have before fertilization?
A. The egg and sperm each have 30 chromosomes, because the fertilized egg receives one set of chromosomes from each parent.
B. The egg has 20 chromosomes and the sperm has 10, because eggs are larger and therefore provide more chromosomes during fertilization.
C. The egg has 40 chromosomes and the sperm has 20, because eggs are larger and therefore provide more chromosomes during fertilization.
