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

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?
