Not certain about all the nuances of Het. Pied markers, I know most people are all over the place with them right now, but I can pretty confidently say nothing about this snake rings "Leopard". Also, I don't think saying that Leopards produce het. Pieds is particularly accurate either? Leopards are allelic to Pieds but this don't make them a true het., it just means they're compatible and can also be used to produce Pied animals (allegedly). I mean, Lessers/Butters and Mojaves are allelic but no one ever says that a Mojave is also Het. Lesser. :/
