Ідентифікація алельних варіантів мікросателітної ДНК веслоноса (Polyodon Spathula)

The microsatellite DNA assay of paddlefish (Polyodon spathula) and the genetic polymorphism of the investigated group of fish (n = 38) were performed in this paper for the following DNA-markers: Psp12, Psp21, Psp26 and Psp28. According to the microsatellite analysis, 24 allelic variants were identified for all loci. The Psp26 and Psp28 loci were the most polymorphic (7 allelic variants), and the Psp21 locus was the least polymorphic (4 allelic variants). For the Psp12 loci two new allelic variants of 214 bp (5,26%) and 216 bp (34,21%) were identified, and for the Psp26 loci one new allelic variant 164 bp (7,90 %) was identified. According to population calculations, it was found that in this group of fish predominates individuals with heterozygous genotypes and a fairly high level of genetic variability is observed.
