Abstract

Modern tendencies to intensification of breeding of domestic farm animals, including reindeer, necessitate a detailed study of genetic variability in candidate genes associated with meat productivity. At present, the primary task is to search for molecular genetic markers for identification and selection of individuals with desired characteristics. One such potential candidate gene is the DQA1 gene. It is hypothesized that individual genes of the immune system may influence the growth performance of animals. Variability in the DQA1 gene region has been associated with cattle size and beef production in many studies. Principal component analysis on DQA1 variability united wild and domestic reindeer in Yakutia, which implies gene flow between local breeds of domesticated reindeer and wild populations and the formation of similar adaptation mechanisms. However, significant differences were found between wild and Evenki reindeer of Amur oblast, which may reflect the influence of domestication processes on the Evenki breed.
