I recommend FUT over FUE. Why? Because with FUT if you want to get future transplants it allows you to get the max amount of grafts unlike FUE. Sure the scar is linear, but imo it looks a lot better than having tons of tiny holes in the back of your head. The cost is cheaper too by quite a bit.
Now to answer your question, in regards to hair cloning I’d say most likely no since unless you’re harvesting a good amount of your donor (nearly all) then you’ll have hair left to clone in the donor. I don’t see why they can’t just take a transplanted hair and clone it too though.
Tldr; I’d rec a FUT & you’ll most likely be able to participate in future treatments/cures
