The humorously named sonic hedgehog gene was first discovered in this organism's embryos, in which the bicoid and hunchback genes facilitate its development from a syncytial blastoderm. The forelegs of its males have bristles, or 'sex combs'. A mutation on the smallest of its four chromosomes eliminates its ommatidia, leaving it eyeless, and Thomas Hunt Morgan studied gene linkage using its white-eyed mutant form. For 10 points, identify this model organism in which one mutation switches legs with antennae, a winged insect.
