Consider three yellow, round peas, labeled A, B, and C. Each was grown into a plant and crossed to a plant grown from a green, wrinkled pea. Exactly 100 peas issuing from each cross were sorted into phenotypic classes as follows

A:        51 yellow, round

            49 green, round

B:      100 yellow, round

C:  24 yellow, round

      26 yellow, wrinkled

      25 green, round

      25 green, wrinkled

What were the genotypes of A, B, and C respectively?
