forensic psych- genetic and neural exp

Question 1

What do genetic explanations mainly depend on?

Answer 1

They depend on heritability and candidate genes.

Question 2

Who found the concordance rates and what were they?

Answer 2

Christiansen- found 33% concordance in MZ (identical) and 12% concordance in DZ (non-identical)

Question 3

What do the concordance rates suggest?

Answer 3

MZ share 100% genetic info but the concordance rates don’t show 100% concordance which means that criminality is produced by an interaction between the environment and genetics together as suggested by Mednick so the original diatheses stress model can be used to account for this.
