In а series оf crоsses invоlving peа plаnts that have round seeds and yellow cotyledons with pea plants that have wrinkled seeds and green cotyledons, the following ratios were observed in progeny. On the basis of these ratios, determine the genotypes of parental plants for each cross. Parent Phenotype Progeny Cross 1: Round, yellow x round yellow 9/16 round, yellow 3/16 round, green 3/16 wrinkled, yellow 1/16 wrinkled, green Cross 2: Round, yellow x round, yellow 3/4 round, yellow 1/4 wrinkled, yellow Cross 3: Wrinkled, yellow x round, yellow 6/16 wrinkled, yellow 2/16 wrinkled, green 6/16 round, yellow 2/16 round, green What genotypes are possible for the parents in cross 2?
