Kent, Thanks for your interesting information. I would guess then that to determine a classification for Stage Presence, you would have to check the parentage to determine the genotype. But if you cross a plicata with an amoena, would it not be possible to have the offspring exhibit both characteristics? Gypsy Lord comes to mind..having the white zone, plus the edge of a different color, and I think it has a white standard. God, it's been decades since my genetics class in college, lol. Tom
