I don’t think anyone knows whether clones would have souls… or possibly, many not even very human has a soul… certainly some have lost touch with theirs.
And, what sort of clone do you mean? Some sci-fi clones are created from zygote cells like humans are. Others are created in a vat and somehow fast-aged… and some are created by duplication magic/technology that through one method or another duplicates the original… and Star Trek transporters supposedly disassemble and reassemble a person, and can sometimes make clones.
Since humans do not have a full understanding of souls/spirits/consciousness or agreement even on what a soul is, I don’t think we know the answer to this.
But to conjecture, I’d need more info on what you’re talking about.
For example, if you mean the type of clone where somehow you swap the original person’s DNA into a fertilized egg, and then let it grow like a normal test tube baby, I’d expect the soul to probably be more or less as if a child had been conceived naturally. But if you used some molecular duplication device to carbon copy an adult human, or fast-grow a new body with no life experience, I think those methods might tend to give you a soulless body.
