When in combination with wg^l-17 or Df(2L)RF embryos exhibit a lawn of denticles. When in combination with wg^P (In(2L)wg^P) adults show a striking ventral-to-dorsal transformation, with a sternite resembling the notum that also has microchaetae-like bristles. This phenotype cannot easily be explained in terms of transvection, the more probable interpretation is the increased severity of the phenotype reflects the absence of a distinct gene (Sternopleural) that interacts strongly with wg.
