Suppose we have “GeneA.” The resulting polypeptide of “Gene A”influences the hardness of claws in a species of pocketgopher. These burrowing mammals use their claws to digthrough the soil. Soft claws are useless for digging andgophers with soft claws soon die.

There are two alleles for“Gene A,” A and a. Gophers homozygous dominant(AA) and heterozygous (Aa) for this gene have hard claws and digjust fine. Gophers homozygous recessive (aa) have soft clawsand die.

Use what you know aboutMendelian genetics to predict the frequency of the three a for ementioned genotypes in a population in Hardy-Weinbergequilibrium where the allele frequencies are A = 0.5 and a =0.5.
