There is no such thing as 'full blooded' even in the Narutoverse. Even the clans who supposedly practiced inbreeding most likely weren't purebloods. Just because Uchiha mainly shagged Uchiha and Hyuga mainly shagged Hyuga doesn't mean that in the 1000+ years span they had no 'fun' with outsiders as well.
