He's a normal leopard gecko as far as appearance, but because you do not know his parents and genetics, you cannot know for certain if he is carrying any recessive (hidden) traits.
In general, if you're looking to breed, it's good to do a lot of research first so you understand leopard gecko morphs and genetics. Once you've decided what you're interested in breeding, you should start by buying geckos from a breeder who can tell your their genetic history.
