What Your DNA Can’t Tell You

October 2, 2019

(The Scientist) – There are two key issues when it comes to predicting traits with DNA data, according to Daniel Benjamin, a behavioral economist at the University of Southern California. One is that there is very little scientific evidence to support predictions for certain phenotypes, including many associated with fitness or parenting behaviors. On the other hand, even for traits that scientists have carefully examined in large GWASs, such as educational attainment, polygenic scores are typically only useful for predicting differences between groups.
