Racists could try and build in genetic triggers to cause any "mixed race" grandchildren to die in the womb. This is impossible to do in general but someone might try. Imagine someone engineering "Aryan" children whose children must be blond and blue-eyed and will self-abort if not. If this happens, you'd imagine a cottage industry of gene-drive-removers... and then genetic DRM mechanisms in turn. Not a good time for anyone. https://en.wikipedia.org/wiki/Gene_drive https://en.wikipedia.org/wiki/Gene_drive
