about the morph:
if its a dominant or codominant morph, you should be able to identify it by just inspecting the snake you have. And i dont see a morph here.
if the snake is heterozygous for some recessive morph, if you breed it to a normal you will only get normals and dont learn anything. You would need to know what specific morph it is het for and then breed it to the specific morph. or you would need to try each one individually, like: breed to albino to see if its maybe het albino, breed to ghost to see if its maybe het ghost, and so on with clown, axanthic, G-stripe, pied, caramel, ... .. .
you could try to get pictures of the parent snakes, especially the father. that will help more than actually breeding it. it looks quite normal to me, so if you breed it to a normal chances are you will just get 100% normals. i would just consider your female a normal, and then just breed multi-gene males to it. proving it out with a normal to most likely get a clutch of normals just doesnt seem to be worth it.
most likely scenario: the guy bred some codominant morph or combo to the female, like pewter male or yellowbelly male or whatever, and depending on the pairing and your luck you get something like 50% morph 50% normal. Or 25% normals and 75% with one or two genes. And yes, breeders just sort these out and sell them as normals and dont pay too much attention.
