Etiology of covariation between reading and mathematics performance: a twin study.

Twin research : the official journal of the International Society for Twin Studies - 1 Sept 1999

Knopik V S, DeFries J C

Abstract excerpt

The etiology of the observed relationship between reading and mathematics performance was examined by analyzing data from samples of same-sex twin pairs tested in the Colorado Learning Disabilities Research Center. Bivariate phenotypic and genetic structural equation models were fitted to data from 526 twin pairs selected for reading deficits (290 identical and 236 same-sex fraternal) and 355 control pairs (220...
