Abstract
Goal. To characterize the features of the genetic structure of scaly and frame carps of the Antoninskyi-Zozulenetskyi intrabreed type according to protein and enzyme systems. Methods. Laboratory studies, computer statistical analysis. Results. The genetic structure of the Antoninskyi-Zozulenetskyi intrabreed type of scaly and frame carp was studied by protein markers. Species-specific features of the genetic structure of the studied loci were revealed. The level of available and expected heterosis readiness was calculated. It was established that the increased allelic and genotypic diversity of the genetic structure can be caused by a slightly increased intensity of the selection work. The detected excess of heterozygotes at individual loci indicated the presence of stabilization processes of the genetic structure. Conclusions. Breed-specific features of the genetic structure of the Antoninskyi-Zozulenetskyi intrabreed type of scaly and frame carp breeds were revealed. A certain genetic differentiation was observed for individual protein markers, as well as a predominance of the actual level of average heterozygosity for all loci over the expected one. It was established that the TF, ALB, and EST loci belonged to polymorphic systems, and the SR, AMI, PN, and HB loci belonged to monomorphic systems.
