Models of recurrent selective sweeps traditionally assume that in chromosomal regions of normal recombination rates at most one beneficial allele is on the way to fixation. We review and extend here the theoretical studies on interference between closely linked beneficial mutations suggesting that this assumption may be violated. We show that interference between beneficial mutations may lead to substantially increased fixation times even in chromosomal regions of normal recombination rates. Furthermore, we discuss how interference can be detected in population genomic studies by analyzing genetic footprints of selective sweeps, and search for empirical evidence of interference in published datasets.<\/jats:p>","DOI":"10.3390\/biology15171561","type":"journal-article","created":{"date-parts":[[2026,9,7]],"date-time":"2026-09-07T08:07:06Z","timestamp":1788768426000},"page":"1561","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Interference of Competing Beneficial Mutations on Recombining Chromosomes"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9437-5916","authenticated-orcid":false,"given":"Wolfgang","family":"Stephan","sequence":"first","affiliation":[{"name":"Faculty of Biology, Ludwig-Maximilian University of Munich, D-82152 Planegg-Martinsried, Germany"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]},{"given":"Stefan","family":"Laurent","sequence":"additional","affiliation":[{"name":"Department of Comparative Development and Genetics, Max Planck Institute for Plant Breeding Research, D-50829 Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"},{"role":"software","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"879","DOI":"10.1093\/genetics\/147.2.879","article-title":"The evolution of recombination: Removing the limits to natural selection","volume":"147","author":"Otto","year":"1997","journal-title":"Genetics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1214\/EJP.v17-1954","article-title":"Fixation probability for competing selective sweeps","volume":"17","author":"Cuthbertson","year":"2012","journal-title":"Electron.
