A genetic assessment of single versus double origin of landlocked Atlantic salmon ( Salmo salar ) from Lake Saint-Jean, Québec, Canada
We assessed the genetic relationships among landlocked populations and parapatric anadromous populations of Atlantic salmon (Salmo salar) from the Saguenay River system to infer the alternative scenarios of single versus double origin of salmon in Lake Saint-Jean, Québec, Canada. We predicted that t...
