| Popis: | A recent study demonstrated that British red foxes introduced to the mid-Atlantic coastal plain (ACP) of the eastern United States during the late 18th century successfully interbred with indigenous American red foxes despite half a million year’s divergence. However, a large disparity in frequency of European mitochondria (27%) versus Y chromosomes (1%) left unclear the magnitude of genetic exchange. We sought to quantify genomic introgression using 35 autosomal and 5 X-chromosome ancestry-informative markers (AIMs) in conjunction with diagnostic Y chromosome single nucleotide polymorphism (Y-SNP) markers to characterize the modern state of red foxes in the eastern United States and to gain insight into the potential role of reproductive barriers. European admixture was highest in the ACP and apparently restricted to the central eastern United States. We estimated only slightly (and nonsignificantly) European ancestry in autosomal than X-chromosome markers. European ancestry from autosomal and X-chromosome markers (36.4%) was higher than the corresponding mitochondrial (mt) DNA estimate (26.4%) in the ACP. Only 1 of 124 males ( |
