Expression of cortoCD.Scer\UAS.T:Zzzz\FLAG,T:Ivir\HA1,T:Uuuu\nls6 under the control of either Scer\GAL4Act5C.PU or Scer\GAL4da.G32 induces high lethality. Male escapers expressing cortoCD.Scer\UAS.T:Zzzz\FLAG,T:Ivir\HA1,T:Uuuu\nls6 under the control of Scer\GAL4da.G32 display rotated genitalia and sex combs and duplicated macrochaetae. Very penetrant homeotic phenotypes are also seen, with aristae partially transformed into leg. The sex combs are small compared to controls.
