Ae and I interact in dosage effects. In all irir that they are in. For instance Forever Blue has both. Cross Forever Blue t oa white or yellow (for example) and you will get some purple seedlings, where you get Ae without I.

The plicata alleles are totally recessive, so don't show any partial effects as with a partial dominant.

Different combinations of pl, pl-lu and pl-gl will show different patterns, even without I being present. So what you have after anthrocyanin is removed from all but center areas of petals (falls) will also be different patterns. So basically as many patterns with anthrocyanin in center of falls as there are plicata variations with anthrocyanin on rest of flower.

So what would be the genetic makeup of things from "line-and-speckle" breeding that show similar patterning but not lined-and-speckled? The examples I'm thinking of are the cultivars 'Beacon Of Light' and 'Stir It Up'. I'm guessing that they don't have a full complement of 4 plicata genes, but instead 2 or 3 copies, but still interact with Ae and I?
