So I've looked into it. It's just IVF reproduction where you take the eggs nucleus out and you put a sonomic cell in (any body cell). Bam, baby.
It turns out all the complications with Dolly were chance and a lot of 100% successful clones have been done of all kinds of species. It's not even that expensive to pull off.
I don't see an issue with it. If it ever got to the point where sci-fi level cloning was possible, that's where it would start to get weird.
