History Main / NoBloodTies

* ''''TabletopGame/{{Warhammer 40000}}'''': Tau pairings are decided by genetic matchups and the child is raised alongside the others of its caste. However, there is no stigma one way or the other, and there are some Tau who take an interest in their progeny's acheivements.

* The reptilian T'skrang of ''{{Earthdawn}}'' deposit their eggs in a communal creche, so knowing which hatchlings are your kids would require a lot of bookkeeping. They don't usually bother.

* In ''''TabletopGame/MagicTheGathering', on the Plane of Tarkir, there is the Dhromoka clan. All humanoids in the clan are raised communally, with no knowledge of who their parents are. This is likely to prevent ancestor worship, which was a large part of Dhromoka's predecessor the Abzan, but the leader of the current clan views as necromancy (since the spirits of the ancestors may be called upon in times of need). Nevertheless, some still practice the old ways in secret.

%%* ''The Dispossessed'' by Creator/UrsulaKLeGuin.
%%** Also Orgoreyn in ''The Left Hand of Darkness''.

* ''Film/LogansRun'' the "Utopian" future presented has everyone raised by surrogate robots until they come of age. A scene shows a room of infants before they're taken off to be raised elsewhere. One of the main characters even becomes severely annoyed that his friend even cares to wonder who his parents were.

* The cheela of Robert L. Forward's ''Dragon's Egg'' lay eggs, that are left in a clan hatchery to be tended by elderly cheela. They make no effort to keep track of which female lay which egg.

* Greil in [[VideoGame/FireEmblemTellius ''Fire Emblem: Path of Radiance'']] holds this view of his mercenaries: "In times like these, it matters not what our blood ties are. We are family. If you don't want to cause your family any grief, then live!" It doesn't stop him from raising Ike and Mist, and bequeathing command of the Greil Mercenaries to Ike, though.

* In Creator/OctaviaButler's Patternmaster 'verse, psychic parents ''cannot stand'' their own offspring, so all children are raised in boarding schools run by specialized psychics. They know who their parents are, but it's not important.

* ''The Dispossessed'' by UrsulaKLeGuin.
** Also Orgoreyn in ''The Left Hand of Darkness''.

* The Race from Harry Turtledove's ''WorldWar'' series work like this as a matter of necessity due to the fact that they have a mating season and lay eggs communally, so that not even the mothers know who their children are. An exception is made for the imperial family, as no females except the emperor's harem are allowed within his presence during the mating season to ensure that all his children can be accounted for (And he is the only one allowed to mate with them, to ensure that they're all his).

* In OctaviaButler's Patternmaster 'verse, psychic parents ''cannot stand'' their own offspring, so all children are raised in boarding schools run by specialized psychics. They know who their parents are, but it's not important.

* In ''Literature/HaloContactHarvest,'' it is mentioned that Sangheili are raised by maternal uncles instead of their actual fathers.

* The Charr race from ''GuildWars'' and ''GuildWars2'' live and breath this trope. Charr cubs only stay with their mothers for a very short period before being given over to Fahrars; educational camps where they will learn how to fight, unify and define their own social structures within their future warband, which are the only family that Charr have. Cubs have an awareness of their parents, but adults have no hand or interest in the training and growth of their offspring. Loyalty to the warband and the High Legion their warband belongs to supersedes any blood tie.

* The Qunari in the Franchise/DragonAge series do not associate mating with love and family as we understand it is a foreign concept. All children born into the Qun are raised by Tamassrans, the ruling female class responsible for the education of every child. When they reach 12 they are assigned their role in life based on the evaluation of their abilities. Breeding is also overseen by the Tamassrans, deciding which individuals mate for purely functional reasons. If two members of the Qun actually mate of their own accord and conceive a child, the parents are sent off for "reeducation" but the child is simply raised like any other. The Qunari waste nothing.

* AnneMcCaffrey is keen on this trope.
** Damia of the ''Talents'' series was fostered, sent away by her father when her mother couldn't keep track of her. While this isn't mandatory in this universe, it's certainly not frowned upon.

* In ''SaintBeast'', angels are described as being created through the love of God and have no man-woman distinction so blood relationships are impossible. They all grow up together in what is supposed to be a utopian community. Humans and gods, however, can reproduce normally resulting in the half-human half-angels Kira and Maya, sons of Lucifer, and [[spoiler:[[AmnesiacGod Luca]], Zeus' son.]]

* An extreme case is seen in ''The City And The Stars'' by Arthur C. Clark. In the city, Diaspar, new citizens are fabricated in near adult bodies by the Central Computer and then rather casually nurtured for twenty years by a randomly chosen 'Father' and 'Mother'. The only such 'family' we see is Alvin's and while Eriston and Etania are invariably described as 'kindly nonentities' Alvin clearly has a genuine affection for them and they apparently stand by him even though he's turned their world upside down.

**** What did you expect? It's {{Greg Weisman}}.

* The Green Martians in the first ''{{Barsoom}}'' book have their eggs taken by the elders, who chose the best to live. When they hatch, a randomly selected foster mother teaches the child to speak and a few other skills. John Carter sees this as hideously evil and the cause of much of their coldness. One Green Martian was conceived and reared in secret by her mother and knowing who her father is; she is much kinder than the rest. John Carter eventually reunites long suffering families after he leads the Green Martians in their conquest of the Red Martians.

* ''Warhammer40K'': Tau pairings are decided by genetic matchups and the child is raised alongside the others of its caste. However, there is no stigma one way or the other, and there are some Tau who take an interest in their progeny's acheivements.
* In MagicTheGathering, on the Plane of Tarkir, there is the Dhromoka clan. All humanoids in the clan are raised communally, with no knowledge of who their parents are. This is likely to prevent ancestor worship, which was a large part of Dhromoka's predecessor the Abzan, but the leader of the current clan views as necromancy (since the spirits of the ancestors may be called upon in times of need). Nevertheless, some still practice the old ways in secret.

* On ''InvaderZim,'' Irkens are grown in jars and enter training immediately after "birth." They nevertheless seem to have familial feelings, since Zim considers the "cold, unfeeling robot arm" that activated him as his parent.

* The Trolls in ''{{Homestuck}}'' never meet their parents. Genetic material is collected and grown in the eggs of a giant insect, and once the young Trolls grow out of the larval stage they are selected by a monster that they share the colour of their blood with. This monster becomes their 'Lusus Naturae' and [[RaisedByWolves raises them into adulthood]]. They can try to track down other Trolls that they share genes with by finding who had a matching sign, if they choose.

* In ''{{Halo}}: Contact Harvest,'' it is mentioned that Sangheili are raised by maternal uncles instead of their actual fathers.

** The ''DragonridersOfPern'' use it to an even greater degree. F'nor remarks to himself that Manora "was only his mother" and gets annoyed when she expresses any concern or affection for him. Lessa and F'lar foster their son, Felessan (later F'lessan) and, after the young man is seriously injured, Lessa remarks that she was never particularly maternal. Manora reassures her that the work she did as Weyrwoman was more important than looking after her son, especially when the other women of the weyr were happy to do so. The Dragonriders' FreeLoveFuture is a major contributor to why there are no blood ties (although "Bloodlines" as a whole are considered very important as a mark of pedigree).

* In ''TheGiver'', babies are produced by women whose job title was [[ExactlyWhatItSaysOnTheTin Birthmother]] (though the matter of how exactly these babies are conceived is never addressed) but raised in 'family units' composed of a man and a woman ([[ArrangedMarriage matched up by the Elders]]), and one male and one female child.
** Given that everybody's sex drive is chemically inhibited (pills for "Stirrings"), it's safe to assume that the kids are fertilized ''in vitro.''

* In Octavia Butler's Patternmaster 'verse, psychic parents ''cannot stand'' their own offspring, so all children are raised in boarding schools run by specialized psychics. They know who their parents are, but it's not important.
