tsrhs.PB; tsrΔ96 flies show extensive planar cell polarity defects. In adult wings, the hairs do not uniformly point distally as they do in wild type. In the eye, ommatidia show random chirality and polarity. In the abdomen, fine hairs and bristles frequently have non-posterior orientations. Legs display aberrant tarsal joints and joint duplications and leg bristles often show non-distal orientations. Bracts at the base of bristle show opposite directions; for example, two bracts may have correct polarity but the third may have reversed polarity.
