OWL is just one way of specifying relationships. When you build relationships in Protégé you end up with a .owl file that can be imported into Fuseki. The triple-store will then contain triples describing your objects and their relationships. Some of the relationships stored as triples will be those you set up in Protégé. Domain and range information for instance. Subclass and superclass. Same-as.Disjoint-with etc. All this is stored in the triple store along with your objects and explicit relationships.
You create an inference model from the data using Jena, then query the inference model. The reasoner you use on the model will parse the rules and make inferences. So if you make cats and dog each a subclass-of mammal and mammal a same-as of animal, a SPARQL query listing all animals will find dog and cat. Read the link I provided for more.

The Jena rules we use are not OWL specific? You mean rules in the Protege?
