The Dobzhansky-Muller model is agnostic with respect to why causal genes diverge, but evidence from several studies in Drosophila suggests that hybrid incompatibility may arise as a by-product of adaptive evolution, since the few known incompatibility genes are all rapidly evolving [5–7]. However, despite ...
WebAug 23, 2024 · These weak Dobzhansky-Muller incompatibilities confer partial hybrid inviability with sex biases in crosses between European and East Asian domestic pigs.
