Within this paper we will discuss the merits of the idea that genetics are a source for criminal behavior. As well as some of the strengths and weaknesses of the evidence surrounding genetics and crime and In closure what would be some of the repercussions in the criminal justice field if the existence of the criminal gene is proven to be true.

There are so any leading factors that it would be hard to pin point one exact gene to say that is the criminal gene. Although it is very possible that certain genes may influence the chemistry in an offender’s brain therefore resulting criminal behavior. But there has been studies proving that environmental as well as genetic influences have a much broader form of play in today’s criminal behavior. Low levels of serotonin have been proven to disrupt ones behavior for it is a link to certain actions, such as impulsiveness. It is a combination of factors and lack thereof sufficient chemicals one’s body may produce. For example, David Garaedian was a mild timid quiet gentleman who happened to murder a female due to the pesticides he had been working with. The reason why was for the dramatic change in the acytecholine in the hypothalamus. This alone shows that there are severe links due to biochemical factors in leading variables such as environmental conditions, allergies, and radiation. Studies in adoption vs. biological parents have been found to be only a small factor of adopted children develops a criminal background. Schulsinger(1972) performed a study and found that 3.9% of adopted children had a criminal background. Throughout a lot of the studies and concerns, it still seems to show that through all things , the fact that poor environment,...
