Ghost is the same thing as whitesided. Some people hesitate to call them whitesided because they don't really have white sides. They're supposed to be pure everglades, but because they have yellow in the homozygous ghost/whitesided morph, a lot of people think they have yellow blood in them. Which is entirely possible, since a ton of the glades out there do have yellow mixed in. On the other hand, I've seen people who bought those as yellows, and have bred them with normal yellows to make hets. So, there're some mutts out there.
This guy came from Dwight Good, and is pure Everglades.




Sidenote- I don't know anyone who has really experimented with this, but the gene is the same as the whitesided gene in black rats, so, that says to me that there's some mixing between them somewhere along the line. All I know is I've seen pics of the offspring from a ws black rat x ws everglades, and the babies are ws.
