Nearly all dogs' genetic closeness to the gray wolf is due to admixture.[6] However, several Arctic breeds also show a genetic closeness with the now-extinct Taimyr wolf of North Asia due to admixture: the Siberian husky and Greenland dog (which are also historically 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 and indicates admixture between the Taimyr wolf and the ancestors these four high-latitude breeds.
