In a cross between homozygous wild-type drosophila and yellow-bodied males of all of the f1's were phenotypically wild-type. the f2 generation (resulting from matings of the f1's) had 356 wild-type offspring. however, all 240 females were wild-type and of the 239 males, 116 were wild-type and 123 were yellow-bodied. how is the yellow-bodied trait inherited?
