We\u00a0have developed a method---called Graph-aware Retrieval of Selective Sweeps (GRoSS)---for detecting signatures of strong positive\u00a0selection on the branches of complex admixture graphs among a\u00a0set of populations. Here, we apply the method to whole-genome sequence variation of Atlantic cod population from throughout its distributional\u00a0range. We detect several regions of strong selection and\u00a0putative candidate genes. We also detect large regions of differentiation\u00a0due to inversions, associated with behavioral ecotypes, and we are able to pinpoint in which populations or on which\u00a0branches in the history of Atlantic cod the variants originated\u00a0or have been under the strongest selection. Structural chromosomal variation is important in local adaptation and speciation.<\/p>","protected":false},"excerpt":{"rendered":"<p>Einar \u00c1rnason, Katr\u00edn Halld\u00f3rsd\u00f3ttir, Alba Refoyo-Mart\u00ednez, Thomas Mailund, and Fernando Racimo. 2019.\u00a0Detecting signatures of strong positive selection on\u00a0branches of an admixture graph of Atlantic cod populations.
