an open-source repo for embryo selection

According to LessWrong, developer Dawn Drain has released an open-source tool for polygenic prediction and embryo selection. The repository uses genetic scores from publicly available databases to predict traits including intelligence, height, and disease risk. For parents undergoing in-vitro fertilization, the tool helps select which embryo to implant based on these polygenic scores. The system converts genetic predictions into measurable health outcomes, though Drain acknowledges the practical gains are modest. Current polygenic scores correlate with actual traits at rates between zero point three and zero point six-five, meaning the benefits of selecting among a handful of healthy embryos are relatively small—less dramatic than you might expect.
