{"abstract":[{"text":"We investigate the probability of fixation of a chromosome rearrangement in a subdivided population, concentrating on the limit where migration is so large relative to selection (m ≫ s) that the population can be thought of as being continuously distributed. We study two demes, and one- and two-dimensional populations. For two demes, the probability of fixation in the limit of high migration approximates that of a population with twice the size of a single deme: migration therefore greatly reduces the fixation probability. However, this behavior does not extend to a large array of demes. Then, the fixation probability depends primarily on neighborhood size (Nb), and may be appreciable even with strong selection and free gene flow (≈exp(-B·Nb) in one dimension, ≈exp(-B\\cdotNb) in two dimensions). Our results are close to those for the more tractable case of a polygenic character under disruptive selection.","lang":"eng"}],"publisher":"Wiley-Blackwell","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","external_id":{"pmid":["28568824"]},"page":"499 - 517","oa_version":"None","pmid":1,"publication":"Evolution","doi":"10.1111/j.1558-5646.1991.tb04326.x","date_updated":"2022-03-02T10:37:19Z","day":"01","extern":"1","language":[{"iso":"eng"}],"year":"1991","main_file_link":[{"url":"http://www.jstor.org/stable/2409908"}],"publist_id":"2735","article_type":"original","publication_identifier":{"issn":["0014-3820"],"eissn":["1558-5646"]},"intvolume":"        45","month":"05","author":[{"full_name":"Barton, Nicholas H","orcid":"0000-0002-8548-5240","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","last_name":"Barton","first_name":"Nicholas H"},{"first_name":"Shahin","last_name":"Rouhani","full_name":"Rouhani, Shahin"}],"citation":{"short":"N.H.
