Question 7

Alien^3 takes place at a penal colony on Fiorina "Fury" 161. Most of the prisoners who live at this penal colony (described by the superintendent as murderers, rapists, and child molesters) share a particular genetic disorder. This genetic condition was, in the 1960s, falsely linked to being more prevalent among some populations of criminals. What is this genetic condition?

Double-Y Chromosome (XYY Syndrome)
