Figure 2.

Representative microchaetes from wild-type and mutant flies. (A–F) All micrographs were all printed at the same magnification. Notice that bristle length and width varies with the genotype of the fly. Furthermore, although all the bristles are fluted, the linearity of the fluting and their spacing is altered in the singed and singed-forked mutants. Bar, 10 μm. (G) Curvature measurements of wild-type and mutant bristles. The curvature for forked (n = 6) and singed (n = 13) microchaetes was measured from half-fly SEMs and plotted as a function of bristle length. For comparison, wild-type curvature measurements are shown in Figure 1C. Bars indicate the SE of the mean.
