Who here has produced a lot of het and possible het Pieds? I have. And there is a definite difference. It's not just about stripes on the sides of the belly. There is a little more to it. Not all hets have the marker, but when a possible het does, you can pretty much bet on it. EVERY het Pied I have ever produced has the marker and about 50% of the possible hets as well......even my pastel hets.
Why else would the largest producer of Pieds in the world keep his possible hets and sell his 100% hets? Could there be something to it?
