Screen for footprints of selection during domestication/captive breeding of Atlantic salmon. Comp Funct Genom 2012
Domesticated animals provide a unique opportunity to identify genomic targets of artificial selection to the captive environment. Here, we screened three independent domesticated/captive Atlantic salmon (Salmo salar) strains and their wild progenitor populations in an effort to detect potential sign...
