Well considering it is Ruby Rose and Yang Long I would assume they are half sisters and Ruby is essentially a bastard since the possession of her mothers last name would insinuate that whoever is Ruby's father isn't around. Xiao and Summer could have been together for Yang's birth but split up shortly thereafter. The explanation of Ruby refering to dad when speaking to Yang could just be a step-child acknowleding a step-parent's role as their parent. My main suspect for Ruby's father is Ozpin and Summer never came forward with Ruby as his child because she wanted Ozpin to be able to help the youth become effective Hunters and Huntresses or even maybe so if Ruby decided she wanted to be a huntress his father instincts wouldn't kick in and try to stop her because it is dangerous. Also Ruby's innate talent with Cresent Rose, the fact she built the thing herself and the fact she is Summer Rose's daughter might have played into Ozpin's letting her skip a year, if in fact Ozpin and Summer had been together.
