The genetic etiology of mathematical and reading (dis)ability has been studied in a number of distinct samples, but the true nature of the relationship between the two remains unclear. Data from the Netherlands Twin Register was used to determine the etiology of the relationship between mathematical and reading (dis)ability in adolescent twins. Ratings of mathematical and reading problems were obtained from parents of over 1500 twin pairs. Results of bivariate structural equation modeling showed a genetic correlation around .60, which explained over 90% of the phenotypic correlation between mathematical and reading ability. The genetic model was the same for males and females.
数学和阅读（障碍）能力的遗传病因已在一些不同的样本中进行了研究，但两者之间关系的真正本质仍不清楚。来自荷兰双胞胎登记处的数据被用于确定青少年双胞胎中数学和阅读（障碍）能力之间关系的病因。对1500多对双胞胎的父母进行了数学和阅读问题的评分。双变量结构方程模型的结果显示遗传相关性约为0.60，这解释了数学和阅读能力之间超过90%的表型相关性。男性和女性的遗传模型相同。
