Boys who have a so-called "warrior gene" are more likely to join gangs and also more likely to be among the most violent members and to use weapons, a new study finds.
"While gangs typically have been regarded as a sociological phenomenon, our investigation shows that variants of a specific MAOA gene, known as a 'low-activity 3-repeat allele,' play a significant role," said biosocial criminologist Kevin M. Beaver of Florida State University.
