Use the following information to answer the question below.

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.


If 1000 F2 offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers?

Answer:

750

Explanation:

With the f1 generation all being red flowers we can conclude that Red is dominant (R) and white is recessive (r).

This leads to the f1 generation having Rr. If you breed two Rr together you get

1 RR

2 Rr

1 rr

75% of the f2 will have red flowers. So if you take 1000 and multiply it by .75 you will get 750

Approximately 750 flowers will be Red.
