Semantics of what constitutes a clone from a scientific perspective. It is phrasing that is correct, but leaves laymen with the wrong idea.so if shes test tube born why all mwaterials say shes his clone? test tube kid is not the same as a clone
Gonna coin some terms on the spot;
For the sake of distinction, we could consider characters like Madelyne Pryor and Ben Reilly to be Mirrored Clones - they were designed to explicity work as replacements for their genetic progenitor as completely as possible, as if they stepped out of the mirror.
Meanwhile Laura Kinney (and Gabby et al. by proxy) and Superboy (which I know is DC, but was the first example that came to mind) would be Progenal Clones. They are mixes of an intended genetic progenitor and a secondary stabilizing donor in such a way as to emulate the production of a child, and that embryo is then put through the rest of the cloning process.
Hope this gives someone a better way of comprehending the differences. They're slight, with respect to the actual science of it, but clearly a line between needs to be drawn.
