Y‐chromosome evidence supports asymmetric dog introgression into eastern coyotes

摘要: Hybridization has played an important role in the evolutionary history of Canis species eastern North America. Genetic evidence coyote–dog hybridization based on mitochondrial DNA (mtDNA) is lacking compared to that autosomal markers. This discordance suggests dog introgression into coyotes potentially been male biased, but this hypothesis not formally tested. Therefore, we investigated biparentally, maternally, and paternally inherited genetic markers a sample dogs from southeastern Ontario assess potential asymmetric coyotes. Analysis microsatellite genotypes revealed minimal historical contemporary admixture between dogs. We observed only mutually exclusive mtDNA haplotypes dogs, Y-chromosome (Y-haplotypes) both were also common Species-specific Zfy intron sequences Y-haplotypes shared confirmed their homology indicated putative origin coyotes, wolves, profiled multiple studies, either absent or rare American present western suggest coyote experienced resulting predominantly with subsequent backcrossing hybrid offspring discuss temporal spatial dynamics conditions may have facilitated Y-chromosomes Our findings clarify coyote.
