I'd say it's because Yang is indeed Raven's daughter, and that Branwen blood really boils over when she's in really heated fight, evidenced by her eyes turning red. Since Raven knows black magic, it wouldn't be too much of a surprise if Yang inherited some of her abilities. Though that could be another reason why Raven left, so Yang doesn't follow in her footsteps. Having her raised by Tai insured Yang didn't fall into darkness, as Raven did. So maybe Raven does have some affection for Yang, but not enough to be an active part of her life.
