In rabbits, white fur (W) is dominant to black (w), and long ears (E) are dominant to short ears (e). A breeder mates two rabbits that are heterozygous (WwEe) for both traits. What is the chance that the offspring will be black with long ears?

In pea plants tall (T) is dominant to short, and axial (A) is dominant to terminal. A tall pea plant with terminal flowers (flowers on the end of the stems) is crossed with a short pea plant that has axial flowers (flowers in the middle of the stems). All 72 offspring are tall with axial flowers. What are the genoytpes of the parents in the cross?
