Abstract
In the past two decades, studies of Y chromosomal single nucleotide polymorphisms (YSNPs)
and short tandem repeats (Y-STRs) have shed light on the demographic history of Central Asia,
the heartland of Eurasia. However, complex patterns of migration and admixture have complicated
population genetic studies in Central Asia. Here, we sequenced and analyzed the Y-chromosomes
of 187 male individuals from Kazakh, Kyrgyz, Uzbek, Karakalpak, Hazara, Karluk, Tajik, Uyghur,
Dungan, and Turkmen populations. High diversity and admixture from peripheral areas of Eurasia
were observed among the paternal gene pool of these populations. This general pattern can be
largely attributed to the activities of ancient people in four periods, including the Neolithic farmers,
Indo-Europeans, Turks, and Mongols. Most importantly, we detected the consistent expansion of
many minor lineages over the past thousand years, which may correspond directly to the formation
of modern populations in these regions. The newly discovered sub-lineages and variants provide a
basis for further studies of the contributions of minor lineages to the formation of modern populations
in Central Asia.
