Well, like Jorge mentioned, there are some ghosts that can display a pink casting, and other's that are a product of this so-called "strawberry" mutation. That young adult belonging to my friend is definitely outstanding, but He, nor I have a clue to it's exact genetic makeup. It was simply sold to him along with many other types of corns as simply a ghost.
In any case, I told him a long time ago that his ghost was the nicest one I have EVER seen though. That is hard for anyone to dispute..LOL!
I will try to remember to ask him if he ever got any more info on it.
Seems that I recall some years ago that Kathy Love had some "special project" ghosts that looked very similar with ruby-red eyes too. I guess that could have been the infancy of this "strawberry" gene thing we hear about now in recent years.
Don't count on seeing high numbers of these very pink ghosts all over peoples tables just quite yet though..LOL!, but as Jorge said earlier, you might be able to find a couple here and there for a pretty good premium possibly.
This even has me wondering now if my buddy EVER produced any ghosts that resemble the adult that I posted. I would love to have one that looked like his adult any day of the week..LOL!
