Reproductive qualities in pigs of the Ukrainian steppe white breed in connection with structural organization of their gene pool for complex of loci

The author have investigated the reproduction qualities in pigs of the Ukrainian Steppe White breed having different combinations of nonallelic genes on closed genetic systems of blood groups (B, D, E, F, G), transferring (Tf) and amylase (Am). The study of population-genetic parameters in pig herd permit to revealed the optimum level of genetic variability and peculiarities of selection action on animals with different genotypes using polymorphous systems of blood groups and serum proteins.
