Twin Studies Have Suggested That There May Be a Link

Twin studies have suggested that there may be a link between heredity and crime. However, recent research by Carey and by Rowe and Gulley indicates that much of the effect previously attributed to heredity may be due to:

A) differences in the ways in which parents treat identical versus fraternal twins
B) the effects of sibling interaction and imitation
C) misclassification of identical and fraternal twins
D) similarities in the food preferences and diets of identical twins
E) police bias in decisions to arrest youths whose identical twins have previously been in trouble with the law
