Última Maintenance of genetic differentiation across a transition zone in the sea: discordance between nuclear and cytoplasmic markers ArchiMer Lemaire, Christophe; Versini, J; Bonhomme, Francois. To investigate the origin and maintenance of the genetic discontinuity between Atlantic and Mediterranean populations of the common sea bass (Dicentrarchus labrax) we analysed the genetic variation at a fragment of mitochondrial cytochrome b sequence for 18 population samples. The result were also compared with new or previously published microsatellite data. Seven mitochondrial haplotypes and an average nucleotidic divergence of 0.02 between Atlantic and Mediterranean populations that matches a Pleistocene allopatric isolation were found. The frequency variation at the cytochrome b locus was many times greater between Atlantic and Mediterranean populations ((θ) over cap (C) = 0.67) than at microsatellite loci ((θ) over cap (N) = 0.02)....
