Determine the genotype of offsprings in a cross between normal male and female cockroaches.

Explanation

In case o of corkroach, the males have odd sex chromosomes (AA+X) whereas the females, have two homomorphic sex chromosoems (AA+XX). The male cockroach is heterogametic and produced two types of gemetes, i.e., A+X and A+O. The female cockroach is homogametic and produced only on type of eggs., i.e.,A+Y, The porgeny is obtained in the ratio of 50 males : 50 females. The genotype of offsrpings is 50% AA+XX and 5% Aa+XO.
