I recently bought a ball python advertised as a 'Black Back Spider'. At the time I did minimal research on the black back part, found the information offered fragmented and confusing, and for the most part ignored it, happy with just taking home my beautiful looking spider.
Since then I have been researching more into 'black back' and no one seems cemented anything. So far I have got the following:
A) Black Back is just a phenotypical description
B) There is a 'Genetic Black Back'.

C) Black Back is another term for Het Red Axanthic, and breeders can use these terms interchangeably. Some people have said that this is what the het reds used to be called, until someone popped out a Red Axanthic and that took over and the term black back was dropped.
What are people's opinions here? My Black Back Spider for reference:
