Hets are a lot more complicated than dominant and codominant genes. I would start with those first. Get 1.1 mojaves or 1.0 lesser 0.1 mojave or even 1.1 lesser and aim for BELs (blue eyed lucys). I would do either lesser x lesser or lesser x butter as they made the whitest least "dirty" bels.


Its really up to you though get what you like.
