Wouldn't wolves eat a coyote rather than breed with it? And yeah, this could be an escapee.
Yes. Wolves don't tolerate coyotes, just as coyotes won't tolerate foxes. The only way that I could foresee an inbreeding situation, was if it was under a controlled (domesticated) intro-fertilization situation. In the wild, wolves try to consume whatever coyotes they come across.
