Outline of Final Research Achievements

Kazakhstan native horse has been expected to retain the genetic influences of ancestral wiled horse. In the present study, therefore, we investigated the genetic characteristics of the native horse population of Kazakhstan. We determined haplotypes of mitochondrial DNA and Y chromosome, as well as genotypes of several functional genes associated with particular traits of horse in 106 Kazakhstan native horses. The results of mitochondrial DNA haplotypes indicated that the population retains high level genetic diversity and unique genetic features in maternal lineage. On the other hand, the results of Y chromosomal haplotypes indicated relation with the common European breeds in paternal lineage. The genotypes of genes associated with gait, physical performance, and withers height suggested that the population has not been under strong selective pressure on these traits.
