| [genetic divergence of vipera berus and vipera nikolskii (reptilia: viperidae, vipera) populations in lower volga and adjacent territories assessed according to the sequences of cytochrome oxidase iii 12s ribosome rna genes]. | the nucleotide sequences of mitochondrial genome fragments containing the genes coding for cytochrome oxidase subunit iii (coiii) and 12s ribosomal rna of common european viper and nikolsky's viper from various habitats (saratov, samara, and penza oblasts; chuvash republic; and the republic of mordovia) were determined. according to the sequencing data, all samples clustered into two groups except for a number of individuals carrying single mutations in the genes in question. one group comprised ... | 2008 | 18619049 |
