FEATURES OF GENETIC MONITORING IN RABBIT BREEDING BY DNA MARKERS

Abstract

Molecular markers based on DNA polymorphism are increasingly used in the study and preservation of the farm animals genetic diversity, particularly in rabbits, the identification of individuals, phylogenetics, the mapping of useful traits and resistance to stress factors, in the selection process, biotechnology. The combination of methods of classical selection of rabbits with DNA analysis of the original forms and hybrid populations is a promising direction of research related to the intensification of the process of creating genotypes with given parameters of valuable, selectionally significant traits. Therefore, using of DNA markers as a modern genetic method and is an important addition to traditional breeding in animal husbandry, namely in the rabbit breeding.

According to the results of our own and other studies published by other authors considered some topical issues of the use of molecular genetic markers in the selection of farm animals, mainly rabbits. Possible promising approaches to assessing the selective value of integrated genotypes of animals using the complex of genetic systems of marker genes and optimization of parameters of population gene pools are discussed.

The influence of the genetic loci of rabbits in the formation of quantitative traits of animals is noted. The importance of the introduction and use of genomic selection for the early prediction of fetal rabbits and finding high-value animal genotypes is substantiated.

The main classification of DNA markers, which are used in molecular genetic certification of rabbits, is submitted. The directions of increasing their efficiency are discussed, in particular, by identifying DNA markers, the polymorphism of which is directly associated with the variability of economically valuable traits. The methodology is used to label various breeds of rabbits for RFLP, ISSR and microsatellite DNA markers. Genomic testing data (DNA certification) in the preservation of the gene pool of agricultural species of animals, as well as the using of molecular genetic research n the of in the system of biodiversity conservation.
