7. A male fly that is homozygous for recessive alleles at two linked autosomal genes is mated with a wild-type female fly that is homozygous dominant for both alleles. All F, offspring are then randomly mated. If the genes are so close as to have no recombination, what proportion of offspring will be homozygous for both mutations in the F, generation? Briefly justify your answer.
