“…The lowest level of polymorphism was observed for the marker REN247M23, with a PIC value of 0.543. A study of 28 borzoi dogs also revealed one of the lowest levels of polymorphisms of this marker, with a PIC PLOS ONE value of 0.590 [32]. We also found the lowest heterozygosity for this marker (Ho = 0.518).…”

“…The highest level of polymorphism was observed at the REN169D01 and AHT121 loci, where the PIC value exceeded 0.850. An equally high degree of polymorphism of these markers was found in 28 Borzoi dogs in Poland (PIC = 0.756 and 0.732, respectively) [32]. The lowest level of polymorphism was observed for the marker REN247M23, with a PIC value of 0.543.…”

The Tazy or Kazakh National sighthound has been officially recognized as the national heritage of Kazakhstan. Comprehensive genetic studies of genetic diversity and population structure that could be used for selection and conservation of this unique dog breed have not been conducted so far. The aim of this study was to determine the genetic structure of the Tazy using microsatellite and SNP markers and to place the breed in the context of the world sighthound breeds. Our results showed that all 19 microsatellite loci examined were polymorphic. The observed number of alleles in the Tazy population varied from 6 (INU030 locus) to 12 (AHT137, REN169D01, AHTh260, AHT121, and FH2054 loci) with a mean of 9.778 alleles per locus. The mean number of effective alleles was 4.869 and ranged from 3.349 f to 4.841. All markers were highly informative (PIC values greater than 0.5) and ranged from 0.543 (REN247M23 locus) to 0.865 (AHT121 locus). The observed and expected heterozygosities in a total population were 0.748 and 0.769 and ranged from 0.746 to 0.750 and 0.656 to 0.769, respectively. Overall, the results confirmed that the Tazy breed has a high level of genetic diversity, no significant inbreeding, and a specific genetic structure. Three gene pools underlie the genetic diversity of the Tazy breed. SNP analysis using the CanineHD SNP array, which contains more than 170,000 SNP markers, showed that the Tazy breed is distinct from other sighthound breeds and genetically related to ancient eastern sighthound breeds sharing the same branch with the Afghan Hound and the Saluki. The results, together with archeological findings, confirm the ancient origin of the breed. The findings can be used for the conservation and international registration of the Tazy dog breed.

“…Среди наиболее удобных маркеров для проведения генетических исследований являются микросателлиты (STR) [1,2,8]. Данный тип генетических маркеров относится к «нейтральным», поскольку не влияет на проявление фенотипических признаков животных и не подвергается давлению естественного и искусственного отбора [2,3]. Микросателлиты обладают высоким полиморфизмом, что позволяет эффективно их использовать для анализа генетического родства и процессов, происходящих в популяции [4].…”

The aim of the research is to evaluate changes in the allelic structure of DNA microsatellites in a herd of Nenets reindeer. The work was carried out in the Priuralsky district of the Yamalo-Nenets Autonomous Okrug, on an experimental herd of animals belonging to the Yamal experimental station. The allelofund included a microsatellite profile of 300 deer obtained as a result of the 2018 study and 100 animals analyzed in 2022. It was found that significant transformations were observed at all loci, with the exception of NVHRT24. In the microsatellite profile of 2018, there were 6 alleles with a total frequency of 0.298, which were not detected in the 2022 studies. In 2022, 8 alleles with a total frequency of 0.105 not identified in the previous study were established. The Shannon index indicates a slight increase in genetic diversity in the analyzed population (by 0.059), as well as an increase in the observed heterozygosity of animals (by 0.074). The fixation index for all analyzed loci showed that both in the sample of 2018 and 2022, there was a deficit of heterozygotes in the study population, however, the data of 2022 indicate a decrease in the deficit of heterozygotes by 0.089. Analysis of the divergence of the population for individual loci indicates that the maximum divergence of the allelic structure occurred at the RT9 locus (d=0.331), RT30 (d=0.236) and NVHRT76 (d=0.231), and the maximum similarity was preserved for the loci NVHRT24 (d=0.007), RT1 (d=0.0014) and RT7 (d=0.0020). Thus, pronounced gene drift was observed in the studied population.
