There is another question also, why do we not look exactly like our parents or siblings even though we inherit genes from our parents?

After all, kids get their genes from the same parents. But brothers and sisters don't look exactly alike because everyone (including parents) actually has two copies of most of their genes. And these copies can be different. Parents pass one of their two copies of each of their genes to their kids.
