    Abstract:
    Nucleotide sequences of the mitochondrial DNA (mtDNA) control region were studied in Germans living in the Altai, Russia. Although this ethnic group has been living in Russia for a long time, the obtained data indicate that its mitochondrial gene pool retains the main characteristics of the Western and Central European gene pools. Regarding the mitochondrial gene pool, Russian Germans were more similar to Germans living in Germany than to Russians with regard to the frequency of the Cambridge nucleotide sequence, frequencies and composition of five European haplotypic groups (classification of Richards et al.), and average intra- and interpopulation pairwise nucleotide differences. However, the mitochondrial gene pool of Altaian Germans also differed from that of Western European populations. The gene pool of Altaian Germans contained the ancestral variants of the main haplotypic groups. To date, these variants have not been found in modern Western and Central European populations, which is apparently due to their lower frequencies. In addition, some previously unknown mtDNA variants with specific nucleotide substitutions were found in Altaian Germans. The obtained results suggest that the modern mitochondrial gene pool of Europeans, including Germans from Germany, was largely affected by the demographic processes that occurred in the past two centuries. The Germans that lived in Russia were relatively isolated and, hence, retained more characteristics of the ancestral gene pool.
