The Comparative Analysis of the Allele Pool of Thoroughbred Horses in Different Countries

The aim of the present study was the conducting of comparative analysis of allele pool of Ukrainian population of Thoroughbred horses and the populations from England, USA, Russia and South Korea using microsatellite loci of DNA on the basis of our own researches and literary sources. Comparative analysis of allele pool of Thoroughbred populations from different countries was conducted using 6 microsatellites loci: AHT04, AHT05, HMS03, HMS06, HMS07 and HTG04, which are recommended by International Society for Animals Genetics (ISAG) for parentage verification and identity testing of horses. The number of observed alleles in Ukrainian population was higher than in other countries. The most similar populations by allele frequencies were English and American populations of Thoroughbred horses.
