Of course this necessitates HAVING other eggs, which we already established are in short supply. But thankfully, those other eggs don’t need to come from the same woman. You can get donor eggs without too much trouble. And if you don’t care much about the donors’ DNA you can get them for quite a bit less money.
So twiblings using donor eggs would still have mitochondrial DNA from the donor, right?
Yes. In fact, we already do this kind of treatment for people with mitochondrial disease. The offspring this produces is often casually referred to as a “three-parent baby”, even though the “third parent” (the egg donor) only contributes about 14 genes to the child.
