Two true-breeding white trains of the plant Illegitimati noncarborundum were mated, and the F_1 progeny were all white. When the F_1 plants were allowed to self-fertilize, 126 white-flowered and 33 purple-flowered F_2 plants grew. a. How could you describe inheritance of flower color? Describe how specific alleles influence each other and therefore affect phenotype. b. A white F_2 plant is allowed to self-fertilize. Of the progeny, 3/4 are white-flowered, and 1/4 are purple-flowered. What is the genotype of the white F_2 plant? c. A purple F_2 plant is allowed to self-fertilize. Of the progeny, 3/4 are purple-flowered, and 1/4 are white-flowered. What is the genotype of the purple F_2 plant? d. Two white F_2 plants are crossed with each other. Of
