Solution:

In pea plant, Green pod (G) is dominant over yellow pod (g) and Round seed (R) is dominant over wrinkled seed (r). Genotype of a pure pea plant with yellow pod and round seeds: ggRR. It will produce gametes with gR. Genotype of a pure pea plant with green pods and wrinkled seeds: GGrr. It will produce gametes with Gr. Thus their F1 offspring will have GgRr genotype which is a pea plant with green pod and round seeds
