Chromosomal inversions are frequently implicated in isolating species. Models have shown how can evolve the context of postmating isolation. Inversions also associated with mating preferences, a topic that has not been studied theoretically. Here, we show spread by capturing preference locus and one or more loci involved epistatic incompatibilities. be established under broad conditions ranging from near panmixis to nearly complete speciation. These results provide hypothesis explain growing number examples premating mechanisms.
