As a student of genetics, you become interested in the phenotype of feathered legs in Black Langshan fowl and featherless legs found in Buff Rocks fowl. Your first inclination is that this trait is controlled by a single gene - two allele genetic system. To test this hypothesis you mate a true breeding Black Langshan with a true breeding Buff Rocks, and all of the offspring develop feathered legs. Reciprocal crosses yielded the same results. Using an allele system of your choice, describe this cross.

**Breeding Experiment Analysis** After your first breeding experiment, you become more convinced that you are dealing with a single locus system with one allele showing complete dominance over the other allele. Continuing the breeding study, you breed two of the F₁ birds. Given your working hypothesis, what are the expected proportions/ratios of F₂ genotypes and phenotypes in this cross?
