Abstract The evolution of reproductive barriers leads to the formation new species. However, recent research has demonstrated that hybridization been pervasive across tree life even in presence strong barriers. Using swordtail fishes (genus Xiphophorus ), an emerging model system, we document overlapping mechanisms act as gene flow between birchmanni and cortezi by combining genomic sequencing from natural hybrid populations, experimental laboratory crosses, behavioural assays, sperm...
Hybridization between species is widespread across the tree of life. As a result, many species, including our own, harbor regions their genome derived from hybridization. Despite recognition that this process widespread, we understand little about how stabilizes following hybridization, and whether mechanisms driving stabilization tend to be shared species. Here, dissect drivers variation in local ancestry replicated hybridization events two pairs swordtail fish: Xiphophorus birchmanni × X ....
Natural hybridization events provide unique windows into the barriers that keep species apart as well consequences of their breakdown. Here, we characterize hybrid populations formed between northern swordtail fish Xiphophorus cortezi and birchmanni from collection sites on two rivers. We use simulations new genetic reference panels to develop sensitive accurate local ancestry calling in this novel system. Strikingly, find both rivers consist genetically distinct subpopulations: a cluster...

Here we characterize hybrid populations formed between northern swordtail fish Xiphophorus cortezi and X. birchmanni from collection sites on two rivers. We develop sensitive accurate local ancestry calling for this system based low coverage whole genome sequencing. Strikingly, find both rivers consist genetically distinct subpopulations: a cluster...
