[The intergroup variability of the indices of asymmetry of the human facial skull].

All bilateral sizes of the facial skeleton of Tajik, Khakass and Kazakh skulls have demonstrated an asymmetry. In the three series the greatest values of the asymmetry were obtained for the sizes of the orbital, zygomatic and mandibular areas, the least ones--for the sizes of the upper jaw. Greater sizes were less asymmetrical. The indices of asymmetry of the least sizes of the facial skeleton are characterized by the greatest variability at the intra-group level. The Tajik skulls were considerably different in the degree of asymmetry from both the Khakass and kazakh skulls mainly in the sizes of the upper part of the facial skull. Values of asymmetry of Kazakh and Khakass skulls were similar as a whole.
