I too think they are different. I would say that Butter/Lesser, Banana/Coral Glow, and Mystic/Phantom are the pairs of the same genes. Whereas, Cinnamon/Black Pastel and Sugar/Calico are different genes. You have to look at the combinations to see these differences, and even then, some combinations look similar, but others look different. Those that look different, lead me to believe that they are different, even if it is only 1 or 2 combinations. With Cinnamon/Black Pastel, I think the Super Pastel combination with each gene shows that the two genes are different.

With Sugar/Calico, look at Pastel Mojave combination with each gene.

I'm sure there are better examples than I have pointed out, but these are just the first ones that come to my mind. I think that the bottom line is that if there is one combination that is notably different, then they are similar but separate genes.
