Genetic characteristics of cattle breeds in Western Siberia using STR markers

Submitted by Гость (not verified) on Thu, 11/06/2025 - 21:08

The use of microsatellite analysis for parentage verification has enabled the creation of an extensive information base of genetic markers for cattle, which can be successfully used to control breeding processes in breeds and individual herds. The aim of our research was to study the genetic diversity of seven breeds of dairy and beef cattle, their phylogenetic relationships, interbreed and intrabreed differentiation, genetic diversity, homo- and heterozygosity, inbreeding, and other populationgenetic parameters.

The purpose of the study is to analyze the genotypic structure and population-genetic parameters of the West Siberian meat and Kulunda fine-wool breed of sheep by the CAST, GDF9 and KRT1.2 genes and blood groups. Molecularnogenetic and immunogenetic studies were carried out in the SRIAH (Siberian Research Institute of Animal Husbandry SFSCA RAS) biotechnology laboratory. PCR-RFLP analysis to determine genotypes was performed according to the described and approved methods on a C1000 “BioRad” amplifier; the results were visualized using an E-Box-CX5.TS-20.M gel documentation system.
