Fig. 6. pygo is epistatic to Axin. (A-C) Confocal images of wing imaginal discs stained for Sens. Clones (indicated by the white lines) of pygo¹⁰ (A), Axin (B) and Axin, pygo¹⁰ (C) indicate that the double mutant phenotype (loss of Sens in the clone) is identical to pygo. (D-F) Confocal images of eye-antennal imaginal discs stained for the photoreceptor marker Elav (red) and clonal marker lacZ (green). Clones (indicated by lack of ß-gal staining) of pygo¹⁰ (D), Axin (E) and Axin, pygo¹⁰ (F) indicate that the double mutant phenotype (unaffected photoreceptor clusters in the clones) is identical to pygo.
