Pea plants can have various traits inherited by simple dominance. Tall is dominant to short and uses the following alleles: T = tall and t = short. Purple flower color is dominant to white flowers and uses the following alleles: P = purple and p = white. Cross the 2 plants (TtPp X ttPp) and give the probability of getting a tall white plant.
