Well that just makes sense. Once DNA’s incorporated in one’s body in _some_ way, that it would incorporate itself in other ways isn’t surprising. So that I’ll go with.
That’s something I’m hoping for. CRISPr has my occasional attention and it’ll be nice to make minimal changes here and there to fix shit cheaply. But does child that comes after several abortions contain DNA from previous fathers? Eh, I’d need more proof than fruit flies. It’s not nothing but it’s not much yet.
