The issue of having a boy or a girl is definitely the most talked about topic among many mothers who want to have a baby. Some people may say that having a boy or a girl depends on male friends, while others may say that having a boy or a girl is hereditary. So is there a genetic predisposition to having boys and girls? Dear expectant parents, hurry up and take a look.
In fact, giving birth to boys and girls can be said to be dominated by male sperm, and giving birth to boys and girls is not something that can be controlled or changed by people's will. So the claim that giving birth to boys and girls is hereditary is unscientific and there is no data to prove it. Some people may think that there will always be some similarities between parents and children, and these similarities are called genetics.
In fact, at the moment of fertilization, the egg is in a passive state, and everything is determined by the sperm. Therefore, giving birth to male or female depends on the male sperm. The most important factor in the development of a fertilized egg, whether it grows into a male or female fetus, is whether the sperm and egg combine in a Y-shaped or X-shaped manner.
However, data research has shown that Y-shaped sperm have a higher chance of combining with eggs than X-shaped sperm. Therefore, when 100 girls are born, there will also be 106 boys born at the same time. However, boys are more prone to premature death compared to girls. Therefore, when they grow up to a certain age, the proportion of male and female population is still relatively balanced.
