Figure 4. Comparison of the genetic and linguistic trees of North Caucasus populations.

Figure 4

The genetic tree was constructed from frequencies of 28 Y-chromosomal haplogroups in North Caucasus populations (data from Table 2). Populations speaking the same language (three Chechen populations and two Ossetian ones) were pooled to make the genetic dataset compatible with the linguistic classification. The weighted pair-group method was used as a clustering algorithm. The linguistic tree represents the classification of the North Caucasian languages from classical work (Ruhlen, 1987). Kubachi and Kaitak (languages of small populations) were not listed in Ruhlen’s classification, but most linguists agree that they are most related to the Dargin language.
