Figure 6

Double Oc-Ubx + Oc-abd-A(RNAi) phenotype. Larva that had both Oc-Ubx and Oc-abd-A knocked down by parental RNAi has legs on A1 (white arrowheads) and A4 (black arrowheads) as in the single-gene RNAi. The A3 appendages (yellow arrows) also resemble legs, but are missing terminal parts. This A3 'leg’ is enlarged in the inset; the asterisk marks the distal tip lacking the claw. A1, A3 and A4 mark the first, the third and the fourth abdominal segments, respectively. Scale bar: 200 μm.
