The presence of feathers on the legs of chickens is due to a
dominant allele (F) and clean legs to its recessive allele ( f).
Pea comb shape is produced by another dominant allele (P) and
single comb by its recessive allele (p). In corsses between pure
feathered leg, single-combed individuals and pure pea-combed,
clean-legged individuals, suppose that only the single-combed,
feather-legged F2 progeny are saved and allowed to mate at random.
What genotypic and phenotypic ratios would be expected in F3?
