A genetic explanation of schizophrenia would be supported by which of the following choices?
A)Higher concordance between MZ than DZ twins.
B)Similar concordance rate between MZ and DZ twins
C)Relatives of someone with schizophrenia are no more likely to have schizophrenia than anyone else.
D)MZ twins reared together are likely to share the disorder.

A higher concordance rate between MZ twins than DZ twins suggests a genetic factor in the development of schizophrenia. This is because MZ twins share 100% of their genes, while DZ twins share only 50% of their genes. If genes play a role in the development of schizophrenia, we would expect to see a higher concordance rate in MZ twins.
