Abstract. This study investigates the genetic diversity of the Evenskaya breed of domestic reindeer using microsatellite DNA markers. The research was conducted on reindeer bred in the APC (F) “Tompo” of the Tomponsky district of the Sakha Republic (Yakutia). The article presents the allele frequencies of 16 microsatellite markers in Evenskaya reindeer, providing valuable data for future research, including comparisons of allele frequencies and genetic diversity indices with other reindeer populations (e.g., from different regions or breeds). The study confirmed the high genetic diversity of the Evenskaya breed. A minimal difference was observed between expected and observed heterozygosity, indicating the absence of significant inbreeding within the studied population. Furthermore, the article compares the genetic diversity of Evenskaya reindeer from the Tomponsky and Oymyakonsky districts of Yakutia. The comparison of allele frequencies revealed notable differences between the populations, particularly in the loci Rt6, BMS1788, Rt30, Rt7, FCB193, and C276.  The Tomponsky population exhibited 13 alleles that absent in the Oymyakonsky population, with most occurring at low frequencies except for allele 144 bp in the FCB193 locus.  Both Nei's genetic distance (0.086) and Fst analysis (0.017) indicated a relatively small genetic differentiation between the populations.
