Complex evolutionary processes maintain an ancient chromosomal inversion

P Nosil, V Soria-Carrasco… - Proceedings of the …, 2023 - National Acad Sciences
Genome re-arrangements such as chromosomal inversions are often involved in adaptation.
As such, they experience natural selection, which can erode genetic variation. Thus …

The role of mitonuclear incompatibilities in allopatric speciation

RS Burton - Cellular and Molecular Life Sciences, 2022 - Springer
