Chromosome studies on 129 tall men surveyed in four different institutions for the care of criminal males in Pennsylvaniia showed that 1 in 11 subjects displayed aneuploidy of the sex chromosomes; specifically, five cases of 47,XYY and seven cases of Klinefelter syndrome were identified. All the aneuploid subjects were mentally ill; none had been cytogenetically diagnosed.

It is not yet known whether an XYY genotype results in a characteristic phenotype, so a genetic study of a normal population and a prospective study of newborns with various genotypes are needed which would create complex research and ethical problems.
A study of the XYY syndrome in tall men and juvenile delinquents.
Four new examples of the XYY karyotype were ascertained in a survey of selected male populations, and all came from broken or unsatisfactory homes, perhaps an important factor in leading to their sociopathic behavior.
XYY Survey in an Institution for Sex Offenders and the Mentally III
Survey of 200 tall anti-social men at Atascadero State Hospital in California were studied in order to obtain additional information on the incidence of sex chromosome aneuploids.

The XYY syndrome.
Chromosome aberrations in 2159 consecutive newborn babies.
It is suggested that D/D translocation heterozygosis will be found in random human populations with a rate of at least 1 in 1000 and probably represents the most frequent type of chromosomal rearrangement.
X chromosome errors in female criminals.
To the Editor:— Since W. M. Court Brown first raised the broad question of whether individuals with abnormal sex-chromosome complements "could be held in law to suffer from diminished responsibility," much attention has been accorded the legal status of criminal XXY and XYY males.
The XYY Anomaly
Most of the subjects were mentally retarded but so were the controls, and certain abnormalities were found in their electrocardiograms and in their Psychological test results, notably in the direc­ tion of introversion and decreased self-esteem.
Psychological and Sociological Investigation of XYY Prisoners
A survey of tall prisoners at a London prison, with a population which, although heterogeneous, is largely composed of recidivists from London and the Home Counties, suggests that males with the sex chromosome constitution XYY tend to be concentrated among tail detained delinquents, especially those with psychiatric disorder.


Psychopathy, Mental Deficiency, Aggressiveness and the XYY Syndrome
Preliminary findings are reported from a survey in a comparable population in the United States of mentally sub-normal male patients with “dangerous, violent or criminal propensities” found that seven of 197 inmates had an XYY sex chromosome constitution.
Aggressive Behaviour, Mental Sub-normality and the XYY Male
The purpose of this communication is to report the findings in a survey of mentally sub-normal male patients with dangerous, violent or criminal propensities in an institution where they are treated under conditions of special security.
