Description
Summary:The article highlighted the problem of genetic defect of Aberdeen Angus cattle. Previous investigation showed the presence in Russian population of Aberdeen Angus cattle of animals carrying in their genotypes the mutant alleles associated with Arthrogriposis multiplex, Developmental Duplication and Osteopetrosis. In some populations, the frequencies of the animals-genetic defects carriers were sufficiently high. The aim of the study was to evaluate the risk of spread of the mutant alleles causing the genetic disorders by their transfer from parents to offspring under absence of control over the genetic defects in the farm, breeding Aberdeen Angus cattle. The analysis has shown increasing of the frequency of animals-Arthrogriposis multiplex carriers about on 10.3% in the population of heifers comparing with population of their mothers and the raising of the mutant allele frequency in six times in F2 generation.
