Hypo means basically orange ghost. When you see a snake advertised as a "ghost" or het ghost you can assume it's orange ghost/hypo and vice versa. If it's any other type of ghost like a green ghost, peach ghost, etc, it should be advertised as such.

For many breeders the most politicly correct term for orange ghost is hypo.

Since the orange ghost/hypo is the most popular and the one that is most highly available, I assume that is the gene that both of your snakes carry. The best way to know is by seeing the parents. The orange ghost/hypo is of the brightest, most washed out, and has a nice orange glow to it.
