Most people who have passed grade school know that men have one X and one Y chromosome while women have two X chromosomes. However, in Real Life it's not always that simple.
The whole issue of gender identity aside, anything that interferes with fetal development can cause various degrees of feminization or masculinization ranging from people who are genetically XY and physically female to people who are genetically XX and physically male to people who are intersex and whose anatomical sex is neither male nor female. There is also a phenomenon called chimerism which can cause different parts of the body to have different DNA, meaning DNA from someone's blood or saliva (the most common sources for DNA tests) may not match DNA from other parts of their bodies, which for fictional purposes usually means hair, skin or semen.
In fiction, this usually pops up in various kinds of detective stories and is used as an excuse to make a DNA test into a Red Herring. It can also be a source of drama or simply a character quirk. The actual cause is likely to be Hand Waved or just glossed over. Transgender people are covered by their own trope but may also fall under Wrong Genetic Sex if their transgender status is not known in advance and the plot hinges on the difference between their chromosomes and their appearance. Intersex people may also be included under similar circumstances. However, only individuals count: If an entire population is intersex, then it's a One-Gender Race.
See also Hermaphrodite, which may overlap but is in many cases a distinct phenomenon. Both "hermaphrodite" and "pseudohermaphrodite" were used as medical terms for these conditions in the past but that usage was not strictly accurate and is now considered pejorative.

In one episode of Law & Order: Special Victims Unit, the episode starts with a rapist getting killed by his victim and the DNA evidence leads the detectives to a teenage boy who just happens to have an ironclad alibi. It turns out his twin "sister" is actually his twin brother; it seems he lost his penis when they were circumcised as babies and the doctors who botched the operation covered their tracks by completing the job and talking his parents into raising him as a girl.
Sadly, this is actually Truth in Television: The episode is based on an actual case. Just like the character in the episode, the real man vehemently reverted to a male gender identity as soon as he got the chance. Sadly, he ended up killing himself instead of killing the doctor like his fictional counterpart in SVU did.

In The Day of Revolution, the supposedly male protagonist discovers in the first chapter that he is intersex and genetically female. Despite some misgivings and with a push from her parents she decides to reinvent herself as a girl. Hilarity Ensues.

In one episode of House, a woman turns out to be suffering from testicular cancer, due to Androgen insensitivity syndrome note In reality, androgen-insensitive women seldom have a significantly increased risk of testicular cancer; rather the "threat" of cancer is used as an excuse to remove the gender-incongruous gonads despite their being fundamentally harmless.

In one episode of Whose Line Is It Anyway?, during a game of Party Quirks, Colin was playing a character who suspected that people were not the gender they purported themselves to be and he spent his time during the game feeling up his fellow contestants.

In Faking It, Lauren's plot revolves around some pills she's taking and very defensive about. The rest of the main cast eventually finds out that she's intersex and androgen-insensitive.

Calliope (later Cal) from the book Middlesex was born intersex (genetically XY) and raised female until the age of fourteen. Notably, her being Raised as the Opposite Gender was completely unintentional on the part of both her doctors and her parents, since the doctor was nearsighted and had no idea that she was actually male.
Cal also meets a woman with Complete androgen insensitivity syndrome, an intersex condition that causes the woman affected to be born with a vagina, but with XY chromosomes, no uterus, and internal testes where the ovaries would typically be. Despite being able to pass as a woman, she strongly identifies herself as a hermaphrodite and is an intersex rights activist.

The original incarnation of Sadako of The Ring was this, thanks to androgen insenstivity. In the book, she was thrown into the well by a doctor who had raped her, and then found out she was intersex.

In Orphan Black, the genetic original person for both the female and male clone batches turns out to be the same person, an XX woman who had XY chromosomes in some of her cells due to chimerism.

This is a major plot point in an episode of Freaks and Geeks, when Ken's new girlfriend Amy tells her she's one of these. There was no DNA test or anything - the conflict came from Amy getting upset at Ken (who initially struggled with the revelation) telling his friends her big secret.

The character Ramona in Sticky Dilly Buns is defined to be a fairly classic case of 17-beta-Hydroxysteroid dehydrogenase III deficiency, a condition similar to androgen insensitivity syndrome (see below under Real Life). She's a well-adjusted heterosexual woman; the fact mainly serves to bemuse some of the other characters.
