UAS-inx7 expression in the developing wing margin generates weak wing serration.
Photograph of a wing from an animal of genotype C96GAL4 / + ; UAS-inx73U(7X)8 /+. Mild wing serration is observed (arrowhead). The C96GAL4 line drives expression in the wing margin ( Gustafson and Boulianne, 1996). UAS-inx73U(7X)8 is a strongly-expressing line encoding a wild type copy of inx7.
