- A plant of genotype Aa; Bb; Cc is fertilized by a plant that is completely dominant for each of the genes. (Assume that A, B, and C are dominant to a, b, c and that the three genes assort independently). What proportion of the offspring will have the same phenotype as the heteroallelic plant? Use the branch-line method to answer this question.
