Depending on the geographical location of samples, West Eurasian mtDNA haplogroup lineages make up 27% to 42.6% in the Kyrgyz, with haplogroup mtDNA H being the most predominant West Eurasian mtDNA haplogroup at about 14.2% (range 8.3% Talas to 21.3% Sary-Tash) among the Kyrgyz. However, the majority of Kyrgyz belong to East Eurasian mtDNA haplogroups, with mtDNA haplogroup D (approx. 20.2%, range 14.6% Talas to 25.5% Sary-Tash) and D4 in particular (approx. 18.5%) being the most frequent Eastern Eurasian lineage among them.Table 2 in thumb|A Eurasian-wide Principal Component Analysis of the modern and ancient Eurasians. A total of 1,372 ancient individuals are projected onto the first two principal components defined by modern Eurasian populations. (A) Mesolithic to Eneolithic Age, (B) Pre-Bronze to Bronze Age, (C) Iron Age and (D) Historical Era individuals were shown. Kyrgyz people are shown in the center between East and West-Eurasian clusters. A 2011 study of autosomal ancestry found that East Eurasian ancestry is predominant in most Kyrgyz living in Kyrgyzstan. East Eurasian ancestry makes up roughly two-thirds with exceptions of Kyrgyz living in Tajikistan and the western areas of Kyrgyzstan, where it forms only half.
