Mitochondrial DNA (mtDNA) variation was studied using restriction enzyme analysis in samples of mussels (Mytilus) from three British populations. The first sample obtained from Swansea Bay, South Wales consisted of Mytilus edulis L. The second sample from the Padstow estuary in Cornwall was of individuals of the M. galloprovincialis Lamarck form. The third sample was from Croyde Bay in North Devon where on the basis of allozyme and morphological evidence hybrid individuals occur. Evidence was found of distinct mtDNA differences between the Swansea Bay and Padstow samples. The sample from Croyde Bay contained genotypes found at both Swansea Bay and Padstow, thus providing corroborative evidence for the hybrid nature of this population.
