Inferring population demographic history with admixture under the so-called admixture network model from population genetic data is an established problem in genetics. Existing admixture network inference approaches work with single genetic polymorphisms. While these methods are usually very fast, they do not fully utilize the information [e.g. linkage disequilibrium (LD)] contained in population genetic data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In this article, we develop a new admixture network inference method called GTmix. Different from existing methods, GTmix works with local gene genealogies that can be inferred from population haplotypes. Local gene genealogies represent the evolutionary history of sampled haplotypes and contain the LD information. GTmix performs coalescent-based maximum likelihood inference of admixture networks with inferred local genealogies based on the well-known multispecies coalescent (MSC) model. GTmix utilizes various techniques to speed up the likelihood computation on the MSC model and the optimal network search. Our simulations show that GTmix can infer more accurate admixture networks with much smaller data than existing methods, even when these existing methods are given much larger data. GTmix is reasonably efficient and can analyze population genetic datasets of current interests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Availability and implementation<\/jats:title>\n                    <jats:p>The program GTmix is available for download at: https:\/\/github.com\/yufengwudcs\/GTmix.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Supplementary information<\/jats:title>\n                    <jats:p>Supplementary data are available at Bioinformatics online.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/bioinformatics\/btaa465","type":"journal-article","created":{"date-parts":[[2020,5,4]],"date-time":"2020-05-04T08:13:01Z","timestamp":1588579981000},"page":"i326-i334","source":"Crossref","is-referenced-by-count":8,"title":["Inference of population admixture network from local gene genealogies: a coalescent-based maximum likelihood approach"],"prefix":"10.1093","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4988-3521","authenticated-orcid":false,"given":"Yufeng","family":"Wu","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, University of Connecticut , Storrs, CT 06269, USA"}]}],"member":"286","published-online":{"date-parts":[[2020,7,13]]},"reference":[{"key":"2024021913334921800_btaa465-B1","doi-asserted-by":"crossref","first-page":"1084","DOI":"10.1086\/521987","article-title":"Rapid and accurate haplotype phasing and missing data inference for whole genome association studies by use of localized haplotype clustering","volume":"81","author":"Browning","year":"2007","journal-title":"Am.
