  1. What is Crime?

  2. Why?

  3. How can we test if genes play a part in criminal behaviour?Who can we study? • Twin studies: • monozygotic twins (MZ-100%) • dizygotic twins (DZ- 50%) • Adoption studies: • Find out the effects of genes and the environment • Family studies: • Study rates of schizophrenia in different relatives. E.g. compare concordance rates between mother and child.

  4. Concordance rates • What is a concordance rate? • This is the coefficient value that is worked out by correlating the crime rate between 2 groups of people e.g. concordance between parent and child • The correlation coefficient tell us the likelihood of both parent and child engaging in criminal behaviours • The higher this number is the more chance there is of criminal behaviours developing • This can then be represented as a percentage value.
