Using 12 STR- markers (MCM042, INRA006, MCM527, ETH152, CSRD247, OARFCB20, INRA172, INRA063, MAF065, MAF214, INRA005, INRA023), the population genetic structure of Askania Karakul sheep of the Ivanov research institute of livestock husbandry and plant growing of steppe regions Askania- Nova, was studied. A total of 66 animals were genotyped. According to the results of microsatellite analysis of Askania Karakul sheep, it was established that the population under consideration is characterized by the absence of inbreeding F = − 0.006 , polymorphism indices P = 76.26% and a sufficiently high level of genetic diversity H = 0.726 . The revealed intrapopulation genetic heterogeneity of Askania Karakul sheep, expressed in segmentation on embryonic clusters, is the progress of the conducted interline crossings. The obtained results can be used in the development of selection and breeding programs for breeding Askania Karakul sheep.
