<i>D. simulans Lhr</i> interacts more strongly with <i>Hmr</i> than <i>D. melanogaster Lhr</i>.

<p>Transgenic <i>Lhr</i> orthologs were tested for interaction with two <i>Hmr</i> alleles: a null and a hypomorph, specified in the table as <i>Df(1)Hmr⁻</i> and <i>Hmr¹</i> respectively. <i>D. melanogaster</i> female parent genotypes were: null mutation, <i>y w Df(1)Hmr⁻ v/FM6</i>; <i>φ{transgene, w⁺}/+</i> and hypomorph, <i>w Hmr¹ v</i>; <i>φ{transgene, w⁺}/+</i>. Transgenes are denoted as <i>φ{}</i> in the table. Each genotype was mated separately to males from <i>D. simulans v</i> or <i>D. mauritiana Iso105</i>. Hybrid male progeny that inherit the transgene are orange eyed, while the sibling brothers are white eyed. The FET is comparing the relative viability of hybrid sons inheriting the <i>D. melanogaster Lhr</i> transgene <i>vs</i> the relative viability of sons inheriting the <i>D. simulans Lhr</i> transgene in parallel crosses.
