Weren't there a few female athletes who came up with an extra chromosome? I
think they were XXY ... I suppose it might be a trillions to one chance for
something like that to happen in a case of twins.
However, I can't recall what the Olympic people did about them. If it's a
natural genetic mutation, could they prevent these athletes from competing?
