Glad I could help!

She went from a few specks of white to suddenly a connected stripe one shed, but I think since then it's either slowed down or I'm just used to seeing it. It's interesting that yours goes over the black areas, I wonder if hers will eventually do that.
Sadly I think this disproves our "het G stripe" theory, seems like either something to do with the yellowbelly, or a random occurrence on another gene and the yellowbelly is a coincidence.
