Allele Fund Characterization Of Edilbay Sheep By Dna-Markers Polymorphism

Abstract

Due to advanced development of applied scientific research in the field of agriculture, creating methods of genomic selection based on DNA technology determines the relevance of the present research. Studying polymorphic systems of blood proteins of fat-tailed sheep, the authors determined the degree of differentiation of the genetic structure of Edilbay sheep by alleles and their correlation with productive qualities. The analyses revealed that the GH-2 gene influences the synthesis of development hormone and on the whole organism of experimental sheep in indirect ways, including the secretion of insulin-like growth factor IGF-1. Due to their role in regulating cell proliferation and muscle tissue development through the stimulating effect of testosterone, the GH-2 and IGF-1 genes are considered as candidate markers for indicators of sheep meat productivity.
