| Abstract: | An extremely limited haplotypic diversity within populations and a strikingly low divergence between European and Canadian haplotypes were found in pike Esox lucius . Certain haplotypes were associated with a particular geographical region in Europe: a widespread European and a restricted Hungarian–Norwegian type. The low haplotypic intraspecific divergence suggests a late Pleistocene expansion from an ancestral population. |
