Ummmm dogs do not come in morphs they come in breeds... Each breed has been bred for extremely long times to come to the current day standards and were all bred because of the job they were meant to do. Ball python morphs are not different breeds at all they are naturally occurring genetic mutations. A black lab looks like that because someone wanted it to. A pastel looks as it does because a gene got screwed up. Now a lemon pastel, gratazani pastel, and all those other ones would be to ball pythons what the black lab is to dogs. Each is a different "line" or breed that looks as it does due to selective breeding.
