1, from the genetic point of view, there is a certain scientific basis for nephew to look like uncle. The baby's X chromosome comes from the mother's egg, while the mother's X chromosome and the baby's uncle's X chromosome come from the same parent. That is to say, excluding the factor of genetic variation, the X chromosome carried by the baby is actually half the same as that carried by the uncle.

Generally speaking, a child's father or mother shares 50% of the same genetic factors with the child. So children have 25% of the same genetic factors as uncles or aunts. Therefore, according to genetic analysis, it is not surprising that children look like uncles or aunts.
