that pretty much sums it up. kevin says its a monogenetic trait (like every other trait we call a morph) and it has a super form. Yet offers no proof of this claim. Others say it is polygenetic, where multiple genes play a factor in the trait. This seems to be the case looking at inheritance patterns and the fact it pops out of nowhere in multiple collections. Pastel is a monogenetic trait. How yellow/brown it is, the blushing, reduced or not the pattern is are all polygenetic traits that are controlled by multiple genes we don't recognize by themselves.
Ohhh ok, thanks for the explanation. I appreciate it.
