The investigation has been performed in mono- and dizygotic twins of the Ukrainian ethnic and territorial groups. As a whole 196 pairs of twins, among them 80 pairs of mono- and 116 pairs of dizygotes of both sex at the age of 12-60 years have been undergone the examination. The twins selected are divided into two age groups--period of sex maturation (12-17 years of age) and that of maturity (30-60 years of age). Quantitative parameters on composition of the components of the upper extremity mass (fatty, muscular and osseous) are studied in all the twins. Coefficients of intrapaired correlation and indices of Holzinger's heritability are calculated according to an original program, using the microcomputer "Electronika B3-34". The degree of hereditary and environmental influences for development and formation of the main components of the upper extremity mass at certain stages of individual development are characterized with ontogenic changeability. With age the degree of hereditary dependence of the development and formation of the upper extremity mass components decreases, and sex dimorphism according to the degree of the hereditary dependence of the components studied is displayed as a greater hereditary determination in male persons.
该研究在乌克兰不同民族和地域群体的单卵双胞胎和双卵双胞胎中进行。总共对196对双胞胎进行了检查，其中包括80对单卵双胞胎和116对双卵双胞胎，年龄在12至60岁之间，涵盖了两性。所选双胞胎分为两个年龄组——性成熟阶段（12至17岁）和成熟阶段（30至60岁）。对所有双胞胎的上肢质量组成部分（脂肪、肌肉和骨骼）的定量参数进行了研究。使用“Electronika B3 - 34”微型计算机，根据一个原始程序计算了配对内相关系数和霍尔津格遗传率指数。在个体发育的特定阶段，上肢质量主要组成部分的发育和形成受遗传和环境影响的程度具有个体发育变异性特征。随着年龄增长，上肢质量组成部分发育和形成的遗传依赖性程度降低，并且在所研究组成部分的遗传依赖性程度方面，性别二态性表现为男性具有更大的遗传决定性。
