HAVE WE LEAPT INTO COMMERCIAL GENETIC TESTING WITHOUT UNDERSTANDING IT?

Summary from the TLDR newsletter

Polygenic scores tally the contributions of many genes to particular traits to predict certain outcomes. They are probabilistic, not deterministic, as many traits are determined by environmental factors as well as genes. Potential parents using IVF are now able to choose embryos based on their polygenic scores. While it is understandable that parents want to give their kids the best chance of success, the practice may have unintended consequences on the human gene pool, not to mention the ethical implications.
