Summary of the results of the ancestry blocks analyses in lamp for Eurasian wolf populations, North American wolves populations and pure‐bred dogs, in comparison with the results of tests based on the analysis of population genetic structure (using structure and admixture, assuming K = 2)

Number of samples is provided in brackets after the name of each population. lamp results are presented as the percentage of SNP alleles of wolf ancestry in autosomal chromosomes (at average) and in X chromosome (assessed only for individuals with sex known a priori and separately for males and females). We also report the number of admixed autosomal chromosomes, that is, having less than 90% of SNP alleles of wolf ancestry. The results of structure and admixture analyses are presented as the assignment probability of a given individual to the wolf cluster. “North American wolves” denote all North American wolf populations except Mexican wolves, which are presented separately. North American wolves were analysed in a separate lamp run rather than with Eurasian wolves.
