Ruby and Yang are half-sisters confirmed.

Unless Qrow did his sister to some how create Yang, your previously mentioned theory is impossible. Didn't mean to be rude, I honestly didn't. But that above mentioned fact was given by Monty himself. Actually, IIRC, Monty said that they were not full sisters but were blood and as good as sisters. They could be cousins who regard themselves as full sisters because, before Yang was in her teens, neither of them had the slightest reason to believe that they weren't full sisters.

Okay, I'll drop this now but my point stands.
