Fig. 5. The loss of one or both systems leads to different adult and larval phenotypes. (A-D) ds^- tergites have a whorly central area but the bristle pattern is near normal (A), whereas (C) stan^- tergites are dishevelled at the front and back in the A compartment, but near normal elsewhere. (B) In ds^- stan^- tergites, both the hairs and bristles are dishevelled everywhere. (D) A normal cuticle is shown for comparison. (E-H) In the 3rd instar larvae, ds^- have disturbed hairs in the anterior rows of the ventral denticles, but the most posterior rows 5 and 6 are normal (E). The stan^- larval denticle pattern (G), as far as we can see [compare with Price et al. (Price et al., 2006)] is like wild type (H), whereas the ds^- stan^- larvae (F) show randomised polarity. Note, for A-D, adult cuticles were mounted without squashing in order to preserve bristle orientation in its native state.
