Genetic & Environmental Influences on Criminal Behaviour

Several genetic research characterize at aiming the existence of genetic influence on criminal behaviour. Studies on twins also play a major role in determining the existence of such theories. Physical and mental disorders too contribute to such behaviors. Nonetheless researchers also prove the effect of environment on the criminal behavior. In contrary to it researchers also prove that not in all cases that the relevant environmental factors do influence the criminal behavior. The interaction of genetic-environment factors also contribute majorly to such criminal behavior. The relevancy of such biological and environmental testimony can play a major role while dealing with criminal cases.
