| Summary: | Hybridization has played an important role in the evolutionary history of Canis species in eastern North America. Genetic evidence of coyote–dog hybridization based on mitochondrial DNA (mtDNA) is lacking compared to that based on autosomal markers. This discordance suggests dog introgression into coyotes has potentially been male biased, but this hypothesis has not been formally tested. Therefore, we investigated biparentally, maternally, and paternally inherited genetic markers in a sample of coyotes and dogs from southeastern Ontario to assess potential asymmetric dog introgression into coyotes. Analysis of autosomal microsatellite genotypes revealed minimal historical and contemporary admixture between coyotes and dogs. We observed only mutually exclusive mtDNA haplotypes in coyotes and dogs, but we observed Y-chromosome haplotypes (Y-haplotypes) in both historical and contemporary coyotes that were also common in dogs. Species-specific Zfy intron sequences of Y-haplotypes shared between coyotes and dogs ... : Wheeldon et al ECE3_693 Autosomal Microsatellite DataAutosomal microsatellite genotypes of historical (pop 1) and contemporary (pop 2) coyotes from southeastern Ontario, eastern wolves (pop 3) from Algonquin Provincial Park, gray wolves (pop 4) from northeastern Ontario, and domestic dogs (pop 5).Wheeldon et al ECE3_693 DRYAD entry.xlsx ... |
