In chickens, the presence of feathers on the legs is due todominant allele (F) and the absence is due to recessive (f). Apea-shaped comb on the top of the head is controlled by a dominantallele (P) and a single comb by the recessive allele (p). A crossis made between a chicken that is true breeding for feathered legsand a single comb and a chicken that is true breeding for theabsence of leg feathers and pea comb. Only the single-combed,feather legged F2 progeny are saved and these birds are allowed tomate at random. What genotypic and phenotypic ratios are expectedamong the progeny?
P: F/F ; p/p x f/f ; P/P
F1: F/f ; P/p
So, I know the F2 can be F/f ; p/p or F/F ; p/p but how do Igo about finding the ratios?
