Popis: DNA samples were obtained from six charr species: Salvelinus alpinus, S. malma, S. confluentus, S. leucomaenis, S. namaycush and S. fontinalis and two outgroups: Salmo salar and S. trutta. The C and D introns from the duplicate growth hormone loci (GH1 and GH2) were amplified using the polymerase chain reaction and sequenced from each of the species. Phylogenetic analyses with and without gaps were performed using the beta version of PAUP. The GH introns are evolving relatively slowly, so the data were combined with sequences from the ITS1 and ITS2 for a phylogenetic analysis of the charr species. The GH intron data and the combined data supported two groups of sister species among charrs: S. alpinus and S. malma, and S. confluentus and S. leucomaenis.
