Why does the baby look like his father when he is born and become like his mother when he grows up?

I don't know if you treasure moms have noticed that when babies are born, they are almost the same, with swollen eyes, chubby faces and tender skin. It's hard to say whether they look like their father or mother. In fact, that's because we are not familiar with newborns, and we can only see the difference after watching more. Almost all babies will be born like their father or grandfather. This is an instinct of self-protection. The newborn baby declared to his father in his own appearance: I am your child, and asked his father to take up the responsibility of raising me. As the baby grows older, the baby's appearance will change, that is, it will gradually become like a mother.

In ancient times, it was a patriarchal society and attached great importance to whether children were their own. When you first see a child and feel different from yourself, you may feel that your wife is unfaithful to you, and then you will divorce your wife, which will have a particularly bad influence on your mother. Therefore, instinctive reasons will make children more like their fathers when they are born. This can reduce unnecessary family disputes and make a family harmonious.

Once the father confirms that the child is his own, he will relax his vigilance and the child will gradually have the characteristics of the mother. That's why children look like their father when they are born.

Everyone knows that having a baby is determined by two chromosomes, XX for girls and XY for boys. One of these two chromosomes comes from the mother and the other from the father. Who does the baby look like? It depends on whose genes are dominant. If the father's genes are dominant, then the baby will look like his father, but if the mother's genes are dominant, then the baby born will look more like his mother.

So from this perspective, the chances of a newborn baby being like a father or a mother are the same, both being 50%. This is also a more scientific explanation.
