7) In a plant species, flowers may be yellow, blue, red, or mauve. Two crosses involving true breeding parents were conducted with the following results:
Blue-flowered plant X red-flowered plant ? all F1 plants have yellow flowers. F2 generation: 9/16 yellow, 3/16 blue, 3/16 red and 1/16 mauve.
yellow-flowered plant X mauve-flowered plant ? all F1 plants have yellow flowers. F2 generation: 9/16 yellow, 3/16 blue, 3/16 red and 1/16 mauve.
(a) How many different genes are involved in the inheritance of flower color in this species?
(b) Describe the inheritance of flower color in this plant species by providing genotypes for all individuals in the parental, F1, and F2 generations of both crosses indicated above.
(c) Determine the F1 and F2 results of a cross between a true-breeding red and a true-breeding mauve plant.
