In sweet peas, purple flower color (P) is dominant over white (p), but there is also a control gene such that if the plant has a “C”, the purple has “permission” to express itself. If the plant is “cc,” the purple does not “have permission” to express itself and the flower will be white anyway. If a plant with homozygous purple, controlled flowers is crossed with a plant with white, non-controlled flowers, calculate the genotype and phenotype ratios of the F1 and F2 generations.

In a species of plants, axial flowers are dominant to terminal flowers and the trait for height is incompletely dominant. A medium height plant with axial flowers (double heterozygote) is crossed with another double heterozygote plant. What are the genotypic and phenotypic ratio of the offspring?
