Flower color in petunia is determined by the alleles of single gene. Purple flowers are fully dominant to white flowers. Suppose a plant homozygous for purple flowers is crossed with a plant that has white flowers. Determine the phenotypes and frequencies of the following: a. The phenotypes and frequencies of the F1 flowers. b. The phenotypes and frequencies of the F2 flowers. c. The phenotypes and frequencies of the offspring of a cross of the F1 petunias back to the purple parent. d. The phenotypes and frequencies of the offspring of a cross of the F1 petunias back to the white parent. e. The phenotypes and frequencies (all together) of the offspring of crossing the purple F2 petunias back to the purple parent. f. The phenotypes and frequencies (all together) of the offspring of crossing the purple F2 petunias back to the white parent.
