How does sexual reproduction play an important role in variation?
A. Production of unique gametes during meiosis, and the random combination of male and female gametes upon fertilization provides a large amount of
variation.
B. Male and female gametes combine randomly during fertilization, and then each gamete randomly selects half of its DNA to give to the embryo.
C. Implantation into the uterus provides the embryo with DNA from the mother to create more variation.
D. Sexual reproduction is not related to variation.
