They are 10 remains, 8 out of 10 had brown skin, dark eyes, and dark hair. 2 out of 10 had grey-blue eyes, these two had one blond and the other dark hair.

Eight out of 10 individuals had brown eyes, dark hair (to varying degrees), and a predominantly dark skin during their lifetime. Individuals from two burials had gray-blue eyes, and one individual had blond hair. The most probable AB0 blood group was identified in eight people, of which five blood group 0 (I) group, four had blood group A (II), and one had blood group B (III). The allele frequency distribution was assessed for ten population-specific autosomal markers and suggested high heterogeneity for the ethnogeographic origin of the Khazars examined. The results are evidence for ethnocultural, genetic, and phenotypic diversity of the Khazar Khaganate.
