Data from: Contemporary factors influencing genetic diversity in the Alaska humpback whitefish Coregonus clupeaformis complex
Thirteen microsatellite loci were used to address three hypotheses regarding genetic diversity in the humpback whitefish Coregonus clupeaformis complex in Alaska. The test results provided further insight into the factors influencing C. clupeaformis complex population structure and level of genetic...
