Comparative analysis of informativeness of erythrocytes antigenes and DNA-microsatellites as genetic markers in breeding-pedigree work with pigs of Canadian selection

The authors have compared the informativeness of two systems of analysis of genetic polymorphism - erythrocytes antigens (EA) and DNA-microsatellites (DNA-MS) for characteristic of genealogical structure pig's herds of the Yorkshire, Landrace and Durock of Canadian selection. The differences in degree of heterozygosis in studied groups in connection with used analysis system were shown. The reliable correlations were revealed between degree of heterozygosis of parents calculated with use of EA and DNA-MS and productivity determinants, the character of correlations depends on breed of animals.
