A minisatellite DNA marker for discriminating between European and North American Atlantic salmon (Salmo salar)
A highly discriminatory and practical nuclear DNA genetic marker that can distinguish between Atlantic salmon (Salmo salar) of European and North American origin is described. Screening of 2847 European and 247 North American Atlantic salmon from much of its geographic range for variability at a min...
