Cytogenetic evidence is presented demonstrating that the 84A-B interval in the proximal portion of the right arm of chromosome 3 is the residence of a homoeotic gene complex similar to the bithorax locus. This complex, originally defined by the Antennapedia (A n t p) mutation, controls segmentation in the anterior portion of the organism. Different lesions within this complex homoeotically transform portions OI the prothorax, proboscis, antenna and eye and present clear analogies to similar lesions within the bithorax locus.
