Why some have brown and black eyes, some blue? Know the science behind the different colors of the eyes

Eye Colour: It is human nature that whenever we meet someone for the first time, the first thing we do is eye contact. When there is eye contact, the first glance goes to the colour of the eyes. Normally, everyone's eyes are either black or brown, but we also meet some people whose eye colour is different from others, such as those with green, blue, and kanji eyes. Many times we are attracted by the people of these unique eye colours, so many times the question arises in our mind what is the reason behind this different colour? Is having different eye colors a sign of beauty? Many questions start arising in our minds. Many times we are also forced to think that why the colour of our eyes is not so unique. If similar questions also arise in your mind, then today through this article we will answer you, what is the reason behind the different colours of the eyes?

Because of this, the colour of the eyes is different.
The color of our eyes is related to our genes. The color of our eyes is determined by the amount of melanin in our pupils. Apart from this, the color of the eyes also depends on the density of the protein and the first light around. If there is less melanin in the body, then the color of the eyes is green or blue. While the color of the eyes is brown or black when the amount of melanin is high.

These genes are responsible for the different color of the eyes
There are two major genes responsible for eye color and they are OCA2 and HERC2. Both of these are present in chromosome 15. HERC2 is thought to be responsible to a certain extent for blue eyes while OCA2 is associated with blue and green eyes. It is believed that the ancestors of blue-eyed people are the same, about 6 thousand to 10 thousand years ago, due to a change in human genes, the color of the eyes of people became blue.

The largest population of brown eyes in the world
According to a report, 79 percent of the population has brown eyes, which is considered the most common eye color, after brown, 8 to 10 percent of the world's people have blue eyes. The reason behind this is that most people have such developing genes, 5 percent of people with hazel eyes are involved. Whereas the number of people with blue eyes is the least in the world. According to scientists, the color of our eyes can change very rapidly in the early stages of life. Many times it happens that children are born with blue eyes, but later the color of the eyes becomes brown.
