Is it normal for a child to not look like his father?

After a child is born, parents are very happy and hope to grow up with their children and face future difficulties and happiness together. But many people wonder why their children don’t look like themselves? Although they are very sure that both husband and wife have not engaged in any other deviant behavior, they still cannot explain the fact that the child does not look like themselves, and it may even make many people sad. So why don't children look like their fathers?

One is inheritance from the previous generation. Although children's appearance mainly comes from their parents, parents' appearance also comes from their respective parents. Therefore, there is a possibility of inheritance from the previous generation, and it may even need to be traced back to more than several generations. A white couple in Australia gave birth to black and white twins. The fundamental reason was that one of the couple (Ding Ding couldn't remember which one) had a black ancestor.

The second is to take on the recessive traits of one or both parents. Some children appear to look like neither their father nor their mother. In fact, it is because the child has inherited the recessive traits of both parents. If we do not observe carefully, we cannot see that the child's parents have such traits because the other traits they show are too strong and cover up the other traits. Their children happen to inherit these recessive traits. Therefore, children with a handsome father and a beautiful mother may also give birth to relatively ugly children, or ugly parents may give birth to handsome or beautiful children.

Any embryo is formed from the union of a sperm and an egg. Each sperm contains only 23 chromosomes, carrying the father's genetic material; each egg also contains 23 chromosomes, carrying the mother's genetic material. The fertilized egg formed by the combination of egg and sperm has 46 chromosomes, half from the father and half from the mother. Because chromosomes are the carriers of genetic material, there are more than 2,000 genes on each chromosome. The human body has about 50,000 structural genes, and the genes that carry various human traits come from parents, so children look like their parents.
