In poultry, feathered legs, F, are dominant over clean legs, f. Pea comb, P, is dominant over single comb, p.
Two cocks, A and B are bred to two hens C and D. All four birds are feathered-legged and pea-combed.
Cock A with both hens produces offspring that are all feathered and pea. Cock B with hen C produces both feathered and clean, but all pea-combed, but with hen D, cock B produces all feathered but three-fourths are pea-combed and one-fourth are single.
What are the genotypes of these birds?
