先前对高加索地区线粒体DNA变异的分析发现，讲印欧语的亚美尼亚人和讲突厥语的阿塞拜疆人分别与其他高加索人群(说高加索语言)的遗传关系比与其他印欧或突厥语群体的亲缘关系更密切。因此，亚美尼亚人和阿塞拜疆人代表着语言的替代，可能是通过主要涉及男性移民的精英统治，在这种情况下，亚美尼亚人和阿塞拜疆人基于Y染色体的遗传关系应该更密切地反映他们的语言关系。因此，我们分析了来自8个群体的389名男性的11个双等位Y染色体标记，这些标记代表了高加索地区所有主要的语言群体。与线粒体DNA研究一样，基于Y染色体，亚美尼亚人和阿塞拜疆人在基因上与高加索地区的地理邻居的亲缘关系比与其他地方的语言邻居的亲缘关系更密切。然而，尽管mtDNA结果显示高加索人群体在遗传上与欧洲人的关系比与近东人的关系更近，但相比之下，Y染色体显示出与近东人的遗传关系比与欧洲人的关系更近。
A previous analysis of mtDNA variation in the Caucasus found that Indo-European-speaking Armenians and Turkic-speaking Azerbaijanians were more closely related genetically to other Caucasus populations (who speak Caucasian languages) than to other Indo-European or Turkic groups, respectively. Armenian and Azerbaijanian therefore represent language replacements, possibly via elite dominance involving primarily male migrants, in which case genetic relationships of Armenians and Azerbaijanians based on the Y-chromosome should more closely reflect their linguistic relationships. We therefore analyzed 11 bi-allelic Y-chromosome markers in 389 males from eight populations, representing all major linguistic groups in the Caucasus. As with the mtDNA study, based on the Y-chromosome Armenians and Azerbaijanians are more closely-related genetically to their geographic neighbors in the Caucasus than to their linguistic neighbors elsewhere. However, whereas the mtDNA results show that Caucasian groups are more closely related genetically to European than to Near Eastern groups, by contrast the Y-chromosome shows a closer genetic relationship with the Near East than with Europe.
