Use the following information for the next 2 questions. Pigeons have two alleles of a single gene that determines whether they have feathers on their lower legs. The alleles are called no grouse (associated with the featherless phenotype) and grouse (associated with feathery legs). Suppose a pigeon that is homozygous for the no grouse allele mates with a heterozygous pigeon. What is the expected frequency of the homozygous no grouse GENOTYPE in the offspring?
