Human eye color is genetic

We will find that foreigners have blue eyes, and their babies are born with blue eyes, while Chinese people have black eyes, and their babies are born with black eyes. In fact, the heredity of eyes exists, but there are different conclusions as to whether the eyes are passed on to the mother or the father, and special attention needs to be paid.

The influence of the shape of parents' eyes on their children is obvious. People often say to a child, "His eyes look exactly like his mother's." Yes, eye shape is hereditary, and big eyes are dominant over small eyes. This is undoubtedly a happy thing for people with small eyes. No matter what they are like, as long as their spouse has big eyes, the possibility of their children having big eyes is greater.

Although people have different standards for beautiful eyes in different eras, most girls always want big, bright eyes with double eyelids. If you are born with single eyelids, don’t worry too much, maybe it will change! According to statistics, only 20% of infants have double eyelids, 40% of middle school students, and about 50% of college students.

Eye color is also something people like to talk about. The color of white people is blue and brown, and the color of yellow people is black and brown. The inheritance of eye color follows the rule that dark colors such as black are dominant over light colors. That is to say, if you envy blue eyes, even if you choose a lover with blue eyes, because you have black eyes, your child will unfortunately not have blue eyes (actually in terms of functionality, black is more advantageous than blue and brown).

Long eyelashes not only keep out the dust, but also make the eyes vivid. Long eyelashes are also dominant!
