The gene pool of the Belgorod oblast population: II. “Family name portraits” in groups of districts with different degrees of subdivision and the role of migrations in their formation
AbstractThe frequencies and spectra of surnames have been analyzed in groups of raions (districts) of the Belgorod oblast (region) with different degrees of population subdivision. The “family name portraits” of districts with low (0.00003 < < f*r < 0.00022, 
$$\overline {f_r^ * } $$
 = 0.00015) and moderate (0.00023 < f*r < 0.00042, 
$$\overline {f_r^ * } $$
 = 0.00029) inbreeding levels are similar both to each other and to the “family name portrait” of the Belgorod oblast as a whole. Districts with high subdivision levels (0.00043 < f*r < 0.00125, 
$$\overline {f_r^ * } $$
 = 0.00072) had very distinctive surname spectra and the highest surname frequencies. Intense immigration to the Belgorod oblast significantly affects its population genetic structure, decreasing the population subdivision.
The gene pool of the Belgorod oblast population: Description of the “genetic landscape” of 22 district populations
Data on the frequencies of all (50412) surnames in a total population of 849399 people have been treated by various methods of multivariate statistics (cluster analysis, multidimensional scaling, and factor analysis) to show that 22 district populations of the Central Chernozem region of Russia form a definite, ordered system of population groups. All raions (administrative districts) of Belgorod oblast (administrative region) have been grouped into four clusters corresponding to the actual geographic locations of the populations. Districts of the eastern cluster are characterized by very specific spectrum and frequencies of surnames; districts of the western cluster differ in a high proportion of Ukrainian surnames
Material for Studying the Gene Pools of Russia and Neighboring Countries: The Russian Population of the Pskov Oblast
The distributions of the genes and haplotypes for blood groups AB0, MN, Rhesus, P1, Lewis, and Kell–Cellano and biochemical markers of the genes of loci HP, GC, C"3, TF, 6PGD, GLO1, ESD, ACP1, and PGM1(including subtypes) were studied in 116 Russian subjects born in the Pskov oblast. Differences of this group from other Russian populations with respect to genetic structure were found.
