You are given a pea that produces round, yellow seeds (both dominant traits, alleles R and Y), but its genotype is unknown. You cross this pea with a true-breeding recessive (for both traits, alleles r and y) individual to determine the genotype at both loci, and find that the offspring have the following ratios of phenotypes: ½ round, yellow, ½ round, green. What is the genotype of the unknown plant? O RrYY ORRYY ORRYY RrYy
