Gene link in grades
Researchers are studying the genetic basis of success in school.
A study that analysed 3 million people's full genetic code has found that DNA might explain 12–16 per cent of people’s education level.
The study conducted across Australian and Dutch universities also found that a lot of the impact of genes was likely to be due to indirect effects from the way genes interacted with the environment.
The experts say that many of these genetic variations can also help predict people's risk of a range of diseases, including heart disease, diabetes and asthma.
