In this article the genetic effects on the development of physique are considered. Our main purpose is to determine how genetic factor and environmental factors are interacting to produce human dovelopment. Unfortunately, we have few studies of this sort in our field, but many studies on heredity of mental ability can be seen in psychological field. The interactions of heredity and environment always exist and are understood conceptually, but such conceptual understandings are not so useful or practice of physical education. Thus we attacked this studies. The statistical tools have been used to make this study and many interesting results were found as follows ; 1. As the age advances, the genetic effect grows apparent in stature, but it decreases in weight ; 2. At the stage when boys and girls grow more rapidly, the hereditabiliity appears greater in stature but less in weight; 3. With realization ratio of heredity, heredity of stature tends to be realized about 80% at 15 of age in both sexes, but about 20% to 35% in weight; 4. According to the tetracholic correlation, these children who have greater-statured parents tend to become the greater-statured relatively. This is not sure in weight. The data used to compile this study were not exhaustive enough to make genela-rization of these results, but it is believed that this study produced many useful hypo- thetical theories, and we are going to continue to study these problems which have been raised here.
