Stock-specific differences in the number and chromosome positions of the nucleolar organizer regions in arctic char (Salvelinus alpinus)
Stock-specific variation in the number and chromosome locations of the nucleolar organizer regions (NORs) was found in North American and European stocks of arctic char ( Salvelinus alpinus) using chromomycin A 3 staining and silver staining. The number of NORs varied from two to eight per diploid g...
