Answer:
True
Explanation:
In a study about violent people, it was found that all the violent subjects carried a version of the low-activity MAOA gene, which previous research had considered to be the "gene of violence" since it is constantly linked to aggressive behavior. A deficiency of the enzyme that this gene controls could result in "dopamine hyperactivity", especially when a person drinks alcohol or uses drugs like amphetamine. Although this all is true, most people with that characteristic will never commit a violent act.
