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. If 500 F2 offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers

94.            

Explanation:

If 500 F2 offspring resulted from the cross, approximately 94 plants out of 500 plants have red, terminal flowers. The offspring produced in F2 generation in the ratio of 9:3:3:1. According to this ratio, 281 plants having red axial flowers, 94 plants have red terminal flowers, 94 plants have white axial flowers and 31 plants having white terminal flowers. So by totaling 500 plants are received.
