Is there a gene for aggression

Adoption studies can also help to separate out the effects of genes and environment.40 genes associated with aggression identified.Although we have learned much from these prior studies, future studies should improve the measurement of aggression by using a systematic method of measurement.This enzyme is responsible for the breakdown of three important neurotransmitters.In humans, abnormal aggression is a hallmark of neuropsychiatric disorders and can be elicited by environmental factors acting on an underlying genetic susceptibility.

There are over 40 genes in humans that can lead to the risk of aggressive behaviors.But experts caution that their study, published in today's issue of the journal science, is limited and cannot be applied to the general population, or used to explain the high rate of violence in the united states.The maoa gene is responsible for the production of the protein monoamine oxidase.There are substantial differences, or variation, between humans in aggression, with its molecular genetic basis mostly unknown.These genes are related to the development of the central nervous system and communicate with the brain.

In humans aggressive behavior has become more nuanced, but its goals and causes are essentially the same.Doing so could greatly benefit aggressive.
