Cinnies and blonde pastels (blonde is just a different line of the pastel morph, and cinny is NOT the same thing as pastel) are two different base morphs, and both are codominant, meaning that if you breed a cinny or a pastel to a normal statistically you get 50% normals and 50% cinny or pastel (depending on what the morph you bred was), and breeding two cinnies or two pastels together will give you statistically 25% super forms (super cinny, an almost patternless black/brown snake or super pastel, a more extreme form of the pastel morph), 50% either pastel or cinny (again depending on the morphs you bred) and 25% normal. To get some in a clutch you have to start with a morph parent...
Oh, and breeding a cinny and a pastel together gets you 25% pewter (pastelxcinny), 25% cinny, 25% pastel, and 25% normal. ^-^
Hope that helps!
