sex comb | ectopic, with Scer\GAL4Tub.PU, sxc3
Expression of P{Sym-UAS-sxc} under the control of Scer\GAL4tub reduces viability in a P{Sym-UAS-sxc}-insert dependent manner. For the P{Sym-UAS-sxc}1m, P{Sym-UAS-sxc}2m, P{Sym-UAS-sxc}5m and P{Sym-UAS-sxc}8m insertions, this lethality is dramatically enhanced in a sxc3/+ background, with dead male pharate adults exhibiting ectopic sex combs in the case of P{Sym-UAS-sxc}1m and P{Sym-UAS-sxc}2m.
