So I asked someone how to make a puma. And they told me a het puma breed to a het ivory. Well my question why say het puma when it's a codominate morph called spark. And a het ivory which is a dominate morph. I thought hets were only used for morphs involving recessive genes like a "normal female het 100% pied". I don't get it -_- does it mean the yellow belly carries a het for ivory? And the spark has the het for puma?

Hope someone can give me a "hets for dummies" kind of explanation. Because I'm just going nuts about it
