The P cross produces F1 offspring that are all heterozygous for both characteristics. The resulting 9:3:3:1 F2 phenotypic ratio is obtained using a Punnett square. In pea plants, purple flowers (P) are dominant to white (p), and yellow peas () are dominant to green (V). What are the possible genotypes and phenotypes for a cross between PPYY and ppYy pea plants?
