Ditto what Bogertophis said. You want to take some serious time to plan a breeding project and get to know the market and morphs you want to work with. I can tell you right now as a kindness since you happen to have a combination of morphs I am quite familiar with, that breeding those two together isn't the best idea for a new breeder. Ivories are a dime a dozen when it comes to market value, which 1/4 of your clutch would end up. There 164 PAGES of them up on morph market as we speak, and while some might show hefty price tags, you have to understand how Super Yellow Belly actually acts to achieve slightly different color differences to understand how difficult it is to produce one that shows nice color, let alone enough color to display any other morph in the combo. Plain YB sell as poorly as Normals. Enchi and YB together can accomplish amazing, expensive things with the right other morphs. Ghost though? That is going to undo so much of the beauty that is achieved by that combo, while it can be so amazing with other combos.
If you are smart you will take a lot of time to research and think before buying any more animals you plan to breed so that you can have a project with something that stands out from the many animals flooding the market. Otherwise you are going to end up with a bunch of animals that either you won't breed or you can't sell the offspring and end up quitting out of frustration.
I'm not trying to diminish your excitement and passion for the hobby just so you understand. I'm trying to keep you from moving too quickly, to preserve those amazing feelings and avoid burnout. I am very familiar with YB complex, particularly with Banana and Enchi, so if you want to ask questions or bounce things off me to really come up with a solid plan, I'm more than happy to help so that you have the best chance for success. Feel free to drop a new thread in the "morphs and genetics" section or DM me if you like.
