Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers; all F1 individuals have red, axial flowers. The genes for flower colour and location assort independently. Among the F2 offspring, what is the probability of producing plants with white axial flowers?

Question

Quizplus · Accepted Answer

The F1 generation shows that red and axial are dominant traits. In the F2 generation, the probability of white flowers (recessive) is 1/4 and axial flowers (dominant) is 3/4. The probability of both occurring together is 1/4 * 3/4 = 3/16.
