Genetic relationships and evolutionary history of extant Bowhead whale populations, Balaena mysticetus
Bowhead whales, Balaena mysticetus, are large baleen whales that are characterized by an Arctic distribution. In order to provide proper management recommendations to the International Whaling Commission, a panel of twenty-five microsatellite markers was developed. This panel consisted of pure cytos...
