this is a difficult question to answer, but i think there are only a few parents to all the ORA picasso clowns. If i recall correctly, they are not inbred animals. I believe the story goes that ORA identified some wild caught adults that throw this picasso mutation (which are weirdly misbarred) at a higher frequency. The frequency is a little higher than 1:10,000, but its more like a few/100. Same goes for the "nked morph, these are from a few pairs of wild caught that happen to produce misbar'ed at a higher frequency.
As mentioned above breeding these pair together does not guarentee you get all nkeds or picasso or snowflakes back.
