Let me add... How about the NERD theory on Granites "attaching" to Hidden Gene Woma? Could this really be true and if so, I could see the Leopard/Pied thing in the same realm of becoming "attached", or they are just Allelic like some have proven them to be, or the original Leopards had already "attached" the pied gene, causing them to be what they are now.
I don't know, but what I do know is that we still have MANY years of figuring this stuff out... like the whole Banana "sex-link" issue... it boggles my mind... there is still much to figure out, holistically.
I agree with asplundii and Brant on their comments.
