Molecular-genetic monitoring in system of preservation of genetic resources of animals

Abstract

The purpose. To develop theoretical approaches concerning expediency of application of modern molecular-genetic methods of probes within the limits of holding genetic monitoring in system of preservation of genetic resources of animals. Methods. Dialectic method of scientific knowledge, analysis and systemic generalization. Results. It is necessary to consider ndigenous breeds as carrying agents of the unique genetic information which cannot be replicated by modern methods of selection. In some ecosystems economically expediently their growing in purity, and also straight introduction in zones where reproduction of highly productive forms is impossible. From this point of view, study of gene pools of indigenous breeds is important for searching new useful genes of quantitative or other attributes (productivity, resistance to diseases and stresses) which in the further can be used in selection. Conclusions. For comprehensive analysis of genetic structure of pedigree resources of breeds development and systematization of methods on determination of the most informative tests for different types of DNA-markers is necessary. Heading of elements of molecular-genetic monitoring will promote detection of carrying agents of valuable genes complexes by deriving molecular-genetic information of features of genetic structure. That will allow identifying and determining optimum content of gene pools and quality of genetic material for backfilling and keeping specimens of biomaterial.
