title: Genetic variation at enzyme loci in North Atlantic minke whales, Balaenoptera acutorostrata.
abstract: Electrophoretic variation within and between North Atlantic minke whale samples (Balaenoptera acutorostrata) from West Greenland, Iceland, and Norway was investigated. In the West Greenland samples, 28 enzyme systems were examined, representing 36 loci, of which 6 were found to be polymorphic. In Icelandic and Norwegian samples, 22 enzyme systems were examined, representing 29 loci, of which 6 and 5 were found to be polymorphic, respectively. The average heterozygosity was 0.058 (SE = 0.024) in samples from West Greenland, 0.074 (SE = 0.028) in samples from Iceland, and 0.054 (SE = 0.023) in samples from Norway. No significant deviations from the expected Hardy-Weinberg genotypic frequencies, within samples taken from the same area, were found. Significant differences in allele frequencies were observed, however, between samples from the three different areas. The average Nei's genetic distance was 0.014 and the average Fst value was 0.126. The genetic differences between the samples from the different areas indicate that those from West Greenland, Iceland, and Norway represented different breeding populations.
