The nucleotide sequence of the VD1 domain of the Long Unassigned Region in the F mitochondrial DNA genome was studied for 135 Iberian mussels, 78 from the Atlantic and 57 from the Mediterranean. Significant genetic differentiation between Atlantic and Mediterranean Mytilus galloprovincialis samples was found (F ST = 0.262, P < 0.00001). The four main clusters observed in the neighbor‐joining tree of haplotypes were not exclusive for a specific region, but a clear geographic pattern could be observed. One of the clusters contained 86% of the Atlantic individuals and the remaining three clusters were predominantly Mediterranean. The Atlantic–Mediterranean differentiation of the mitochondrial DNA haplotypes was in agreement with previous data describing the same partitioning in M. galloprovincialis and in many other marine organisms, using different kinds of genetic markers. In all cases the Almeria Oran Oceanographic front has been associated to this genetic discontinuity.
