Whites may not have showed up, but that was only by certain luck -- a white carrier will breed a carrier who will breed a carrier and then another carrier to breed another carrier, and so on. So there have always been carriers.

Same reason I don't know if Visa carries tervuren. It's unlikely, but still possible. Won't know until I breed her to a terv, or a terv carrier (Solo's daddy is a terv carrier -- wouldn't have have been just awful is he was the only one AND a terv! I so badly wanted a groen lol).
