Achievement at school and performance on the Dominoes test, the Differential Aptitude Tests (DAT), and Griéger's Characterological Questionnaire of 45 monozygotic and 46 same-sex dizygotic pairs of twins were analyzed using a new linear model for familial corrrelation. For 14 of the 20 sets of data, the genotype's contribution to the total variance is estimated to be higher than 50%. The effect of common environment seems to be important only for achievement in Arts.
运用一种新的家族相关性线性模型，对45对同卵双胞胎和46对同性异卵双胞胎在学校的成绩以及在多米诺骨牌测试、鉴别能力倾向测试（DAT）和格里格性格问卷上的表现进行了分析。在20组数据中的14组里，基因型对总方差的贡献估计高于50%。共同环境的影响似乎仅对艺术方面的成绩较为重要。
