* In Literature/TheBible, Abraham and his descendants have mostly sons and few daughters for the first five generations. Out of Jacob's (his grandson) 70+ children and grandchildren, but only a single daughter (Dinah) and a single granddaughter (Serah) are named in The Book of Genesis.

Contrast BizarreAlienSexes and QueerAsTropes for scenarios where ''more'' than two genders or sexes are involved.

A family or group that is known for producing only sons or daughters, sometimes over the course of multiple generations. The reasons may be magical in nature, unknown or examples of ArtisticLicenseBiology, and when there is an exception to this rule this individual tends to be important. However uncommon this trope to happen in RealLife, it's actually TruthInTelevision.

* ''Webcomic/KillSixBillionDemons'': The ImmortalRuler Solomon David has fathered [[https://killsixbilliondemons.com/comic/king-of-swords-1-3/ twenty-five generations]] of sons to [[{{Nepotism}} serve as his councilors]]. The imbalance isn't addressed or explained, but his story arc [[spoiler:which shoes that he was once a normal man whose wife and daughters were killed by a lesser demiurge]] does make clear that he blinds himself to his own biases and the flaws in his "Law of Kings".

* In ''LightNovel/HeavyObject'', Major Frolaytia uses her military career to avoid being forced into an ArrangedMarriage by her family. Women of her family are desirable brides because of a "special ability" that any children they have are almost always male.

* In ''Manga/TwinStarExorcists'' for the last thousand years, Abe no Seimei's children are all male, [[spoiler:since they are spawned from [[HistoricalGenderFlip her]] yang energy, while the female one is born within her rival Doman Ashiya's bloodline.]]

* In ''{{ComicBook/Fables}}'' Snow and Rose's family had a generational trait that meant they only had girls. Their mother Lauda was the youngest of thirteen sisters. Unfortunately [[spoiler:A family curse compelled them to make it so ThereCanBeOnlyOne daughter who inherited the family’s magic, resulting in [[CainAndAbel them all trying to kill each other]].]]

* ''Webcomic/KillSixBillionDemons'': The ImmortalRuler Solomon David has fathered [[https://killsixbilliondemons.com/comic/king-of-swords-1-3/ twenty-five generations]] of sons to [[{{Nepotism}} serve as his councilors]]. The imbalance isn't addressed or explained, but his story arc does make clear that he blinds himself to his own biases and the flaws in his "Law of Kings".

* In the ''VideoGame/DragonAge'' series, [[CrystalDragonJesus Andraste]] only gave birth to two daughters during her lifetime (her sons were actually her stepsons through her husband's concubine) and one of her daughters herself only had girls. The Chantry believes Andraste's lineage has only produced girls since then, but this may just be propaganda to justify keeping the Orlesian Chantry led by women and automatically disqualify any man who claims descent from her from claiming a leadership role. Notably, any actual proof of who her descendants are was lost due to a combination of Tevinter society being patriarchal and patrilineal (which is why their Divine is a man), records being lost during the second Blight, and Andraste being so enraged that one of her daughters married a Tevinter magister that she destroyed the records herself.

* In the ''Manga/RanmaOneHalf'' second NonSerialMovie ''Nihao My Concubine'' revolves around the TravelingLandmass Togenkyo, an island which houses a magical spring that turns any living creature touched by its water into a human man, regardless of its original [[GenderBender sex]] or [[HumanityEnsues species]]. The problem is that this spring contaminates the other water sources on the island, and as a result, women who reside their can only give birth to male children. Consequently, Togenkyo is forced to raid ships and islands, kidnapping a fresh supply of new women to become spouses for the male residents and ensure the population survives.

* ''Anime/RanmaOneHalf'' during the movie ''Nihao My Concubine'' it's revealed the the influence of the floating island Togenkyou causes only male children to be born, which is why every so often, raiding parties are sent out to collect women from neighboring islands, to keep the population going.

Compare SingleLineOfDescent, which has a series of only children that are usually all male due to LineageComesFromTheFather, and OutnumberedSibling, where one sibling out of a group is the opposite sex of the others. Contrast with OneGenderRace, when a species simply doesn't have any members of a different sex. Recurrent instances of this may result in GenderRarityValue.

* In ''Manga/YuYuHakusho'' the Ice Maidens reproduce via parthenogenesis and are all female. When Hiei, a male, is born after his mother became intimate with a fire demon he's thrown off their floating island to die, the fate of all male children before him, but he managed to survive.

* ''LightNovel/AscendanceOfABookworm'': Past a certain point of the story, the protagonist is being passed off as the formerly SentIntoHiding daughter of a noble family. The family in question seems to be extremely prone to producing boys, starting with the paternal grandfather:

* In ''{{Literature/Discworld}}'' female children are rare among the Nac Mac Feegle. These girls become Keldas, leaders of Nac Mac Feegle clans. The fact they're a lot smarter (and saner) than most of the men helps too.

* For the Ingalls family of ''Literature/LittleHouseOnThePrairie'' fame, no male child ever survived past infancy. This was true both in real life and in the TV series.

* PlayedForDrama to some extent in ''Literature/PrideAndPrejudice''. Mr and Mrs Bennet have five daughters but no sons. As a result, upon Mr Bennet's death his estate will be inherited by a cousin Mr Collins due to inheritance laws of the time period favoring men, and there's concern over what will happen to his daughters. Mrs Bennet is extremely keen they all make good marriages to secure their futures.
* ''Literature/PrincessesOfThePizzaParlor'': Only female [[OurWitchesAreDifferent witches]] are known, and they appear to just be magical humans, gaining witch status through inheritance, but whether witches can ''only'' have female children, or whether male children are just not noted, is unknown.

* In Literature/TheBible, Abraham and his descendants have mostly sons and few daughters for the first five generations. Out of Jacob's (his grandson) 70+ children and grandchildren, only a single daughter (Dinah) and a single granddaughter (Serah) are named in The Book of Genesis.

* ''VideoGame/{{X}}'': The reptilian Teladi discovered after being separated from their homeworld due to the PortalNetwork shifting that they can alternately reproduce by parthenogenesis: their eggs will always develop as female if unfertilized. This resulted in them effectively becoming a OneGenderRace even after they rediscovered their home planet and incorporated it into their {{corporatocracy}}.

* In ''{{Webcomic/Blindsprings}}'', prior to the Revolution the Llyn royal family of Aberwelle had only produced daughters, and none of them had any luck producing the next generation, either dying or being infertile. RoyalInbreeding was the likely cause for some of these issues, as most Orphic families were somewhat inbred to try and preserve their magic.

* Nine-Banded Armadillos nearly always have litters of four identical pups either all male or all female making them a naturally occurring example of this trope.

* ''Franchise/TheLegendOfZelda'': Children of the Gerudo tribe are almost invariably female. A single male Gerudo is born every hundred years and becomes their king. The games' customary BigBad, the SorcerousOverlord Ganondorf, was one such male child.
