Directional selection against different life histories in the Arctic lamprey ( Lethenteron camtschaticum ): identification by microsatellite analysis
To understand the selective forces promoting life history evolution in lampreys, footprints of natural selection were identified using the hitchhiking mapping approach for microsatellite loci. To achieve the objective, the Arctic lamprey (Lethenteron camtschaticum), including anadromous and recently...

To understand the selective forces promoting life history evolution in lampreys, footprints of natural selection were identified using the hitchhiking mapping approach for microsatellite loci.
