There have been and still are many debates about how a person’s genotype can be a significant factor in the development of your personality, but more relating to criminality. It is very hard to say that your genetic make-up is not a factor in who you become as a person, but I fully believe that the environment also is a factor as well. Having a genetic predisposition does not mean that you are automatically going to inherit whatever trait that was passed down from your parents. Everyone has a choice in who they become as individuals; it all just depends on the environment that you are raised in and the people that are around you when you are growing up. There has been a lot of research on this subject and it has concluded that it is more often an interaction between both your genetic make-up and the environment that predicts criminal behavior.
Many scientists have stated that a person’s genetic make-up is the most significant factor in the development of criminality because they feel that parents who have been exposed to violence themselves or who actually commit the violent act can pass those traits along to their children. This gives their children a genetic predisposition to potentially become a violent person and commit a criminal act in their future as an adult. In many cases this can be true, but having a genetic predisposition for criminal behavior does not determine the actions of an individual and automatically make them a criminal for having a predisposition to violent. However, if they are exposed to the right environment, meaning that they are around violent people for a certain amount of time, then their chances are greater for engaging in criminal or anti-social behavior.
In every country or state, there is a wide variety of what represents criminal behavior, so a lot of research is mostly based on anti-social behavior rather than actual crime. One researcher studied a theory relating to sociopaths and their antisocial behavior. This specific study proposed a theory that a primary sociopath is lacking in moral development and does not feel socially responsible for their actions. This type of sociopath is a product of the individual's personality, physiotype, and genotype, which supports the theory that a person’s genotype is the significant factor in the development of criminality. There is a secondary sociopath that develops in response to his or her environment because of how and where they were raised. Living in an urban residence, having a low socioeconomic status, or poor social skills can lead an individual to being unsuccessful in reaching their needs in a socially desirable way, which can turn into antisocial or criminal behavior. This supports the theory that the environment is the significant factor in the development of criminality. With these studies, it shows that both the genetic make-up of an individual as well as the environment play an important role with what kind of person they are going to be as an adult.
