Very nice. Any relationship to Raul Gomez's line (either on the pied side or that "normal" female's side)?

I've often wondered if the lines of pied with more co-dominant tendencies would tend to produce higher whites. But does either the tendency to show in hets or the tendency to produce high white pieds come from variations in the pied mutation or from other genes in some lines or are they unrelated and either or both really random?

It does look like Graziani might have a fully co-dominant pied allele in the leopards but excluding those the sporadic het indicator belly in other pied lines is a very interesting can of worms.
