The Gagauz are a Turkic-speaking group that migrated from Turkey to their present location in the southern part of the Republic of Moldova about 150 years ago. Surrounded by Indo-European-speaking populations, they thus form a linguistic enclave, which raises the following question: to what extent have they remained in genetic isolation from their geographic neighbours? Analyses of mtDNA and Y chromosome variation indicate that despite their linguistic differences, the Gagauz have admixed extensively with neighbouring groups. Our data suggest that there has been more mtDNA than Y chromosome admixture, in keeping with the patrilocal nature of these groups. Moreover, when compared with another linguistic enclave, the Kalmyks there appears to be a correlation between the amount of genetic admixture and the amount of linguistic influence that these two linguistic enclaves have experienced from neighbouring groups.
加告兹人是一个说突厥语的群体，大约150年前从土耳其迁徙到他们现在位于摩尔多瓦共和国南部的所在地。由于被说印欧语的人群包围，他们因此形成了一个语言飞地，这就引出了以下问题：他们在多大程度上与地理上的邻居保持着基因隔离？对线粒体DNA（mtDNA）和Y染色体变异的分析表明，尽管加告兹人存在语言差异，但他们与相邻群体有广泛的混合。我们的数据表明，线粒体DNA的混合比Y染色体的混合更多，这与这些群体的父系居住性质相符。此外，与另一个语言飞地卡尔梅克人相比，这两个语言飞地从相邻群体那里经历的基因混合量与语言影响量之间似乎存在相关性。
