UAS regulatory sequences drive expression of Lhr which is tagged at the C-terminal end with Venus.
Expression of LhrC.Scer\UAS.T:Avic\GFP-YFP.Venus under the control of Scer\GAL4Act5C.PI in the hybrid male progeny of a cross between D.melanogaster females and D.simulans males suppresses the male hybrid rescue conferred by Dsim\Lhr1.
