STR-genotyping of sturgeon fish grown in the RAS: significance and prospects of application

The article presents the results of studies on the assessment of polymorphism in 7 microsatellite DNA loci of sturgeon fish, in which 69 alleles were identified. All the studied individuals were heterozygous, respectively, the level of observed heterozygosity was 1. Based on the results of the evaluation of STR-loci polymorphism in Siberian sturgeons grown in the RAS, it was found that in the study group, the ratio of expected and observed heterozygosity, as well as the index of fixation (Fis), indicates an excess of heterozygotes in them and a high "reserve" of genetic diversity in STR-loci.
