[Genetic and ecologic factors of the variability of growth and development rates in postnatal human ontogeny]

The contribution of genetic and ecological (high-altitude, urban-rural) factors into variability of the level of somatic development in different stages of pubertal development (7-17 years) of the male ontogeny was studied. It was found, that realization of genetic potential of growth and development in children and adolescents is not substantially influenced by high-altitude locations, but by ecological differences between urban and rural communities, induced by socioeconomic conditions.
