I forget, have true ghosts been produced from lines other than TSK axanthic? Some day we might find two mutations close together on the same chromosome making it very difficult to make the double homozygous combo. I did get to see one of the TSK true ghosts (or just ghost as they call it, they point out that what most call ghost should be called hypo and "ghost" reserved for the combo) at the Denver show a little over a year ago and it was very impressive.
