Mrzzy - true re: "clone" - what I meant tho' was that perhaps the embryos that are resulting are the result of the inserted nucleus - and the haploid dna of the egg nucleus "drops" out in the first division - much as during the formation of the polar bodies (There is a similar thing that occasionaly happens in naturaly occuring triploid plants - such as apples) This would result in what they are currently terming "clones" - an embroyo resulting from the nucleus of a somatic cell - though with extra-nuclear dna and rna from the donor egg.
