Six Y-linked short-tandem-repeat (STR) loci were analyzed in 300 male gray wolves from six populations in North America. These comprised three subspecies from Alaska, Western Canada and the Eastern, Western and Southwestern Distinct Population Segments (DPS) designated by the USFWS under the Endangered Species Act, and included individuals from both the Northern US Rockies and Mexican wolf experimental reintroduction populations. The results were compared with 237 base pairs of mtDNA control region (CR) sequence and data from 10 autosomal STR loci obtained from the same individuals in order to study possible differences in male versus female patterns of genetic variation. Y-STR haplotype diversity was higher than mtDNA genetic diversity in all six populations with at least fourteen Y-STR haplotypes being exclusive to single populations. While four mtDNA CR haplotypes were commonly observed across all North American wolf populations, except Southwestern wolves, a fifth haplotype was unique to Western wolves and a sixth distinguished Southwestern wolves from all others. Two mtDNA CR haplotypes, commonly observed and exclusive to Eastern wolves, were most similar, but not identical, to those of coyotes.
