ABSTRACT

The allelic polymorphism and specificity of the allele distribution and their frequencies were studied by microsatellite DNA loci (Psp12, Psp21, Psp26, Psp28) in the three paddlefish stocks. The most polymorphic locus was Psp26, the average number of alleles per locus was 7.6. The presence of common allelic variants in the studied loci indicates the common origins of paddlefish stocks cultivated in Ukrainian fish farms. The presence of different alleles by microsatellite DNA markers indicates the probable effect of the conditions of cultivation and the geographical location of fish farms on the specificity of the alleles distribution.
