The Genetics of Violence

Introduction
     We, in the 1990’s, are slowly and inevitably being faced with the sociological and biological implications of impending genetic power. This power is analytical, in such cases as the Human Genome Project, which will hopefully succeed in mapping out the genetic code for the entire human genetic composition.
Moreover, this power is preventative and participatory in that it can be, and is being, used to control the behavior of humans and other animals. This new power, in the eyes of many, is as risky and potentially hazardous as atomic energy: it must be treated carefully, used under close supervision, performed under professional consent and observation, otherwise, people

Additionally, the known IQ’s of the men were typically around 85. The history of this sort of behavior was found to be typical, as nine other males in the family, tracing back to 1870, had the same type of disorder. It became evident that there was something wrong in the lineage of the family. Hans Brunner, a geneticist at the
University Hospital, has been studying the family since 1988.
     It was discovered that the men had a defect on the X chromosome that helps regulate aggressive behavior. Brunner was cued to the fact that the defect was on the X chromosome because the trait was passed on from mother to son, and none of the women, with two X chromosomes, were afflicted. The gene normally codes for the production of the enzyme monoamine oxidase A (MAOA), which breaks down three important neurotransmitters that trigger or inhibit the transmission of nerve impulses. One of these neurotransmitters is norepinephrine, which raises blood pressure and increases alertness as part of the body’s "fight or flight" mechanism. Brunner believes that the lack of this neurotransmitter could cause
