[An association between human morphological phenotypical characteristics and the activity of chromosomal nucleolar organizer regions in the interphase cell nucleus in the population of indigenous people of Kursk region].

During the survey of 215 indigenous inhabitants of Kursk region, the activity of chromosomal nucleolar organizing regions (NOR) was examined in peripheral blood lymphocytes by a visual semiquantitative method based on silver salt impregnation (Howell W. M., 1975), and the general anthropometric indexes were determined. Significant differences in anthropometric indexes were identified among the groups with high, medium and low values of 10Ag NOR. It was established that with the increase of 10Ag NOR value in men, body mass and body mass index, waist girth and hip girth, waist-to-hip ratio and width of shoulders increased, while in women there was an increase in body mass, height, body mass index, hip girth and length of the legs.
