Insertion of approximately 4kb in the predicted 5' untranslated region, resulting in reduced transcription compared to controls. The insertion appears to be moderately repetitive retrotransposed sequence.
When Drosophila simulans carries Dsim\Lhr1, classes of hybrids between D.simulans and D.melanogaster that do not ordinarily survive are recovered. Crosses of D.melanogaster females by D.simulans males, which ordinarily produce only daughters, produce sons and daughters in a 1:1 ratio. Crosses of D.simulans females to D.melanogaster males, which ordinarily produce only sons, produce 86% sons and 14% daughters. Crosses of C(1)RM - bearing D.melanogaster females to D.simulans males, which normally produce only sons, yield a few daughters when the D.simulans males carry Dsim\Lhr1.
Hybrid male progeny of a cross of D. melanogaster females to D. simulans Dsim\Lhr1 males have a viability of approximately 73% relative to their hybrid female siblings.
Lhr+t4.8 fully complements Dsim\Lhr1, which is observed as hybrid male inviability in the progeny of a cross of D. melanogaster females carrying Lhr+t4.8 to D. simulans Dsim\Lhr1 males.
LhrT:Ivir\HA1 fully complements Dsim\Lhr1, which is observed as hybrid male inviability in the progeny of a cross of D. melanogaster females carrying LhrT:Ivir\HA1 to D. simulans Dsim\Lhr1 males.
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.
Expression of Dsim\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.
Expression of Dvir\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 does not significantly suppress the male hybrid rescue conferred by Dsim\Lhr1.
Expression of Dyak\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.
