[Genetico-demographic approach in anthropological studies. III. The use of family names in the study of Khakass populations].

Monofilety is a typical characteristic of most Khakass surnames. A special pool of surnames is historically associated with each of the ethnographic groups that allows to use them as a reliable ethnic determinant. The combination of matrimonial surnames does not occur by chance in the populations investigated. A significant mate assortativeness can be revealed due to the fact that people deliberately escape marital isonymy. If surnames are considered as selective neutral locus alleles, their distribution in the population can be compared to that of the genetic markers and used as an indirect method for the description of the genetic structure in the population.
