4.8kb genomic fragment containing Lhr. The fragment extends from 2.7kb upstream to 1kb downstream of the Lhr coding sequence, and also includes the complete coding sequence of the adjacent Bap55 gene.
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.
