Population genetic analysis of the population of Luhansk oblast

Abstract

Aim. The aim was to analyze the population of Luhansk region and to investigate the possibility of surnames to differentiate populations at the district level. Methods. The general population census database of Luhansk oblast was used. Calculations of indicators of the population structure of the regional and eighteen district populations were carried out according to I. Barrai. Results. The structure of the Luhansk regional population is characterized by the isonymy index І (2.4×10-4), the FST inbreeding coefficient (6.0×10-5), the migration index v (18.7×10-4), the diversity index a (41.7×102), entropy H (14.6) and surname redundancy R (31.0). Indicators of district populations vary widely: I from 3.5×10-4 in the industrial areas of the south of the region to 23.7×10-4 in the north. The FST is in the range 8.7–59.3×10-5, v — 69.3–241.9×10-4, a — 4.3–29.0×102, H — 9.7–13.4, R — 24.1–30.2. Conclusions. The results obtained with the surnames testify to the significant impact of human economic activity on the population structure, which is reflected in isonymy, inbreeding and migration.
