--- res: bibo_abstract: - In large populations, multiple beneficial mutations may be simultaneously spreading. In asexual populations, these mutations must either arise on the same background or compete against each other. In sexual populations, recombination can bring together beneficial alleles from different backgrounds, but tightly linked alleles may still greatly interfere with each other. We show for well-mixed populations that when this interference is strong, the genome can be seen as consisting of many effectively asexual stretches linked together. The rate at which beneficial alleles fix is thus roughly proportional to the rate of recombination and depends only logarithmically on the mutation supply and the strength of selection. Our scaling arguments also allow us to predict, with reasonable accuracy, the fitness distribution of fixed mutations when the mutational effect sizes are broad. We focus on the regime in which crossovers occur more frequently than beneficial mutations, as is likely to be the case for many natural populations.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Daniel foaf_name: Weissman, Daniel foaf_surname: Weissman foaf_workInfoHomepage: http://www.librecat.org/personId=2D0CE020-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Oskar foaf_name: Hallatschek, Oskar foaf_surname: Hallatschek bibo_doi: 10.1534/genetics.113.160705 bibo_issue: '4' bibo_volume: 196 dct_date: 2014^xs_gYear dct_language: eng dct_publisher: Genetics Society of America@ dct_title: The rate of adaptation in large sexual populations with linear chromosomes@ ...
