I seem to recall the Q arising when I was a dub and the answer given was that Jehovah would reassemble the person from the same ashes and dust that the corpse had become.
No, I think that is the traditional resurrection belief, that the former body is reconsituted. I recall the Society always argued that the body cannot be reconstituted because it has become incorporated into other living things. They viewed the body as a completely new recreation (necessitating a quasi-docetist belief regarding Jesus' post-resurrection appearances).
