But if an egg cell is somehow activated before that stage, it still has a full set of genes - and could develop into a functioning embryo clone. I challenge general_re and RJ Cogburn to find an article or piece of research that makes use of 'parthenogenesis' to stimulate a haploid ovum into forming a useful embryo, or any tissue that would be utilitarian in treating any human disease. If there is one, I have yet to find it, so I'd like to read it. I've speculated (due to the invitation at addressing the possibilities) that if a haploid could be stimulated to grow soemthing akin to useful tissues for research purposes only, that would be problematic, to me--since I count it improper tampering-- but it wouldn't be experimentation on an individual alive embryo. Would anyone like to take this further, offer articles or peer reviewed papers on parthenogenesis using haploid ova?

I should have guessed ;)

Okay, fair enough - I accept, but I'll need at least a few days to really do a proper search.

I think the discussion on this thread is on a little different topic, but I wondered if you saw this small segue provided by Scientific American: Monkey Cloning Failures Cast Doubt on Feasibility of Human Reproductive Cloning(FR thread)

As you already know, primate reproductive cloning is encountering problems at this time.
