title: [Possible causes and consequences of the spread of individual allelic variants of the BoLA-DRB3 locus in groups of Holstein and Ayrshire cattle].
abstract: The frequencies of polymorphic variants of the BoLA-DRB3 locus have been estimated in groups of Holstein and Ayrshire bull sires. Considerably increased frequencies of individual alleles have been found in some groups of cattle, depending on the breed and breeding value. The possible causes and consequences of the observed relationships have been analyzed.
