Question

Through your contacts in the international zoo-keepers society, you learn that the Wakanda zoo has a black cougar named T'Challa (please note that cougars are sometimes also referred to as Panthers). Excited at the potential of a fourth allele, C⁴, you write to your Wakandese colleagues asking for a sperm sample. You use T'Challa's sperm to fertilize both a C¹C¹and aC²C²female. Both females produce large litters of cubs, 100% of which are black. Curious as to the molecular nature of C⁴, you also perform a biochemical analysis. You discover that the enzyme encoded by C⁴ catalyzes the same biochemical reaction as C¹,but at 100 times the rate. Hair follicles are therefore saturated in brown pigment and appear black. Which of the following can be concluded about the C⁴ allele? Select ALL that apply.

		It is a hypermorph
		It is always dominant
		It is dominant to C2
		It is a gain-of-function allele
		Wakanda forever
		It is a neomorph
		It is dominant to C1

Answer 1

The C4 allele is hypermorph ( as the allele is having greater effect than the corresponding wild type allele C1) and always dominant to C1 allele.
