In 2015, a study using a number of genetic markers indicated that the Siberian Husky, the Alaskan Malamute and the Alaskan husky share a close genetic relationship between each other and were related to Chukotka sled dogs from Siberia. They were separate to the two Inuit dogs, the Canadian Eskimo Dog and the Greenland Dog. In North America, the Siberian Husky and the Malamute both had maintained their Siberian lineage and had contributed significantly to the Alaskan husky, which showed evidence of crossing with European breeds that were consistent with this breed being created in post-colonial North America.
