蒙古国境内约有20个民族。根据遗传学和人类学研究，蒙古人在中亚和东亚的人口中发挥了关键作用。然而，这些种族群体之间的遗传关系仍然模糊，他们与邻近人群的详细关系也是如此。我们分析了16个二元和17个STR多态性的人类Y染色体669人从9个群体，包括4个土著民族在蒙古国（哈尔克，乌连海，扎赫钦，和Khoton）。在这四个蒙古种群中，Khalkh，Uriankhai和Zakhchin种群彼此之间以及与西伯利亚种群的遗传亲缘关系相对较近，而Khoton种群与中亚种群的关系比其他蒙古种群更近。这些研究结果表明，蒙古族的主要族群有一个密切的遗传亲和力的人口在北方东亚，虽然蒙古和中亚之间的遗传联系是不可忽视的。(c)2004 Elsevier B.V.保留所有权利。
About 20 ethnic groups reside in Mongolia. On the basis of genetic and anthropological studies, it is believed that Mongolians have played a pivotal role in the peopling of Central and East Asia. However, the genetic relationships among these ethnic groups have remained obscure, as have their detailed relationships with adjacent populations. We analyzed 16 binary and 17 STR polymorphisms of human Y chromosome in 669 individuals from nine populations, including four indigenous ethnic groups in Mongolia (Khalkh, Uriankhai, Zakhchin, and Khoton). Among these four Mongolian populations, the Khalkh, Uriankhai, and Zakhchin populations showed relatively close genetic affinities to each other and to Siberian populations, while the Khoton population showed a closer relationship to Central Asian populations than to even the other Mongolian populations. These findings suggest that the major Mongolian ethnic groups have a close genetic affinity to populations in northern East Asia, although the genetic link between Mongolia and Central Asia is not negligible.
