The MAOA gene is related to aggression and criminal behavior, and individuals with the low-MAOA gene are more likely to exhibit these traits. Since Marcus carries the low-MAOA gene, he is at greater risk for aggression and criminal behavior in adulthood than J.J., who carries the high-MAOA gene. However, it is important to note that genetics is only one factor in the development of aggression and criminal behavior and does not determine an individual's destiny.
