Theories of crime causation to begin to understand the idea of genetics and to line those up to criminal behavior would be to look much deeper into a person’s genetic nature there are so any leading factors that it would be hard to pin point one exact gene to say that is the criminal gene.

By examining monozygotic (identical) twins and dizygotic (non-identical) twins (who share 100% and 50% of their genetic make-up respectively), concordance rates (ie percentages to show how many twin pairs share the behaviour under observation) can help to indicate a possible genetic tendency.
