* One ''ComicBook/JudgeDredd'' story set during a flashback to Chaos Day portrayed a group of cadets trying to survive. One of them is stated to be a Dredd clone. Falcone is the obvious, but wrong, candidate. Turns out the clone is female. [[spoiler:And pregnant.]]
* In ''ComicBook/DCComicsBombshells'', [[spoiler:Superman]] is an opposite-sex clone of [[spoiler:Supergirl]], created by [[spoiler:Hugo Strange]]. He also created a same-sex clone, who is that continuity's [[spoiler:Power Girl]].
* In the Marvel Graphic Novel #72, ''Fear Itself'', featuring Spider-Man and Silver Sable (released in 1992), Silver Sable is after a mysterious European personage named "The Baroness", a white woman with a large '80s blond hairdo. During the climactic confrontation, the Baroness reveals herself to be [[spoiler:the previous Baron Zemo, cloned by Arnim Zola into a female body, and the hairdo is a large blond wig. She then takes off the wig and puts on the mask Zemo's father wore during World War II]].
* In ''ComicBook/SpiderGwen'', ComicBook/TheFalcon is the teenage, male clone of ComicBook/CaptainAmerica, who is a black woman named Samantha Wilson in this continuity.
* Spider-Woman (who later went by Black Widow), in ''ComicBook/UltimateSpiderMan''. Ultimate Spider-Woman is a clone of Peter Parker, with all of his memories and personality traits - except she's considerably more abrasive, especially to Miles. (They were going to blank her memory and give her an entirely new made-up personality and set of memories, but didn't get around to it before wackiness ensued.)
* Used in a ''[[ComicBook/Supergirl1972 classic]]'' ''ComicBook/{{Supergirl}}'' comic where a criminal tries to clone Supergirl in order to use her twin to commit crimes. The (male) twin ends up committing suicide due to an Ethical Conflict between what his criminal creator has told him to do and what his twin wants him to do.
* After Fantomex of the ''[[ComicBook/XForce Uncanny X-force]]'' died, he was going to get a cloned body to come back with. However, he has three different brains and each brain received its own cloned body. The nicest brain got a female body called Cluster.
* ComicBook/{{X 23}} is an Opposite-Sex Clone of ComicBook/{{Wolverine}}, developed by Dr. Sarah Kinney as a solution to not being able to recreate a Y chromosome from a sample of Wolverine's DNA. So instead, she doubled the X chromosome.
* Also in Marvel, TheCollector (whose hobby with species is exactly what his name suggests) captured both ComicBook/HowardTheDuck and [[ComicBook/GuardiansOfTheGalaxy Rocket Raccoon]], and proceeded to create female clones of both, named Linda and Shocket, respectively...for [[ScrewYourself a breeding program]]. Both managed to survive and become their own individuals. (Incidentally, this suggests the Collector isn't as good at his job as he seems, since while there are only one of Howard's species in their universe, there ''is'' a female Halfworlder raccoon out there named Captain Sale.)
* ''ComicBook/WonderWoman1987'': Kreel biology means that attempting to clone a man may result in a female infant, as is the case for [[spoiler:the Emperor]].
* ''ComicBook/XCellent'' introduces Phatty, a female clone of Phat, one of the dead members of ''ComicBook/XStatix''.

Biologically, this is somewhat plausible for male-to-female cloning, because a male has an X-chromosome that can be doubled to produce a female clone, as in Garrett's poem and Heinlein's novel.[[note]]Strictly speaking, you don't even need the second X chromosome, though omitting it is a good way to kill 99% of your fetuses and give the surviving 1% [[https://en.wikipedia.org/wiki/Turner_syndrome Turner syndrome.]][[/note]] Alternatively, the SRY gene, which causes maleness, can be removed from the Y chromosome. For female-to-male cloning, the Y chromosome would have to come from another subject — most ideally the donor's father, as she would have inherited her father's Y chromosome had she been born male. Nevertheless, this would technically [[MixAndMatchMan not be a pure clone]]. A Y chromosome could be formed from one of the X-chromosomes, which would require absurd amounts of genetic engineering and amount to simple fiat anyway. Alternatively, the [[https://en.wikipedia.org/wiki/XX_male_syndrome SRY gene can be implanted in one of the X chromosomes]] to create a sterile clone that appears male. Somewhat fittingly when given the above, the majority of opposite-sex clones in fiction are female.

For female-to-male cloning, the Y chromosome would have to come from another subject, preferably a paternal relative and most ideally the father, as if the original subject were a male, she would have had a Y chromosome virtually identical to her father's.

See CloneAngst for when said clone is upset about their nature. Subtrope of ModifiedClone. Compare DistaffCounterpart, HalfIdenticalTwins and ScrewYourself. See also TransAudienceInterpretation, as that is a common fan explanation as to why this trope occurs.
