Purpose: The aim of this study is to establish which specific cognitive abilities are phenotypically related to reading skill in adolescence and determine whether this phenotypic correlation is explained by polygenetic overlap. Method: In an Australian population sample of twins and non-twin siblings of European ancestry (734 [less than or equal…

We examined the association between reading and general cognitive ability (g) in a population-based sample of 6,476 pairs of 7-year-old twins. Additive genetic influences largely accounted for individual differences in reading and the covariation between reading and g. Furthermore, both genetic and shared environmental influences on reading and g…
