Flies homozygous for ry mutations exhibit a rosy eye color. ry41 and ry564 are two different alleles of ry. ly (lyra wings ) and sb (stubble bristles) are dominant alleles of two genes to the left and right of the ry locus respectively. heterozygous females with ry41 sb on one chromosome and ly ry564 on the other chromosome are mated to ry41 males. out of a large number of progeny, a few flies are recovered that have wild type eyes, lyra wings and stubble bristles. a) what is the most logical explanation for this result
