From the Ted Talk by Jennifer Kahn: Gene editing can now change an entire species -- forever
Unscramble the Blue Letters
OK, the other piece of bad news is that a gene drive might not stay cionnefd to what we call the tgeart species. That's because of gene flow, which is a fncay way of saying that neighboring seceips sometimes interbreed. If that happens, it's possible a gene drive could cross over, like Asian carp could infect some other kind of carp. That's not so bad if your drive just promotes a trait, like eye color. In fact, there's a decent cachne that we'll see a wave of very weird fruit flies in the near future. But it could be a disaster if your drive is dgeenid to eliminate the species entirely.

Original Text
OK, the other piece of bad news is that a gene drive might not stay confined to what we call the target species. That's because of gene flow, which is a fancy way of saying that neighboring species sometimes interbreed. If that happens, it's possible a gene drive could cross over, like Asian carp could infect some other kind of carp. That's not so bad if your drive just promotes a trait, like eye color. In fact, there's a decent chance that we'll see a wave of very weird fruit flies in the near future. But it could be a disaster if your drive is deigned to eliminate the species entirely.
