Cub adoption by polar bears ( Ursus maritimus): determining relatedness with microsatellite markers
Abstract Sixteen microsatellite markers were used to determine the genetic relatedness between adult female polar bears and their accompanying cubs for three recent occurrences of natural adoption recorded in the Canadian Arctic. The estimation of the degree of relatedness was powerful and provided...
