if a futa (girl with both male & female genitals) impregnated herself
is the baby considered a clone of her???

no. it more sperm donor than clone.

That is a really interesting question. Children get half of their genetic make-up from each parent. If the mother and father were the same person, then all of the child's genetic make-up would be of that parent.
I don't think it would result in a clone, but I would imagine the child would be awfully close to the parent. Maybe equivalent to a twin? I am not really sure.
Are there any geneticists in the house?

XKCD covered something similar. I know it's in the first book, What If? Serious scientific answers to absurd hypothetical questions

It's a very interesting question and I don't know the correct answer to it. The only thing or things for that matter I can say for sure is that if one futanari impregnates another futanari then it's not a clone. If it's a regular guy impregnating a futanari then it's not a clone either. There's probably a 5% chance of it being considered a clone due to the fact the futanari parent has both reproductive organs. So it's a very low possibility for the child to be a clone
