I wish I knew the source of this information, but I had read somewhere that all cannabis has evolved from Ruderalis. We are talking the a long time so don't anyone get excited. We're talking the evolution of a genus here. Being such, then all cannabis has the autoflower gene.
Also there are seedbanks who claim to have bred all ruderalis genes OUT of their autoflowers. I don't remember the names, but they do exist.
