The image shows the process that forms sperm and ovum in humans. Both sperm and ovum begin from parent cells that contain 46 chromosomes.



A sperm fuses with an ovum during fertilization to form a zygote that grows into an organism. How does fertilization help in reproduction.
B It ensures that the genetic material of the zygote and both parent cells is identical.
It ensures that the zygote has double the number of chromosomes as the parent cells.
C It ensures that the zygote has the same number of chromosomes as the parent cells.
D It ensures that the genetic material of the zygote and both parent cells is replicated.
