The stereotyped break with gap of a chromosomal variant is rarely observed. This anomaly is transmitted according to autosomal dominant rule. The distal part of the broken chromosome may either be still bound to the sister chromatid through mitotic non-disjunction, forming a triradial figure, or take a moniliform and pulverized appearance, evoking premature chromosome condensation.

The length of they chromosome has been measured for 50 male criminals in a psychiatric security hospital and for 50 non criminal control men. The distribution was normal for the 2 populations and there was no significant difference between the mean Y/F, Yf/Y values and the number of brightly fluorescent segments. For criminal psychopaths, there was no close correlation between the size of the Y chromosome and the psychiatric or criminal background.
