As I recall, Uwe's original statement was that he felt the original ancestral population of aggies contained the genetics of all the color forms, and then they sorted them selves out in isolation. Personally, I think some color sports and changes should have occured over time. Look at the variants in angels that have popped up in the last thirty-five years or so. There are even at least three different forms of marble angel, each with its own genes.
