It is about morals in the age of contraception.
Comment on If you have sex with a clone of yourself, is it incest?

Yes. Incest is primarily not about some moral, but about keeping a diversity in the DNA, so two identical DNAs would be hard no.

Identical twins wouldn’t make a baby either

By your standards sisters would be okay or an uncle with his nephew. Its totally up to you, if you want to fuck your mother as long as she is postmenopausal?
Idk dude. I’m kinda not with you on this.

Your head is full of interesting stuff you are definitely #not into*…

I have no idea how big scifi that is, I’ll leave that question to some real biologist.
Also realized that one edge case might be cloned hermaphrodite, not sure how common is functional hermaphroditism amongst humans.

There was a episode of Sliders that dealt with that. Quinn almost hooked up with his female self in other world. So it is possible also there was a movie that dealt with it as well called Predestination with Ethan Hawke that dealt with having sex and making a child with oneself. So sci fi has done it.

My point is - we know that cloning is real and possible today.
Is changing gender also (soon to be) possible, or is that something that will remain exclusive to scifi for forseeable future? I have not a slightest idea.
No one doubts that anything is possible in scifi, that is why there is that word fiction.

Heinlein’s “all you zombies” is an early version of this.
In terms of biology, it’s extremely rare for humans to have fully functioning sets of both reproductive systems. The reproductive physiology develops from the same parts so it either develops “male”, “female”, or (more common than people think) somewhere in between but not “both”. A clone may or may not even develop in the same way.
One other possibility, though also very rare. is near-identical twins. If twins have the same genetics (in other words, they’re identical twins) but have intersex conditions that result in different reproductive development it’s conceivable that they could reproduce with each other. It’s uncommon to be fertile incongruous with your genetics, though, so again: this would be extremely unlikely.
That said, in a sci-fi context there are some options. Biological hermaphroditism is possible in animals, though there aren’t any vertebrates on Earth, so conceivably an alien species could encounter this problem.
Advanced medicine could also build people a new reproductive system and implant it, giving them the counterpart they lacked.
Of course, in that case, advanced medicine may also be able to give you someone else’s reproductive genetics (ex, implanted sperm or eggs) and thus effectively sidestep the genetic problems. I’m imagining a particularly narcissistic person getting a gender-flipped clone of themself and using someone else’s genetic material to have a kid with themself but also avoid the shallow gene pool problem.
Of course, you don’t need to go that far. If you’re female (or have those parts anyway) you can just do IVF. Don’t even need to clone yourself, then.
Anyway, this is getting a little silly.

Yeah, aren’t there occasional cases of have XY (male) and X0 (female, Turner’s syndrome) twins? That seems like the closest to OP’s scenario, and yes, it would definitely be incest.
