In a plant species, you notice that purple and yellow leaf colors segregate. Interestingly, hairy and smooth stems segregate, as well. You cross a true-breeding plant with purple leaves and hairy stems to a true-breeding plant with yellow leaves and smooth stems. You testcross the F1 from this cross to generate the following testcross progeny. Phenotypes yellow leaves, hairy stems purple leaves, hairy stems purple leaves, smooth stems yellow leaves, smooth stems Numbers 68 66 22 25 Total: 181 a) Indicate the most likely genotypes of each parent. b) What pattern of inheritance could explain the progeny results? Based on your answer, what ratios would be expected for the four classes of progeny? c) Using the chi-square method, test your ratios and indicate whether you accept them or reject them.
