I assume you would be refering to their color and pattern. There is no difference that I know of between the sexes. Also Welcome to the site If no one has told you yet.:salute:

That's not true what your freind told you they both carry unique traits that people breed for. Like if you have two ball pythons that are slightly banded you breed them together most of there babys will have bands but if you breed just a plain old ball with a banded you will get some that are banded and some that arent. With morphs though like say a pied if you breed it with a normal all you will get is are 50% Hetrozyogous for pied which means if you breed the baby back to the parent pied you would get pieds in your next clutch.
