[Antisocial behaviour and variations in length of Y chromosome (author's transl)]

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.
