Joseph (2001) Criticized the Findings of the Minnesota Study of Twins

Joseph (2001) criticized the findings of the Minnesota Study of Twins Reared Apart, and suggested that

A) studying twins reared apart is not as useful to behavior genetics as studying children adopted before the age of one and children adopted after the age of one.
B) the twins' level of similarity should be compared to the similarity between pairs of unrelated strangers with similar characteristics.
C) the twins' level of similarity is more likely a result of cultural variation than genetic inheritance.
D) studying dizygotic twins raised apart and together is a better measure of genetic similarity than studying monozygotic twins.
