Two true-breeding stocks of pea plants are crossed. One parents 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.
a) If 1,000 F2 offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers?
b) Among the F2 offspring, what is the probability of plants with white axial flowers?
