The dorsal pigment pattern of frogs can be either leopard or mottled. The trait is controlled by an autosomal gene. Males and females are selected from pure breeding populations, and a pair of reciprocal crosses is performed. The cross results: Cross 1: P: Male leopard  female mottled F1: All mottled F2: 70 mottled, 22 leopard Cross 2: P: Male mottled  female leopard F1: All mottled F2: 50 mottled, 18 leopard

a. which of the phenotypes is dominant. Describe your answer

b. compare and contrast the results of the reciprocal crosses in the context of autosomal gene inheritance

c. in the F2 progeny from both crosses, what proportion is expected to be homozygous? what proportion is expected to be heterozygous

d. propse two different genetic crosses that would allow you to determine the genotype of one mottled from the F2 generation
