Prison survey for the XYY karyotype in tall inmates

摘要

Cytogenetic analysis of tall Alabama prisoners showed two of 100 Caucasian and none of 108 Negroes to have the XYY karyotype. Convictions were numerous for each XYY prisoner, with robbery, burglary, and automobile theft being the most common offenses. Psychological evaluation indicated IQs of 105 and 108.
