Het to het breeding is a long process. Lots of variables. If a dreamsicle is your goal I'd save up and buy a visual piebald and a visual lavendar albino to breed and then all of the off spring are 100% double het. Keep in mind that whichever one is the female you would want to buy it a year before the male so they mature about the same time if you are buying hatchlings. Then you breed brother to sister for your chance at getting the dreamsicle. Worldofballpythons.com and owalreptiles.com both have genetic calculators that will let you see the odds of what x what = what. Also vmsherps.com has some good materialon genetics that I found very helpful. Also john berry's book guide to ball python morphs volume 1 is a cook book for breeding morphs. Not sure I got the title right though. Good luck and doing your home work is the biggest factor at getting where you want to be.
