Allozyme variability was assessed, using starch gel electrophoresis, at 15 polymorphic loci in two samples of the Pacific mussel Mytilus trossulus collected from local populations in heavily (Golden Horn Bay) and slightly polluted areas (Sukhoputnaya Bay) of Peter the Great Bay. Significant differences between samples were found in the genotypic frequencies at nine loci and in allele frequencies, at six loci. The results are suggestive of the differential survival of individuals having different genotypes and alleles at some of the surveyed loci under conditions of pollution. Our data are not in conflict with the hypothesis of the adaptive significance of allozyme polymorphism.
