One man who has both is Michael Ibsen, Richard III's closest living relative. King will also be sequencing Ibsen's genome, to look for any other genetic similarities between the pair -- aside from the matching mitochondrial DNA, which allowed her to positively identify the Leicester remains as those of the long-dead English ruler.
"Theoretically, Michael Ibsen and Richard should not be genetically related any other way -- apart from the mitochondrial DNA -- after so much time, but it will be really interesting to see if there are other similarities," King said.
The project, which is expected to cost about $165,000 (£100,000), is being jointly funded by the Wellcome Trust, the Leverhulme Trust and Alec Jeffreys, the scientist who developed genetic fingerprinting, and who, like King, is a professor of genetics at the University of Leicester. It will be carried out in Leicester and at the University of Potsdam in Germany.
So could the controversial king ever be cloned? The experts insist that would be impossible -- for a host of reasons -- "you can't clone anything from fragmentary DNA," says King.
"Practically, you can't -- and morally, you can't," insists Dr. Dan O'Connor, head of medical humanities at the Wellcome Trust. "It's a whole different ethical issue."
