Migration restores hybrid incompatibility driven by mitochondrial-nuclear sexual conflict.

Abstract excerpt

In the mitochondrial genome, sexual asymmetry in transmission allows the accumulation of male-harming mutations since selection acts only on the effect of the mutation in females. Called the 'Mother's Curse', this phenomenon induces a selective pressure for nuclear variants that compensate for this reduction in male fitness. Previous work has demonstrated the existence of these interactions and their potential to...
