Just because they're sisters doesn't mean they're relation is by blood. The trick thing about this topic is that it all depends on what people mean when they say "related", 'sisters" or "family". It could mean that one is adopted, both are, or neither. It's pretty hard to tell given how open to interpretation all of these statments are.

Hell, you could argue that they’re full blooded sisters because they said sisters, and not half sisters, and that last names just work strangely in the RWBYvers.
