question 12
according to studies of twins,
○ there is no evidence that genetic factors explain criminality
○ there is some support for the hypothesis that some genetic influences increase the risk of criminality
○ there is a strong causal relationship between genetics and crime
○ there has not been enough research comparing monozygotic twins to dizygotic twins to make any conclusions.
question 13

Explanation:

• Question 11: Studies have looked at the XYY syndrome where males have an extra Y - chromosome and its potential link to criminal behavior.
• Question 12: Twin studies provide some support for the idea that genetic factors can increase the risk of criminality, but not a strong causal relationship.
• Question 13: Adoption studies often support the claim that the criminality of biological parents has more influence on the child than that of adoptive parents.
