[Interaction of polymorphic systems in a population of Semirechenskaya swine breed].

Associations between the alleles of nonlinked polymorphic genetic systems were studied in the population of the Semirechenskaya breed of pigs. The study of marker pairs of 21 genetic systems revealed that 7% of associations are statistically significant. Most of the associations detected are assumed to arise from breeding by commercial productivity traits and from the formation of an integral genotype adapted to conditions of artificial selection in the population.
