| Summary: | Liver and muscle tissue collected from harp seals ( Phoca groenlandica ) in the Newfoundland area were analysed by isoelectric focusing of five known variable enzyme systems. Allele frequencies were compared with corresponding frequencies previously recorded in north-east Atlantic samples. Muscle tissue collected from harp seals in the White Sea area and the Greenland Sea were analysed by DNA-fingerprinting. Samples were compared using band-sharing coefficients. Frequency distributions in AAT-2 and ME-1 were significantly different from those previously found in samples collected in the north-east Atlantic. Accordingly, it seems justified to divide the total stock of harp seals into one eastern and one western component. Highly variable profiles of Pal I digested genomic DNA were revealed using the human minisatellite 33.15 hybridization probe. Intra- and inter-population average band-sharing coefficients were uniformly low (range: 0.111–0.116). DNA-ingerprinting analyses did not reveal evidence for genetic differentiation between White Sea and Greenland Sea harp seals. |
