Mendel crossed a pea plant that produced plump and rounded seeds with a pea plant that produced wrinkled seeds. In the F 1 generation, all seeds were round. Mendel planted the F 1 seeds, which grew into plants that, when self-fertilized, produced 5,474 round seeds and 1,850 wrinkled seeds in the F 2 generation. The alleles that govern seed shape are designated R and r.
a. What are the genotypes of the parents
b. What are the possible outcomes of a cross between a homozygous round-seeded plant and a wrinkle-seeded plant
