The research was performed on inbred C57B 1/6, CBA, CC57Br/Mw interlinear hybrid of the first generation and rats of the AVGUST and VISTAR lines only month old males subjected to conditions of hypo-, normo- and hyperdynamia for two months. The statistically reliable dependence is shown between mechanical underloadings and overloadings and macro-microscopic changes in the hind limb skeleton of animals under experiment. Genetical determination of growth and formation of the fore-limb skeleton is established. Hereditary susceptibility and the phenomenon of heterosis in the studied characters are preserved under all motor conditions.
