Antennapedia (Ant) homeotic mutant in Drosophila

    Homeotic mutations affect normal development of the imaginal disks that produce cuticular structures (antennae, wings, halteres, legs, etc.). The Ant mutant results in transdetermination of disks that ordinarily produce antennae (left) in the standard phenotype into disks that produce leg structures (right). The mutant phenotype has legs growing out of the head.
