The more I've thought about it, the more complicated it gets. It's not just a lucy that can be white. A lesser/pied is all white too (not the super of the lesser, just the lesser and pied). Then the axanthic/albino is pretty much white too. The formula wouldn't be complicated if you had a complete list of recessives, dominant and co-doms(counted twice) and just wanted to know all the combos. But I'd really like to single out meaningless combos and that's very difficult because you don't know how different genes might react to each other until it's done. Who would have thought the Phantom would produce a lucy with a lesser/butter but not a mojave? Who would think a Lesser/Pied would be all white but not a Mojave/Pied?
