Genetics: Genes may influence university choice and achievement


今回、Ziada Ayorechたちの研究グループは、3000人の被験者と3000組の双生児から得た遺伝情報を解析して、若年成人の大学教育に関連する指標の個人差を遺伝子によってどの程度説明できるのかを調べた。Ayorechたちは、一卵性双生児と二卵性双生児を比較して、Aレベル試験の結果(合格すれば英国の大学への入学資格が得られる)の個人差の57%、志望大学の選択の個人差の51%、志望大学の質(学業面の評判、卒業後の就職見込みなどの要因によって測定される)の格差の57%、および大学での学業成績の個人差の46%が遺伝的要因によって説明されることを明らかにした。



Genes may, in part, influence young adults’ decision to go to university, which institution they attend and how well they do, according to a study in Scientific Reports.

Ziada Ayorech and colleagues analyzed genetic information from 3,000 individuals and 3,000 twin pairs to examine the extent to which genes explain differences in measures related to university education between young adults. By comparing identical and non-identical twins, the authors found that genetic factors explained 57% of the differences in A-level exam results (used to determine university entrance in the UK), 51% of the difference in university choice, 57% of the difference in the quality of the chosen university (as measured by factors including academic reputation and employment prospects), as well as 46% of the difference in achievement at university.

Previous studies have shown that genetic factors explain a substantial amount of the differences between students' educational achievement in primary and secondary school. However, the authors suggest that this genetic influence continues into university. They argue that this may be because university allows students freedom to choose classes and environments based on their genetically influenced aptitudes. Furthermore, they found that, although the ‘shared’ environment, such as family or school, influenced the decision to go on to university, it was individual or ‘unique’ environments that explained part of the differences in university achievement.

As well as using twins to untangle the genetic and environmental influence on measures of university success, the authors also used DNA alone to show that university success was influenced by genetics.
