In ball pythons ghost and hypo are the same thing. The confusion come from the boa world which named the ghost morph first. Which is a combo of axanthic and hypo. In the ball python world this combo is called "True Ghost". I prefer to use Hypo over ghost.

There are a number of lines in the hypo morph. Like Snakekeeper extreme, NERD orange ghost, yellow, green and so on. Not all lines are compatible. The most common is the Orange hypo. Which is compatible with Nerd, orange, SK extreme and a line of yellow.

If you are purchasing a line of hypo just make sure it is compatible with the Orange line and you should have no problems.
