[The components of the phenotypic dispersion of the basic typological traits and of work capacity in horses of the Ukrainian saddle breed]. The indexes of standardized deviations by the measured characters (probits) are expedient to be used for distribution of horses according to classes M-, M0 and M+, under these conditions one can select individuals M0 for to rise their capacity for work and expressivity of the type of breed.
[The intraspecific differentiation of Przhewalski’s horse and the domestic horse by 5 molecular genetic markers]. Analysis of albumin, transferrin, receptor to vitamin D, esterase, alpha 1-beta glycoprotein polymorphisms in Przhewalski's horse, Orlov's and Russian trotters, Guzul and Yakutian domestic horse breeds was carried out. The data about similarity of intraspecies differentiation of Przewalski's horse's populations and interbreed distinctions were obtained. Locus-specific particularities of genetic structures of investigated animal groups were revealed.
[The variability and heritability of the indices of speed and exterior characters in horses of the Orlov trotter breed]. Study of the variability and heritability of sprightliness and exterior characteristics which are the constituent factors of capacity for work of trotting horse breed, permits predicting and planning the direction of selection work in the breed, and determining the efficiency of animals selection according to phenotype. To increase the level of capacity for work of Orloff trotting horse breed, according to the paper data, more consideration should be given to correctness of the exterior, as a biomechanical basis of the horse motion.
[Genetic structure of the Orlov trotter and the Russian trotter]. The genetic structures of Orlov's and Russian trotters for 16 biochemical systems have been comparatively analyzed. Polymorphism of 6 systems of these horse groups is revealed. The main genetic differentiation between Orlov's and Russian trotters is observed on the transferrin and phosphoglucomutase loci.
[Effect of selection on heterozygosity of farm animals]. A stabilizing selection which is made in cattle according to phenotypic characters affects simultaneously a genetic character--the level of individual heterozygosity++. As a result animals with mean (modal) level of heterozygosity++ have the least probability of elimination. Similarly, the driving selection in pigs and horses leads to a change in both phenotypic characters and genetic character, the level of individual heterozygosity++. In this case the most heterozygous animals have the least probability of elimination.
