Abstract
This work analyzed a large volume of literature on the genetic diversity of Azerbaijanis. Data from these sources were systematized and grouped, and a general description of trends in the distribution of Y-DNA and mt-DNA haplogroups was given. For the first time, the data of Azerbaijan DNA Project at FTDNA were used and on their basis the general statistical characteristics of the diversity of patrilineal and matrilineal gene pools were described. All information received within the Azerbaijan DNA Project at FTDNA was combined and brought together with data from various scientific sources. We made an attempt to summarize data on the distribution of patrilineal haplogroups in Azerbaijanis from some of the most informative sources with data from FTDNA. The subclades in question were designated according to the Yfull classification. The results of the work were analyzed using the M. D. Kendall coefficient of concordance. Kendall's coefficient of consistency was W=0.83, which indicates a high degree of consistency between the data of different authors at a significance level of α=0.01. Taking these results into account, we have compiled a diagram of the diversity of Y-DNA haplogroups of the generalized sample of Azerbaijanis, which is currently the most presentable for characterizing patrilineal haplogroups.
Highlights
The genetic diversity of the population of the Caucasus in general and Azerbaijan in particular has recently been actively studied and discussed in various scientific circles [15]
The work analyzed the data of 12 authors on the diversity of haplogroups in the patrilineal part of the gene pool, as well as on the polymorphism of the HVR1 and HVR2mt-DNA segments, which were obtained during the study of biomaterials taken from the Azerbaijanis [1,2,3,4, 6, 7, 10,11,12,13, 17]
In addition to problems with the nomenclature and the lack of data on the classifications used by individual authors, in many cases it was necessary to deal with incomplete identifications of haplogroups
Summary
The genetic diversity of the population of the Caucasus in general and Azerbaijan in particular has recently been actively studied and discussed in various scientific circles [15]. Quite extensive factual material has been accumulated that requires analysis and interpretation. Close acquaintance with these works made it possible to establish that many works duplicate each other. Cruciani et al [6] in their work devoted to the phylogenographic analysis of haplogroup E3b, refer to materials from the work of a group of scientists R. Malaspina et al [7], which contain information about the prevalence of some haplogroups among Azerbaijanis. This can be found in the article of Iranian scientists, who used the data of their compatriots published earlier as materials [8]
