Does higher concordance in monozygotic twins than in dizygotic twins suggest a genetic component?

Human heredity - 1 Jan 2001

Guo S W

Abstract excerpt

It is widely regarded that twins can be used as a natural experiment to subject hypotheses to empirical testing regarding the contributions of genetic factors to phenotypic variability in human traits, especially behavioral traits. In genetic epidemiology, a higher concordance rate in monozygotic (MZ) twins than in dizygotic (DZ) twins is often taken as prima facie evidence for a genetic component. While twins...
