Genetic characterization of Kenai brown bears (Ursus arctos): microsatellite and mitochondrial DNA control region variation in brown bears of the Kenai Peninsula, south central Alaska

摘要: We collected data from 20 biparentally inherited microsatellite loci, and nucleotide sequence the maternally mitochondrial DNA (mtDNA) control region, to determine levels of genetic variation brown bears (Ursus arctos L., 1758) Kenai Peninsula, south central Alaska. Nuclear was similar that observed in other Alaskan peninsular populations. detected no significant inbreeding found evidence population substructuring on Peninsula. a signature bottleneck under infinite alleles model (IAM), but not stepwise mutation (SMM) or two-phase (TPM) mutation. have lower mtDNA haplotypic diversity relative most bear populations
