Nearly all dog breeds’ genetic closeness to the gray wolf is due to admixture. However, several Arctic dog breeds show a genetic closeness with the now-extinct Taymyr wolf of North Asia due to admixture. These breeds are associated with high latitudes – the Siberian Husky and Greenland dog that are also associated with arctic human populations and to a lesser extent, the Shar Pei and Finnish spitz. An admixture graph of the Greenland dog indicates a best-fit of 3. 5% shared material, however an ancestry proportion ranging between 1. 4% and 27. 3% is consistent with the data. This indicates admixture between the Taymyr wolf population and the ancestral dog population of these 4 high-latitude breeds. This introgression could have provided early dogs living in high latitudes with phenotypic variation beneficial for adaption to a new and challenging environment. It also indicates the ancestry of present-day dog breeds descends from more than one region.
