A cross is made between two plants that are pure line genotypes DD FF G' G', and dd FF, G? G?. D is dominant to d, F is dominant to f, and G' and G? are two codominant alleles of the same gene. If the plants are crossed and the progeny are self- pollinated, and you assume all the genes are unlinked, what proportion of the F2 progeny would have the genotype dd FF G' G'? Select one: O A. 1/4 O B. 1/16 O C. 1/64 O D. 1/32 O E. 1/8
