The genotype and phenotype ratio for the first cross will be 100% Rr and 100% round, while the second cross will be 1RR:1Rr, 50/50 round and wrinkled respectively.

Monohybrid crosses

Assuming that the seed shape allele is R(r).

For the first cross:             RR    x    rr

                                        Rr   Rr   Rr   Rr

Genotype ratio = 100% Rr

Phenotype ratio = 100% round

For the second cross:           RR    x    Rr

                                             RR   Rr   RR   Rr

Genotype ratio = 1RR : 1Rr

Phenotype ratio = 50% round and 20% wrinkled.
