Breeding designs that maintain a large effective population size with randomized assignment of breeders at each generation can minimize the impact of selection, inbreeding, and genetic drift on allele frequencies. Small deviations from expected allele frequencies will have little effect on the power and precision of genetic analysis, but a major distortion could result in reduced power and loss of important functional alleles. We detected strong transmission ratio distortion in the Diversity Outbred (DO) mouse population on chromosome 2, caused by meiotic drive favoring transmission of the WSB\/EiJ allele at the R2d2 locus. The distorted region harbors thousands of polymorphisms derived from the seven non-WSB founder strains and many of these would be lost if the sweep was allowed to continue. To ensure the utility of the DO population to study genetic variation on chromosome 2, we performed an artificial selection against WSB\/EiJ alleles at the R2d2 locus. Here, we report that we have purged the WSB\/EiJ allele from the drive locus while preserving WSB\/EiJ alleles in the flanking regions. We observed minimal disruption to allele frequencies across the rest of the autosomal genome. However, there was a shift in haplotype frequencies of the mitochondrial genome and an increase in the rate of an unusual sex chromosome aneuploidy. The DO population has been restored to genome-wide utility for genetic analysis, but our experience underscores that vigilant monitoring of similar genetic resource populations is needed to ensure their long-term utility.<\/jats:p>","DOI":"10.1534\/g3.116.035527","type":"journal-article","created":{"date-parts":[[2016,10,7]],"date-time":"2016-10-07T21:14:26Z","timestamp":1475874866000},"page":"3893-3902","source":"Crossref","is-referenced-by-count":77,"title":["Diversity Outbred Mice at 21: Maintaining Allelic Variation in the Face of Selection"],"prefix":"10.1093","volume":"6","author":[{"given":"Elissa J","family":"Chesler","sequence":"first","affiliation":[{"name":"The Jackson Laboratory, Bar Harbor, Maine 04609"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel M","family":"Gatti","sequence":"additional","affiliation":[{"name":"The Jackson Laboratory, Bar Harbor, Maine 04609"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew P","family":"Morgan","sequence":"additional","affiliation":[{"name":"Department of Genetics, Lineberger Comprehensive Cancer Center, University of North Carolina at Chapel Hill, North Carolina 27599-7264"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marge","family":"Strobel","sequence":"additional","affiliation":[{"name":"The Jackson Laboratory, Bar Harbor, Maine 04609"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Trepanier","sequence":"additional","affiliation":[{"name":"The Jackson Laboratory, Bar Harbor, Maine 04609"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denesa","family":"Oberbeck","sequence":"additional","affiliation":[{"name":"Department of Behavioral Neuroscience and Portland Alcohol Research Center, Oregon Health & Science University, Oregon 97201"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shannon","family":"McWeeney","sequence":"additional","affiliation":[{"name":"Department of Behavioral Neuroscience and Portland Alcohol Research Center, Oregon Health & Science University, Oregon 97201"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Hitzemann","sequence":"additional","affiliation":[{"name":"Department of Behavioral Neuroscience and Portland Alcohol Research Center, Oregon Health & Science University, Oregon 97201"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Ferris","sequence":"additional","affiliation":[{"name":"Department of Genetics, Lineberger Comprehensive Cancer Center, University of North Carolina at Chapel Hill, North Carolina 27599-7264"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rachel","family":"McMullan","sequence":"additional","affiliation":[{"name":"Department of Genetics, Lineberger Comprehensive Cancer Center, University of North Carolina at Chapel Hill, North Carolina 27599-7264"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amelia","family":"Clayshultle","sequence":"additional","affiliation":[{"name":"Department of Genetics, Lineberger Comprehensive Cancer Center, University of North Carolina at Chapel Hill, North Carolina 27599-7264"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timothy A","family":"Bell","sequence":"additional","affiliation":[{"name":"Department of Genetics, Lineberger Comprehensive Cancer Center, University of North Carolina at Chapel Hill, North Carolina 27599-7264"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando Pardo-Manuel","family":"de Villena","sequence":"additional","affiliation":[{"name":"Department of Genetics, Lineberger Comprehensive Cancer Center, University of North Carolina at Chapel Hill, North Carolina 27599-7264"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gary A","family":"Churchill","sequence":"additional","affiliation":[{"name":"The Jackson Laboratory, Bar Harbor, Maine 04609"},{"name":"The Jackson Laboratory, Bar Harbor, Maine 04609"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2016,12,1]]},"reference":[{"key":"2021101614424813300_bib1","doi-asserted-by":"crossref","first-page":"1213","DOI":"10.1101\/gr.111310.110","article-title":"Genetic analysis of complex traits in the emerging Collaborative Cross.","volume":"21","author":"Aylor","year":"2011","journal-title":"Genome Res."},{"key":"2021101614424813300_bib2","doi-asserted-by":"crossref","first-page":"382","DOI":"10.1007\/s00335-008-9135-8","article-title":"The Collaborative Cross at Oak Ridge National Laboratory: developing a powerful resource for systems genetics.","volume":"19","author":"Chesler","year":"2008","journal-title":"Mamm.
