Those individuals proved those morphs or lines out as being genetic or the first captive example of the morph and in turn get to name it whatever they want. Kind of like producing a world's first morph from dinker animals or proven base morphs that combine into a 5, 6, * gene monster: you could name it PAM Cooking Spray if you wanted to and had the copyright privileges from PAM, lol!
As to coming up with your own line: dinkers, imports from Africa, "different" looking "normals", etc. and then a LOT of time, energy and money into proving the animals and their traits out as genetic. Or you might hit the one in a million odds and luck out with a pair that proves out as something entirely new on your first try.
