Genomic tracts in Mus musculus samples that were inferred to originate via introgression with M. spretus. PhyloNet-HMM [11] was used to infer genomic signatures of interspecific introgression using the procedure described by Liu et al. [5]. Only western European and north African samples are shown. Samples are labeled by country, city/region (if multiple samples originated from the same country), and identifier (if multiple samples originated from the same city/region). The haploid chromosomes are shown for each sample in a separate track and colored a non-white color to denote introgressive origin or white otherwise; each sample is assigned a different color for visibility. The chart shows a subset of the introgressed genomic regions that were inferred to originate due to the recent selective sweep associated with anticoagulant pesticide use. The location of the Vkorc1 gene is highlighted, which is known to contribute to anticoagulant resistance in both mice and humans [4], [12]. Panel adapted from [5]
