Fig. S2.

Eye antennal discs and adult phenotypes from Pax6 knockdown animals. (A and B) Third-instar larval eye-antennal discs from DE-GAL4 > toy RNAi and DE-GAL4 > ey RNAi larvae at 25 °C. The orange and yellow arrows mark the dorsal half of the disc where DE-GAL4 is expressed and Toy/Ey proteins are absent. Adult heads from (C and D) DE-GAL4 > toy RNAi, (E) DE-GAL4 > ey RNAi, (F) DE-GAL4 > toy RNAi; ey², and (G) DE-GAL4 > ey RNAi; toy¹. Red arrow marks the loss of one half of the head and orange arrow marks the fusion of two ocelli in the DE > toyRNAi flies. (Scale bars, 100 µm.)
