You are studying flower colour and shape in petunias. You have a plant with round shaped flowers that are white and cross it to a plant that has purple flowers with “frilled” petals. All of the offspring have round, purple flowers.  You locate a plant that is white and frilled and you cross it to your F1 plants. Assume both of the original parent plants were pure breeding when answering the following questions.

a)    If the genes for flower colour and shape are unlinked, what genotypes and phenotypes of offspring do you expect in the F2 and in what proportions? (2points)
