 Ectopic expression of Dll in the wing disc activates the endogenous gene and represses the wing-specific gene vg. (A) Dll–lacZ expression pattern. (B) Vg wild-type expression pattern. (C) Merged channels. (D) Dll–lacZ expression pattern of omb–GAL4/UAS–Dll wing discs. (E) Vg expression pattern in the same disc. (F) Merge channels. Arrows indicate the repression of Vg and the activation of endogenous Dll. Here and in all remaining images of wing discs, ventral is at the top and anterior is to the left.
