was selfed to obtain F2 progeny. Answer the following questions:
a. State the color of flower and genotype you would expect in their F1 progeny.
b. What must be the percentage of purple flowers and white flowers in the F2 generation.
c. What is this cross called? State the expected genotypic ratio of BB and bb in F2
generation? Which one is the dominant trait and which one is the recessive trait?
