[Genetic demographic structure of rural populations of Kyrgyzstan].

The genetic demographic parameters of rural populations of Kyrgyzstan have been studied. The rural population of Kyrgyzstan has the following demographic characteristics: (1) it is demographically young (the population mean age is 25-28 years); (2) the sex ratio in reproductive age groups is unfavorable; (3) the fertility is high (5.78-7.

[Haplotype of Y-chromosomes in the Central Asia population].

The distribution of alleles and haplotypes of three diallellic Y-specific loci (YAP, DYF155S2, and Tat) in the populations of Kyrgyz, Uzbeks and Tajiks was analyzed. In Kyrgyzes and Uzbeks, a relatively high frequency of the DYF155S2 deletion (20 and 12.5%, respectively) and the C allele at the Tat locus (11.
