Quantitative and Qualitative Study of Acrocentric Associations in 109 Normal Subjects
Authors

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.
