Abstract
    Allozyme variation in a population of the common mussel M. edulis in Mumbles, South Wales, has been studied by starch gel electrophoresis. On the basis of data obtained for 34 loci, it is estimated the proportion of loci polymorphic to be 30%. Using only the 29 loci for which individual genotypes can be accurately typed, the average heterozygosity based on Hardy-Weinberg expectations is identical with the observed value. Allele frequency data at 6 polymorphic loci are given for several other British populations. There is no significant geographic heteogeneity. The results are discussed in relation to genetic adaptive strategies and are shown to be inconsistent with the predictions of the neutral hypothesis.
