It is indicated that personality and genetics of a person have link with social influences like family and peer environment. The impact of parental role is also explained by psychological theories that state neglect or abuse from parents can also lead to criminal tendencies.

From these adoptive studies, it has been concluded that genetic impact on criminal behavior is significant irrespective of gender although females are more subjected to individual genetic risk than the males. Moreover, it has been observed that parents with records of petty
