tveguy3 said:Well, I did a "small" amount of research (a little knowledge can be dangerous), anyway, I found out some things about anthocyanin pigment. A part of their job in a plant is to absorb some of the color spectrom of the sun light, which would explain the almost glow of the Glaciatas, as they would reflect more light then obsorb it? Just a guess. Anyway, thanks, Kent for that explanation, I think that helped me a lot. Now one thing remains, How do you know about horse color genetics? A horse can carry both of the genes, one for Tobiano, and one for Overo, and they will look mostly white with a few patches of other color. Can an iris carry both the Plicata, and the Emma Cook patterns? If they are separate alleles that should be possible. Wonder what they would look like?

My grandparents were ranchers. I grew up around horses, although I haven't been on one in about 20 years.

Plicata is a recessive trait, so irises can carry the genes for it without expressing it. A number of hybridizers, particularly Joe Ghio and Tom Johnson have been working on combining plicatas with other irises. At least part of the result is what Joe Ghio calls the "Line & Speckles" pattern.
