This study involving 109 normal subjects shows that the mean number of associations by cell seems to represent a biological constant which is not sex related and increases with age, especially after 33 years. From a qualitative point of view, the associations are not at random and their distribution varies from one individual to another. The tendency to associate is a characteristic of a given chromosome in a given individual.
这项涉及109名正常受试者的研究表明,细胞的平均关联数似乎代表了一个与性别无关且随年龄增长而增加的生物学常数,尤其是在33岁之后。从定性的角度来看,这些关联并非随机的,其分布因人而异。关联的倾向是特定个体中特定染色体的一个特征。
