Eye color enhances the beauty of any person. For example, if someone's eye color is brown or blue, then his beauty becomes even more beautiful. Eye color also depends on the person's genes. Blue, brown, green and other colored eyes show how the color of the eyes is due to heredity and pigmentation. Let's know this interesting fact about eyes.
Reason for different color of eyes
Let us tell you that the amount of melanin is of special importance in determining the color of the pupil of the eyes. Melanin also plays a big role in determining the color of our skin and hair. Melanin is a pigment which is present in various forms and proportions inside every person. If melanin is less, then the color of the eyes becomes blue. On the other hand, if it is more, the color of the eyes becomes brown and black. Apart from this, the color of the eyes also depends on the density of protein and the surrounding light. Apart from this, genes also play a big role behind different eye colors. OCA2 and HERC2. Both of these are present in chromosome 15. They are also considered responsible for the color of the eyes.
OCA2 gene: This gene plays a special role in the color of the eyes. This gene controls the amount of melanin in the iris. Melanin is a pigment that determines the color of skin, hair and eyes. High melanin content turns the eyes into dark colors such as brown or black, while low melanin is responsible for blue or green eyes.
HERC2 gene: This gene controls the functioning of the OCA2 gene and plays a special role in the color of the eyes. Different versions (alleles) of the HERC2 gene affect the chromosomes of blue or brown eye color.
