It's already been stated as fact outside the show itself that Ruy and Yang are half sisters by blood. Yang's parents are Taiyang and Raven. Ruby's mum is Summer. Therefore, Ruby's dad has to be Taiyang in order for them to be half sisters.

Qrow might be her father figure, but he is not related to Ruby by blood at all.
