So Ruby and Yang are sisters, correct? And a lot of the fandom sees one of them as being adopted. So who is the adopted one? I have four theories.

1. Ruby's parents died somehow, which is at least half true.

2. Both of Yang's parents either died or disappeared, or maybe unadopted Yang, and Ruby's father took her in. Or maybe this an theory one crossed over, so Yang's father took in Ruby. I think this is the most likely because in episode 4, The First Step, after Yang gave Ruby a lecture on meeting new people, Ruby said that she sounded like 'dad'.

3. And then the least likely, Ruby's mother, and Yang's father died. And then Ruby's father and Yang's mother got together.
