Parent ratings of temperament in twins: explaining the 'too low' DZ correlations.

Twin research : the official journal of the International Society for Twin Studies - 1 Dec 2000

Saudino K J, Cherny S S, Plomin R

Abstract excerpt

Twin studies of child temperament using objective measures consistently suggest moderate heritability for most dimensions. However, parent rating measures produce unusual patterns of results. Intraclass correlations for identical (MZ) twins are typically high, whereas fraternal (DZ) twin intraclass correlations are much lower than would be predicted from an additive genetic model. The 'too low' DZ correlations...
