Strong UAS-ogre expression in the developing wing margin produces a strong wing-serration phenotype.
Photograph of a wing from an animal of genotype C96GAL4 / +; UAS-ogre 3UO9/+. Strong wing serration is observed (arrowheads). The C96GAL4 line drives expression in the wing margin (Gustafson and Boulianne, 1996). UAS-ogre 3UO9 is a strongly-expressing line, almost as strong, phenotypically speaking, as two copies of UAS-ogre2UO15.
