The relationship between variability of the heterochromatic regions of chromosomes 1, 9, 16, and Y, and anthropometric characteristics (length and mass of body, shoulder diameter) in 70 children with embryopathies of unknown etiology and in 40 children with Down syndrome was studied. The positive statistically significant correlations of the C segment lengths of chromosomes 1, 9, 16, their sum included, and the above characteristics were found. The correlation coefficients of Y chromosome were not significant. The questions of the functional role of the structural heterochromatin and its influence on the viability and physical development of the organism are discussed.
研究了70名病因不明的胚胎病患儿和40名唐氏综合征患儿中1号、9号、16号染色体以及Y染色体异染色质区域的变异性与人体测量特征（身长、体重、肩径）之间的关系。发现1号、9号、16号染色体的C段长度及其总和与上述特征存在统计学上的显著正相关。Y染色体的相关系数不显著。文中讨论了结构异染色质的功能作用及其对机体生存能力和身体发育的影响问题。
