Epigenetic Algorithm Accurately Predicts Male Sexual Orientation

By using epigenetic information from just nine regions of the human genome, a new algorithm can predict the sexual orientation of males with up to 70 percent accuracy. “To our knowledge, this is the first example of a predictive model for sexual orientation based on molecular markers,” said Tuck C. Ngun, PhD, first author on […]
