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 color and location assort independently.Among the F₂ offspring,what is the probability of plants with white axial flowers?

Question

Quizplus · Accepted Answer

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