I was looking at BP's on MM and I'm trying to figure out the naming sequence for some morphs. Like I know piebald is a recessive more so you need 2 copies of the gene or the animal is het and not a visual. But I don't understand why some morphs like when you add say champagne they look like a visual but are called 100% het piebald. So my question is why is what looks like a champagne piebald called a champagne 100% het piebald?
