Abstract
By four meristic and 14 morphometric characters of the skull the phenetic relationships of Altai Osmans of the genus Oreoleuciscus from lakes Ust-Nur (the Selenga Basin), Sangiyn-Dalai-Nur (the Khangai Highland), and Orog-Nur (Lake Valley) are estimated. Principal components analysis is performed. No interpopulational differences by the set of meristic characters are found. By the set of morphometric characters the specimens from Lake Ust-Nur in the space of principal components are separated from specimens from two other lakes while the distributions of specimens from Lake Sangiyn-Dalai-Nur and Orog-Nur overlap. With consideration of estimates of similarity in the structure of interpopulational differences it is assumed that separation of the phyletic line common for populations of lakes Ust-Nur and Orog-Nur from the phyletic line of population of Lake Sangiyn-Dalai-Nur preceded separation of phyletic lines of populations from lakes Ust-Nur and Orog-Nur.
