College attainment is one of the few phenotypes to have substantial variance accounted for by environmental factors shared by reared-together relatives. The shared environment is implicated by the consistently strong parent-to-offspring transmission of college attainment. The mechanisms underlying this relationship remain unclear. We use genetically informative methods with a longitudinal, adoption sample to identify possible environmental mechanisms underlying parent-offspring college transmission.

共享环境在大学成就中的作用：一项收养研究

大学成绩是为数不多的由共同抚养的亲属共享的环境因素引起的显着差异的表型之一。共享的环境与大学成绩的持续强烈的父母对后代的传播有关。这种关系背后的机制尚不清楚。我们使用具有纵向收养样本的遗传信息方法来确定亲子大学传播背后可能的环境机制。
