Y chromosome haplotype distribution of brown bears ( Ursus arctos ) in Northern Europe provides insight into population history and recovery
Abstract High‐resolution, male‐inherited Y‐chromosomal markers are a useful tool for population genetic analyses of wildlife species, but to date have only been applied in this context to relatively few species besides humans. Using nine Y‐chromosomal STRs and three Y‐chromosomal single nucleotide p...
