Approximately 8.6kb NotI/XbaI genomic fragment that extends from approximately 2.8kb 5' of Dsim\Hmr to approximately 1.05kb 3' of Dsim\Hmr. This fragment also contains the complete predicted coding region of Dsim\CG2124.
Hmr2 suppresses hybrid male lethality of hybrid sons of crosses between D.melanogaster females and D.simulans males. This hybrid rescue is not suppressed if the hybrids also carry Dsim\Hmr+t8.6 or Dmau\Hmr+t9.4.
Hmr1 suppresses hybrid male lethality of hybrid sons of crosses between D.melanogaster females and D.mauritiana males. This hybrid rescue is not suppressed if the hybrids also carry Dsim\Hmr+t8.6 or Dmau\Hmr+t9.4.
The sterility of hybrid daughters of crosses between D.melanogaster females and D.simulans males is suppressed by Hmr2. This Hmr2-dependent rescue of hybrid female sterility is not affected if the hybrids also carry Dsim\Hmr+t8.6.
In(1)AB suppresses hybrid male lethality of hybrid sons of crosses between D.melanogaster females and D.simulans males. This hybrid rescue is not suppressed if the hybrids also carry Dsim\Hmr+t8.6 or Dmau\Hmr+t9.4. Hmr1 suppresses hybrid male lethality of hybrid sons of crosses between D.melanogaster females and D.mauritiana males. This hybrid rescue is not suppressed if the hybrids also carry Dsim\Hmr+t8.6 or Dmau\Hmr+t9.4. The sterility of hybrid daughters of crosses between D.melanogaster females and D.simulans males is suppressed by In(1)AB. This In(1)AB-dependent rescue of hybrid female sterility is not affected if the hybrids also carry Dsim\Hmr+t8.6.
The reduced viability of HmrDf/HmrDf females that is seen at 27[o]C is not rescued by Dsim\Hmr+t8.6, while the reduced fertility phenotype of HmrDf/HmrDf females is partially complemented by Dsim\Hmr+t8.6.
Assayed in D.melanogaster/D.simulans and D.melanogaster/D.mauritiana hybrids.
