Question

Considering epistasis in cattle, there is a gene that allows horns to be either beaded or smooth. There is a second gene that controls the production of the protein that allows horns to be formed. If a cow can make no horns, it is called a polled cow. Cross a beaded horned cow that is heterozygous at both sites times a smooth horned cow that is heterozygous for protein production. Show me the genotypes of the P1 and the genotypes and phenotypes of the F1. Of the F1 cattle, cross one of the beaded cows times one of the polled cows so you make sure you see the most polled cows as possible in the F2.
