Determination of cattle breed and assignment of individual animals to that or another group based on distinctions of genotype is of great importance in genetics and selection. Using of PCR-analysis opened new possibilities for typing DNA. The procedure of PCR was optimized for animal DNA. Two methods of PCR, RAPD and SSRP, were applied for investigation of molecular-genetical polymorphism in three cattle breeds (Ukrainian red-motley lactescent, Golshtine and Simmental). A dendrogram reflecting genetical mutual relations between analyzed animals was drawn. The level of homo-heterozygosity and the distribution of microsatellite alleles were determined. System for investigation of molecular-genetical polymorphism in the cattle breeds and characterization of genotype of individual animals were developed and tested on a real population.
