2) A different "green-round" individual of the same pea species was crossed with a plant grown from a white, wrinkled pea. The following offspring were obtained: 37 green round, 44 green wrinkled, 41 white round and 35 white wrinkled. a) what were the parental genotypes this time? b) explain the ratio by means of a diagram. c) What other genotypes could the green round parent have had? Predict the offspring that would have resulted

The following offspring were obtained: 37 green round, 44 green wrinkled, 41 white round and 35 white wrinkled. a) what were the parental genotypes this time? b) explain the ratio by means of a diagram. c) What other genotypes could the green round parent have had? Predict the offspring that would have resulted in each case. d) Crossing an individual with an unknown genotype with an individual showing the recessive phenotype(s) is know as a test cross. What is the advantage of using the individual with the recessive phenotype(s)?
