Yes, the life state transfers. Cure the donor sim before grabbing their DNA/cloning from the sample (if they turn after you collect the sample; I don't know if it will transfer to the clone if the donor turns into a supernatural after collecting the sample but before cloning, but you can never be too safe).
Also, one odd little thing I noticed with cloning sims is that the clone occasionally comes out with different coloring. I cloned a few sims over the course of my dynasty; two came out looking exactly like their donors, but two others came out nearly alike, but with a different hair or eye color.
The interesting part was one who was cloned from a blue-eyed donor, but came out with black eyes. While her donor was blue-eyed, the donor's parents both had black eyes. I thought it was a pretty nice throwback to her ancestry. Then there was one cloned from a donor with black and blue hair; the clone came out with dirty blond hair, in spite of absolutely no one in the donor's family being dirty blond.
Clones always have the same exact facial features as their donors, though, so I was able to preserve the most important parts of my beloved townie genes without any fear.
