Y-DNA haplogroups in populations of the Caucasus

(Learn how and when to remove this message)

Various Y-DNA haplogroups have differing frequencies within each ethnolinguistic group in the Caucasus region.

Table

The table below lists the frequencies – identified by major studies – of various haplogroups amongst selected ethnic groups from the Caucasus. The first two columns list the ethnic and linguistic affiliations of the individuals studied, the third column gives the sample size studied, and the other columns give the percentage of the particular haplogroup.

Language family abbreviations:
IE Indo-European
NEC Northeast Caucasian
NWC Northwest Caucasian
Kartvelian South Caucasian
