When It Comes to In Vitro Fertilization, Is Three a Crowd?

Your grandchildren might have to pass AP Bio before their parents can explain to them where babies come from. Britain's Human Fertilisation and Embryology Authority has launched a public survey to discuss the ethics of using three people to create a baby, the BBC reports. The topic has come up thanks to a new treatment that could cure hereditary mitochondrial diseases — which cause weak muscles and heart and can be fatal — by altering the makeup of the egg with a donor's healthy mitochondria prior to in vitro fertilization. The technique is eliciting "slippery slope" arguments from conservative groups because it is technically a "permanent" form of genetic modification that would be passed on to future generations. So her kids won't have mitochondrial diseases either?! Bring it on, Dr. Frankenstein.
