An analysis of allozyme, mitochondrial DNA and morphological variation in mussel (Mytilus galloprovincialis) populations from Greece

Three populations of Mytilus galloprovincialis from northern Greece were investigated using isozyme analysis, discriminant analysis of morphological characteristics and analysis of restriction fragments of mtDNA. For all three types of analysis significant intra- and interpopulation differentiation was found. This differentiation is very noticeable at the mtDNA genotype frequencies. The restriction patterns of mtDNA were different from those reported for Atlantic populations of this species.
