Allen and andrew have the same biological parents. why do they not resemble either of their parents? a) each child receives only paternal genes. b) each child receives only maternal genes. c) each child receives only half of each parent’s genes. d) each child receives genes from only one of the parents.

C. when parental units form reproductive cells, the source cells undergo meiosis and split into four gametes, each containing half of the original cell's genetic information (the split happens haphazardly so no two gametes are the same). Thus, each fertilized egg contains equal amount of genetic information from each parent.
