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?

Speciation in ancestor as following way

A- Non-swimming populations separated by a river may gradually diverge because there is no gene flow between them
