Our work was aimed at the evaluation of genetic diversity of three domestic equine breeds which differ bythe history of their formation and use. Methods. Genotyping of DNA samples of three breeds of horses, namely,Hucul (78 animals), Thoroughbred (51 animals) and Ukrainian Saddle Horse (152 animals), was conducted by 11microsatellite loci, recommended by the International Stud Book Committee (ISBC) and the International Society forAnimal Genetics (ISAG). The mathematical analysis involved parametric and non-parametric methods of statistics.Results. The results of polymorphism analysis of the gene funds for Hucul, Thoroughbred and Ukrainian Saddle horsesby 11 microsatellite DNA loci were fi rst presented in Ukraine. It was demonstrated that the study of microsatelliteDNA loci allows both determining the reliability of origin of pedigree animals and controlling population processes indifferent breeds and the polymorphy of the very breeds. Conclusions. The molecular and genetic analysis of equinebreeds, differing by their provenance, demonstrated specifi cities of genetic structure of each breed, which correspondto the formation history of their gene funds. The populational-genetic analysis using different mathematical methodsis recommended for the purposes of evaluating and forecasting microevolution processes, controlling gene fundformation both during the breeding work and within the system of preserving genetic biodiversity ER -
