It cant be the same morph if you get different results. Take the cinny and the black for example. What they produce are different. Both supers are different, the sterling and the silver streak are different, when combined with the pied gene also different etc. Now are they close? Maybe but still different. Now butters and lessers are alot closer to eachother then the cinny is to the black. Its all about subtle differences in the morphs nowadays. Look at all the different variants of pastels. Lemons, blondes, jungles, citrus etc, then you have all the different lines from grazianni, bell, stonewashed, etc. Its all about variants. All these subtle morphs are building blocks for combos. Thete are so many more subtle morphs then thete ever was before and thete will be more. The key is selective breeding to unlock the potential for combos
