DNA marking of the rate of maturation of gonads in female sterlet x beluga (A. ruthenus x H. huso) hybrid under conditions of recirculation systems
Abstract To create a theoretical basis for the development of new technologies for the formation of highly productive sturgeon herds, work has begun on conducting research on DNA - markers associated with economically useful traits. At the first stage of the work, polymorphic regions of the mitochon...
