Genetic variability and relationships of populations of the cockles Cerastoderma edule and of the C. glaucum complex in Europe were determined by means of isoenzyme electrophoresis. Distinct isoenzyme markers allowed a clear distinction between these two taxa. C. edule showed a higher genetic intra-population variability than the other cockle species. The imbalance of the genotypes within populations and the inter-population differentiation of the C. glaucum complex are stronger than in C. edule. The genetic variability is related to the different habitats of the species, the members of the C. glaucum complex living in more isolated areas and having more limited gene flow.
