Answer:
Genes are transferred from parents to offsprings by inheritance. Each offspring receive half of their genes from mother and half from father. But answer of this question is:- Each offspring receive not exactly the same halves of the genes. This different halved of the genes are the reasons we don't.
Step-by-step explanation:
The only example is with step parents, or others. Half of the parental genes are passed to the child, so a chance for one to look like the uncle or aunt of the family is high. It can also look like any before them, such as a grandmother, father, great grandmother, etc.
