Monoamine Oxidase A gene is responsible for the production of monoamine oxidase enzymes that helps in the breakdown of neurotransmitters serotonin and dopamine, which affects a person's mood. Studies have shown that having a low-activity form of MAOA gene greatly affects a person's behavior making him more aggressive, thus earning its title of warrior gene.

Warrior gene is present on the X- chromosome, with this, it was said that it puts men at greater risk because of inheriting only one copy of the chromosome. It is believed that inheriting this form of gene together with an adverse environment increase the possibility for violent behaviors. Men with warrior gene are not necessarily aggressive in nature but rather respond more aggressively in certain occasions.

Being a novel topic as it is, the warrior gene gave rise to new heights through raising it as a form of defense under the penal law. Today, it is being examined to help mitigaze crimes in cases wherein the accused carries the said gene to provide equality and justice in the face of the law.
