UAS-ogre expression in the developing wing margin generates weak wing serration.
Photograph of a wing from an animal of genotype C96GAL4 / UAS-ogre 2UO15. Mild wing serration is observed (arrowhead). The C96GAL4 line drives expression in the wing margin ( Gustafson and Boulianne, 1996). UAS-ogre 2UO15 is a medium-strength line. Weaker UAS-ogre lines produce no phenotype and stronger ones induce more extensive serration.
