Allozyme variation in a population of the common mussel Mytilus edulis in Mumbles, South Wales, has been studied by starch gel electrophoresis. On the basis of data obtained for 34 loci, we estimate the proportion of loci polymorphic to be 30%. Using only the 29 loci for which individual genotypes can be accurately typed, the average heterozygosity is estimated to be 9.5 +/- 3.6%. The calculated expected average heterozygosity based on Hardy-Weinberg expectations is identical with the observed value. Allele frequency data at six polymorphic loci are given for several other British populations. There is no significant geographic heterogeneity. The results are discussed in relation to genetic adaptive strategies and are shown to be inconsistent with the predictions of the neutral hypothesis.
通过淀粉凝胶电泳研究了南威尔士芒布尔斯普通贻贝紫贻贝种群中的等位酶变异。根据34个基因座获得的数据，我们估计多态性基因座的比例为30%。仅使用29个能够准确分型个体基因型的基因座，估计平均杂合度为9.5±3.6%。基于哈迪-温伯格预期计算的预期平均杂合度与观察值相同。给出了其他几个英国种群在六个多态性基因座上的等位基因频率数据。没有显著的地理异质性。结合遗传适应策略对结果进行了讨论，结果表明与中性假说的预测不一致。
