Assignment probabilities of individuals to the three genetic clusters estimated in Structure.

For admixed individuals, mtDNA haplotypes, the species they match with (see the comment in the Supplementary Information) and GenBank accession numbers, as well as probable admixture status are also provided. Haplotype w4 was found in both grey wolves and domestic dogs. ‘Misidentified jackal’ is an individual sampled as a grey wolf that clusters with golden jackals and carries a golden jackal mtDNA haplotype.
