[Polymorphism of biochemical markers in European bison (bison bonasus)].

The data on 16 polymorphic systems (22 loci) of blood biochemical markers were studied in different breeding lines of European bison: Lowland, Lowland-Caucasian, and Mountain lines. Polymorphism was revealed in three loci: Pgm, Idh, and Tf. The average heterozygosity was 3.

[Blood group polymorphism in bison (Bison bonasus)].

Polymorphism of nine blood group systems was studied in three reproductive lines of auroch (European bison Bison bonasus), Belovezhskaya, Caucasian-Belovezhskaya, and Gornaya. All blood group systems analyzed were polymorphic; 50 out of the 57 antigens tested were detected. The number of detected blood group antigens in aurochs is comparable to that in breeds of domestic cattle.

[Genetic polymorphism of the HLA system in Komi and Komi-Permyaks].

High frequencies of HLA-A2, -A3, -A9, -B7, -B13, -Bw35, and -Dw3 antigens were found in Sysolian and Udorian Komi (from Vizinga and Koslan, respectively), as well as in Zyuzdian Komi-Permyaks. In some populations, high frequencies of HLA-A10, -A28, -B21, -B27, and -B40 antigens were also found. Similarity in both gene frequency patterns and heterozygosity level was noted between these populations and the population of more western European regions, as well as Finno-Ugric nations.

[Migration structure and inbreeding in the Talysh population].

The origin of genes in Talysh population (South Azerbaijan Republic) is considered. During 11 generations of population history more than 100 unrelated persons supplied the genes to the population. At present, the population is highly isolated: the endogamy index is 0.
