Pastel, Spider, and Mojave are all codominant morphs. So no matter which one you picked, you would have a 50% chance of producing more of the same.
IE, Mojave X Normal = 50% Normals and 50% Mojaves.
If a snake is 100% het for something, like Piebald, Albino, or Clown, that means they are guaranteed to carry one of these recessive genes. They are produced when one of the parents is a visible morph, such as an Albino X Het. Albino pairing.
If you bred a 100% Het and bred it to a normal you would produce 50% hets for that morph. Which, to me, are essentially just normals.
