In chickens, comb shape is determined by genes at two loci (R, r and P, p) .A walnut comb is produced when at least one dominant gene R is present at one locus and at least one dominant gene P is present at a second locus (genotype R_ P_) .A rose comb is produced when at least one dominant gene is present at the first locus and two recessive genes are present at the second locus (genotype R_ pp) .A pea comb is produced when two recessive genes are present at the first locus and at least one dominant gene is present at the second (genotype rr P_) .If two recessive genes are present at the first and the second locus (rr pp) , a single comb is produced.Give genotypes for comb shape of the parents in the following cross: rose crossed with single produces 31 rose offspring.
