Incog-
I'd try a Socrates act with dd to see what her real concern is about clones. Does she worry that YOU might be replaced by a clone? Maybe she doesn't understand that even a clone needs time to grow into an adult.
I'm not in favor of human cloning, but remember when "test tube babies" were big news? However the child is conceived, it still must go through all the usual patterns of growth and discovery. Cloned babies would not be born knowing all that their donors do, and they will not be adults any sooner than any other baby.
Do you think this would help?
