Figure 9.30

Antibody staining of the Ultrabithorax protein in (A) the wing disc and (B) the haltere disc of third instar Drosophila larvae. These are the cells that will give rise to a wing and a haltere, respectively. In the wing disc, Ultrabithorax staining can be seen only on the cells that form the peripodial membrane, and not on those that form the wing itself. In the haltere disc, the Ultrabithorax protein is found in those cells that will produce the major portion of the haltere. (From Weatherbee et al. 1998; photographs courtesy of S. D.
