Linear measurement of blocks of constitutive heterochromatin and the euchromatin portion 1q-h in three members of a family was used to study the dependence of the size of C blocks on the degree of chromosomal contraction. The results demonstrate that the size of heterochromatin portions decrease regularly with an increases of the degree of euchromatin contraction. The dependence was found to be linear, except for mitoses with an extremely high or low degree of contraction. The finding was used for the development of a new method of evaluation of constitutive heterochromatin.
对一个家族的三名成员的组成型异染色质块和常染色质部分1q-h进行线性测量，以研究C块大小对染色体收缩程度的依赖性。结果表明，随着常染色质收缩程度的增加，异染色质部分的大小有规律地减小。除收缩程度极高或极低的有丝分裂外，这种依赖性呈线性。这一发现被用于开发一种评估组成型异染色质的新方法。
