A study of genetic variation in northeast Atlantic harp seals (Pagophilus groenlandicus)
16 enzymes were examined for genetic studies of the harp seal population structure in the Northeast Atlantic. Muscle and liver samples were collected in the West Ice off Jan Mayen and in the Eastern Barents Sea in 1987, 1989 and 1990. The samples were analyzed by starch gel electrophoresis and isoel...
