What are Wyoming Whites bread from?

[US Marine Coral]

I understand that Platinums are Perc's and Wyoming Whites are Occ's, but what are they bread from and what is the difference? I have never seen W Whites in person but they look bigger/thicker. Can anyone help me figure out the difference and where they "come from."

"C-quest says that the strain started showing up almost three years ago in the batches of three different older pairs of Amphiprion ocellaris which looked completely normal in every respect. The first crossings of the Wyoming Whites yielded only 10-15 solid white fish per clutch. Over the last couple years C-quest has been trying different crosses and pairings to encourage the Wyoming Whites to breed true and they now have much more stable genes which should yield a high percentage of fish with the all white body coloration."
