On the fixation or nonfixation of inversions under epistatic selection

Brian Charlesworth, Thomas Flatt

Research output: Contribution to journalComment/debatepeer-review

Abstract

Several recent publications have stated that epistatic fitness interactions cause the fixation of inversions that suppress recombination among the loci involved. Under this type of selection, however, the suppression of recombination in an inversion heterozygote can create a form of heterozygote advantage, which prevents the inversion from becoming fixed by selection. This process has been explicitly modelled by previous workers.
