Well with alot of research, if your snake came from a pet store not a breeder it is more than likely just a normal ball python. So if you were to breed that snake to another normal all you would get are normals. Breeding a normal to say a pastel would give you pretty much a clutch with half looking like mom and half like dad. The only way you will produce morphs is if you start with morphs or if your snake carries genes to create a morph. Snakes that carry those genes are sold as such, since they are worth more since in theory you know what you will get when it breeds. There is tons more to know so LOTS of research and time and you should be able to get the idea of how it all works.
