the warrior gene
A variant of an MAOA gene, known as a ‘low-activity 3-repeat allele, has been shown to have a relationship to violence in males.
“Previous research has linked low-activity MAOA variants to a wide range of antisocial, even violent, behavior, but our study confirms that these variants can predict gang membership,” says Beaver, the Florida State researcher. “Moreover, we found that variants of this gene could distinguish gang members who were markedly more likely to behave violently and use weapons from members who were less likely to do either.”
