>I have an axanthic ball python that bred this year and produced het babies. I did not purchase him from a breeder, and the gene is not proven (yet). Does anyone know how such "papers"are obtained? Do I need to wait until the line is proven?
There is no organization that issues such papers. You issue your own to the people who buy your animals. You could wait til the line is proven. Or you could show pictures of the parents to the prospective buyer and tell him that the axanthic is of unknown ancestry (wild caught or whatever) and that you have not yet proven that the condition is genetic.
