Fig. 5. Clones involving Vang. (A) Vang^– clone in anterior tergites marked with pawn. Note that the rows of hairs in the clones are disordered and the orientation is disturbed (genotype 28). Anterior to the clone, there is some reversal of hair polarity (yellow arrowheads). (B) This clone carries only the pawn marker and can be compared with A (genotype 30). Note that the rows of hairs are well ordered and the polarity normal (blue arrowheads). (C) Vang^– clone (marked with pawn) in the pleura. Hairs in the clone are dishevelled, but the hairs in front are reversed in polarity (genotype 28). (D) A clone expressing Vang (marked with pawn) showing slight disarray inside the clone, and the reversal of polarity of the hairs behind (yellow arrowheads, genotype 31). (E) A clone expressing Vang (marked with multiple wing hairs, in which every cell has multiple hairs that point in all directions), in a Vang^– fly. Note that the background hairs are higgledy-piggledy in orientation, but, unlike in D, they are not affected by the clone (genotype 32). (F) A clone expressing Vang (marked with pawn), in a fz^– fly. Note that the hairs in front of the clone are dishevelled because fz^– affects that region of the A compartment, but behind they are normal, and, unlike in Fig. 5D, they are unaltered by the clone (blue arrowheads, genotype 36).
