Fig. 7. Ventral cuticles of third instar larvae. The denticle bands from the first and second abdominal segments are shown, with a wild-type larva on the left and a Uab^HH1 homozygous larva on the right. The segmental transformations are subtle. In the mutant, the A1 denticle band has slightly more and larger denticles than wild type, while the A2 denticle band has slightly fewer denticles.
