(A) Thomas Hunt Morgan conducted his experiments on $Drosophila$ $melanogaster$ to study the principles of linkage and recombination.He crossed a yellow-bodied,white-eyed male with a brown-bodied,red-eyed female.In this cross,the brown body color and red eye color are the wild-type traits (dominant),while the yellow body color and white eye color are the mutant traits (recessive).Therefore,the correct choice is $A$.
