Why is a son more like a mother?

We are used to discussing who is more alike when the baby is born. We have to say that consanguinity is a wonderful thing, which allows you to recognize the consanguinity between you and your children from the outside. It is said on the Internet that boys are more like their mothers in intelligence, height and skin color, but many examples in real life tell us that this is not the case.

1. Although there is a theoretical basis, the fact is only a probability event.

In fact, the reason why boys are like mothers is because this statement has its genetic and physiological basis. The chromosome composition of a boy is x y, where X comes from his mother and Y comes from his father. The baby girl is the XX chromosome, which comes from both parents. Because both ends of X chromosome are longer than Y chromosome, which is more advantageous in expression, there is a saying that boys are more like mothers.

These are all theoretical statements. In fact, many genes in our body are not expressed, or expressed in a randomly selected large gene pool, which will lead to the emergence of alternative genes or some new features, such as two fair-skinned parents giving birth to a dark-skinned baby. In this way, the baby boy will be more like the mother.

There are many environmental factors.

In addition to heredity, the environment often has a great influence on children's personality. Under normal circumstances, insufficient nutritional supplement has little effect on children's height, height and fatness. Adolescence, only timely nutrition, in order to have the ideal height, rather than the height of parents, the efforts of the day after tomorrow can not be changed. The two complement each other, especially fat and thin, so it is also important to exercise more and eat more nutrition.

There is also a saying that children's intelligence is more like their mothers' intelligence and needs to be studied. It is said that some foreign scientists have done research. The conclusion is that the genes affecting gene development are located on the X chromosome. But now most of us are at the same level of intelligence.
