Description
Summary:Background: The extent to which selection determines interspecific patterns of genetic exchanges enlightens the role of adaptation in evolution and speciation. Often reported extensive interspecific introgression could be selection-driven, but also result from demographic processes, especially in cases of invasive species replacements, which can promote introgression at their front. Because invasion and selective sweeps similarly mold variation, population genetics evidence for selection can only be gathered in an explicit demographic framework. The Iberian hare, Lepus granatensis, displays in its northern range extensive mitochondrial DNA introgression from L. timidus, an arctic/boreal species that it replaced locally after the last glacial maximum. We use whole-genome sequencing to infer geographic and genomic patterns of nuclear introgression and fit a neutral model of species replacement with hybridization, allowing us to evaluate how selection influenced introgression genome-wide, including for mtDNA. ... : Hare (Lepus) pseudo-reference genome built through iterative mapping of sequencing reads from Lepus timidus, Lepus granatensis and Lepus americanus on the European rabbit (Oryctolagus cuniculus) genome template (available from ftp://ftp.ensembl.org/pub/release-80/fasta/oryctolagus_cuniculus/dna/). ...
