Which of the following scenarios best describes an epistatic gene? Select one: a. Fur pattern is controlled by two genes such that one gene inhibits the expression of the other gene. b. Chicken combs follow a dominance hierarchy whereby a walnut comb is the most dominant and a single comb is the least dominant. c. Individuals with sickle cell anemia and carriers of the sickle cell allele have some resistance to malaria. d. Mouse fur colours are expressed as a blend of the dominant black colour and the recessive white colour, resulting in a heterozygous brown colour.
