<i>D. melanogaster</i> and <i>D. simulans Lhr</i> orthologs suppress hybrid rescue by <i>D. simulans Lhr</i>.<i>¹</i>

<p>Crosses were between <i>D. melanogaster</i> females heterozygous for the different transgenes tested (<i>w; φ{transgene, w⁺}</i>) and <i>D. simulans Lhr¹</i> males. Transgenes are denoted as <i>φ{}</i> in the table. The transgenes carry a copy of the <i>w⁺</i> gene so the hybrid sons inheriting the transgene (genotype 2) were distinguished from their control siblings (genotype 1) by their eye-colour, except for cross 8 where <i>D. melanogaster</i> females homozygous for the integration site without an inserted transgene were mated to <i>D. simulans Lhr¹</i> males. NA = not applicable. RT = room temperature.
