If you breed the ghost to the spider, all the babies will be 100% het for ghost. Not 50%. Jay_Bunny is right though, to suggest that if you go that route, be sure ONLY the ghost gets a chance at its mate. Otherwise, you can't be 100% sure which snake fathered the babies, and then won't be sure if they're hets or not.
