They are double hets as the "Ghost" cal kings are Palomars...or rather originally from a wild-caught Palomar. The Ghosts are no longer locale specific. I got my Ghost from Brian at B.H.B. Enterprises and said that the original Ghost was a Palomar...but he obviuously outbred it to other cal kings (albino, etc..).
And yes, the term "Ghost" is not genetically accurate no more than "Snow" is in cal kings either. I chose to keep the term "Ghost" because that is what they were advertised as from B.H.B. A single recessive gene.
