We chose the calpastatin and androgen receptor genes as such genes to study. Polymorphisms and indels in the androgen receptor gene have been associated with height and weight characteristics in different domesticated animal species. Variation in the region of the calpastatin <italic>CAST</italic> gene, according to the results of many studies, has been associated with meat quality and meat productivity of livestock. Principal component analysis of <italic>CAST</italic> variability has grouped together wild and domestic deer from Yakutia, as well as wild and domestic deer from the Amur region, which implies gene flow between local breeds of domesticated deer and wild populations. Moreover, in the case of three microsatellite loci found in this study in the intron of the androgen receptor, principal component analysis separated wild and domestic deer.</p></abstract><trans-abstract xml:lang="ru"><p>Маркерная селекция для повышения мясной продуктивности северного оленя находится в начальной стадии разработки, для которой требуется изучение изменчивости в генах-кандидатах мясной продуктивности. В качестве таких генов нами были выбраны гены кальпастатина и андрогенового рецептора для изучения их изменчивости у северного оленя. Полиморфизм и индели в гене андрогенового рецептора связывают с характеристиками роста и веса у разных видов одомашненных животных. Изменчивость в регионе гена кальпастатина <italic>CAST</italic> по результатам многих исследований была ассоциирована с качеством мяса и мясной продуктивностью скота. Анализ главных компонент по изменчивости <italic>CAST</italic> объединил диких и домашних оленей Якутии, а также диких и домашних оленей из Амурской обл., что подразумевает поток генов между локальными породами одомашненного оленя и дикими популяциями. При этом в случае обнаруженных в данном исследовании трех микросателлитных локусов в интроне андрогенового рецептора анализ главных компонент разделил диких и домашних оленей.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Rangifer tarandus</kwd><kwd>meat quality markers</kwd><kwd>calpastatin</kwd><kwd>androgen receptor</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Rangifer tarandus</kwd><kwd>гены продуктивности</kwd><kwd>кальпастатин</kwd><kwd>андрогеновый рецептор</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд (проект)</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation (project)</institution></institution-wrap></funding-source><award-id>22-16-00062</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Trakooljul N.
