Summary: Using genome-wide data from siblings in Add Health, the research team of Benjamin W. Domingue, Daniel W. Belsky, Dalton Conley, Kathleen Mullan Harris, and Jason D. Boardman discovered that adolescents’ genes were linked to how far he or she went in school (educational attainment). Researchers found that adolescents who had a higher “polygenetic score” – meaning their genes were linked to educational attainment – than his or her sibling were more likely to complete more years of school. This finding supports previous research showing that genes can influence educational attainment.

Excerpt from Phys.org: “…’the results of this study demonstrate that pioneering efforts such as the Human Genome Project are beginning to bear fruit in terms of genetic insight.’
‘Eventually, this type of research will help us better understand, across broad groups, the complex relationship between genetics, environments, and traits and behaviors, as well as help us better understand why school or government policies may or may not be generating desired objectives,’ said Domingue.”
