Drosophila melanogaster body color is controlled by one gene while wing shape is controlled by a second gene.  Gray body color is dominant to black body color, and normal wings are dominant to vestigial wings.  Flies homozygous for gray body color and vestiial wing are crossed with flies homozygous for black body color and normal wings
