The Crime Gene

clipped from news.yahoo.com WASHINGTON (Reuters) - Three genes may play a strong role in determining why some young men raised in rough neighborhoods or deprived families become violent criminals, while others do not, U.S. researchers reported on Monday. People with a particular variation of the MAOA gene called 2R were very prone to criminal and delinquent behavior, said sociology professor Guang Guo, who led the study. "I don't want to say it is a crime gene, but 1 percent of people have it and scored very high in violence and delinquency," Guo said in a telephone interview.
