question 5

○ there is no evidence that genetic factors explain 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 6
the results of adoption studies
○ suggest that neither the criminality of the biological parents nor the criminality of the adoptive parents affects the child

○ support the claim that the criminality of biological parents has more influence on the child than does that of the adoptive parents.

Explanation:

• Question 4: XYY syndrome has been associated with studies looking at a link between chromosomal abnormality and criminal behavior. Males with XYY have an extra Y - chromosome.
• Question 5: Twin studies have provided some support for the idea that genetic factors can increase the risk of criminality, though it's not a definitive causal relationship.
• Question 6: Adoption studies have suggested that the criminality of biological parents may have more influence on a child than that of adoptive parents.

Answer:

• Question 4: D. XYY
• Question 5: A. there is some support for the hypothesis that some genetic influences increase the risk of criminality
• Question 6: D. support the claim that the criminality of biological parents has more influence on the child than does that of the adoptive parents
