Abstract
The problem whether or not there is any relationship between heredity and environment was presented in many works [1, 2, 3, 4, 5]. It is important to find not only theoretical solution to that problem as nowadays this notion is widely used in analysis of sports achievements, efficient stimulation of morphofunctional and motor development of children and adolescents through organized forms of sports activities. Results of research al-low to determine adjustment abilities of an individual, they help to prepare the line of coaching and also suggest desirable adjustment changes in professional life and physical education.This presentation concentrates on assessment of the strength of genetic conditioning of basic somatic and same aspects of strenght. 205 full families ( mother, father, and a child ) were investigated. Measurements of height, LBM, flexibility static and explosive strenght were taken. On the base of same aspects of strenght total strenght and Maximal Anaerobic Work were calculated. The strength of genetic control for particular features was established by means of classical methods of genetics of quantity traits and on the basis of resemblance between parents and children. That led to the following calculations:- intra-family rates of correlation (7-10, 11-14, 15-19 age groups)- rate of correlation between parents as the measure of assortative maltting.- on the basis of corrected rates of correlation ( corrected in case of possible influence of assortative maltting ) heredity rate was calculated h2 = 2 Csk.The analysis of achieved results led to the following conclusions:1. It was noticed that the most resemblance between children and their parents as for body height, flexibility and LBM are concerned.2. Full genetic control appeared only in the situation where developmental possibilities were used ( age group 15-19).
