Restriction polymorphism of mitochondrial DNA (mtDNA) isolated from the blood of 107 Koryaks, 28 Northern Altaians, and 23 Kets was studied. The results were compared with similar data that in aggregate characterized haplotypes of 569 individual DNAs from 13 Siberian populations, in order to elucidate the genetic similarity and differences between mtDNA haplogroups of native Siberians and Americans. Natives of Siberia are distinguished by the significant variation of the composition and frequency of three (A, C, and D) of four haplogroups characteristic of American Indians. In the full composition, all four haplogroups-A, B, C, and D-are found only in a sample of Northern Altaians. The peculiarities of their geographical distribution in Asia allow us to consider the southern regions of Siberia and the adjacent territories of Central and East Asia as the site inhabited by the ancestors of the first wave of migrants to North America.
对从107名科里亚克人、28名北阿尔泰人以及23名凯特人的血液中分离出的线粒体DNA（mtDNA）的限制性多态性进行了研究。将结果与来自13个西伯利亚人群的569个个体DNA单倍型的综合特征的类似数据进行了比较，以阐明西伯利亚原住民和美洲人线粒体DNA单倍群之间的遗传相似性和差异。西伯利亚原住民的特点是美洲印第安人特有的四个单倍群中的三个（A、C和D）的组成和频率有显著变化。在完整的组成中，所有四个单倍群——A、B、C和D——仅在北阿尔泰人的样本中发现。它们在亚洲的地理分布特点使我们能够将西伯利亚南部地区以及中亚和东亚的相邻地区视为第一批移民到北美祖先居住的地方。
