When pea plant with round shaped seeds with yellow colour seed (RRYY) is crossed with pea plant showing wrinkled shape with green cotyledons (rryy), the F1 generation will have round shaped seeds with yellow colour seed (RrYy) progeny. When this plants are crossed, the F2 generation will have progeny in the ratio of 9:3:3:1 as genotype and 3:1 as the phenotype.
