Palmettos are produced through simply recessive inheritance and are more akin to a Leucistic form than P/S. A P/S Palmetto would most likely look the same as any non-P/S Blood. The Pied BP gene is very different from the P/S corn one and more similar to the genetic inheritance of the Pinto coloration in horses. We have yet to stumble across a genetic means to have corns that are similar to Pied BPs. I can't wait until we do though because it is my favorite of the BP morphs.
