[Frequency criterion of choice of surname for the study of the genetic structure of the population].

On the example of 7 populations of the regional level allowability of using surnames with frequencies exceeding 0.001 in adequate estimation of the population structure indices is shown. The correlation coefficient between genetical distances calculated with the help of all surnames in the list, and those estimated using only frequent surnames was more than 0.9 in all populations studied, values of the correlation coefficient analogous to the FST statistics of Wright being 0.76 to 0.97.
