Glazer told us about companies providing something called polygenic screenings.

The process takes DNA from an embryo and analyzes it to provide insight into the kind of characteristics a child might have.

Some scientists warn that we still don't understand everything about the human genome and that any edits or changes, including unintended mistakes, could end up being passed down to future generations.
