...much power do genes hold over behavior? Can they predict, for example, whether a child will grow up to join a gang? Those are among the questions raised by a new Florida State University (FSU) study released June 5. (What Can Genetic Tests Tell...
...latest research, however, takes the association one step further. It is the first to link low activity on the MAO-A allele in young men both to an increased likelihood of joining a gang and to a greater tendency to use weapons and violence. "For the first time, we were able to establish a direct connection between the MAO-A gene and the choosing of a violent lifestyle," says Kevin Beaver, a biosocial criminologist at FSU and lead author of the study published in Comprehensive Psychiatry...
...most comprehensive survey of health-related behavior among adolescents between 7th and 12th grade, which started in 1994. Slightly more than half of the study's male participants had low-level activity on the MAO-A gene, and about 3% of the total pool reported having joined a named gang in the past year.

Beaver and his colleagues found that those males carrying the low-active MAO-A gene were nearly twice as likely to join an organized gang than males with the high-active gene, and when in a fight, they were nearly twice as likely to brandish a weapon. Of the gang members studied, those who had a low-activity MAO-A allele were more than four times more likely to use a weapon when compared with male gang members who carried a high-activity version of the allele. "At the very least this suggests a genetic risk factor that can help...
