Genetic sexual attraction 550948 225925553 2008-07-16T01:22:16Z 71.123.221.37 /* TV */ Fixed an erroneous link {{POV|date=March 2008}} {{Refimprove|date=January 2008}} {{Cleanup|date=January 2008}} '''Genetic sexual attraction''' ('''GSA''') is [[sexual attraction]] between close relatives, such as brother and sister, who first meet as adults.{{Fact|date=June 2007}} The effect is also seen between [[cousin couple|cousins]].{{Fact|date=June 2007}} GSA may occur as a consequence of [[adoption]], when the adopted children knowingly or unknowingly encounter biological relatives. Although this is a rare consequence of adoptive reunions, the large number of adoptive reunions in recent years means that a larger number of people are affected.{{Fact|date=February 2007}} It is generally highly distressing to both parties, as this sexual attraction is contrary to their socialized sexual and moral structures (the [[incest taboo]]). When children are raised together in early childhood, this effect is reversed by a form of imprinting known as the [[Imprinting (psychology)#Westermarck effect|Westermarck effect]], which results in reduced sexual desire between the siblings; examples exist in Israeli [[kibbutz]]im and, formerly, in Chinese [[arranged marriage]]s known as [[Shim-pua marriage|Shim-pua]]. == Contributing factors == Several factors may contribute to GSA. People commonly rank faces similar to their own as more attractive, trustworthy, etc. than average. {{Fact|date=February 2007}} [[Heredity]] produces substantial physical similarity between close relatives. However, Bereczkei (2004) attributes this in part to childhood [[imprinting]] on the opposite-sex parent. Shared interests and personality traits are commonly considered desirable in a partner. The [[heritability]] of these qualities is a matter of [[Nature versus nurture|great debate]]; to whatever extent they are heritable, they will tend to cluster in close relatives. In cases of parent-child attraction, the parent may recognize traits of their sometime mate in the child. Such reunions typically produce complex emotions in all involved. == In popular culture == The numerous versions of this phenomenon testify to how it resonates. === Legend === * The story of [[Oedipus]] in [[Greek mythology]] is perhaps the most famous example of genetic sexual attraction. * In [[Greek mythology]], one version of the story of [[Narcissus (mythology)|Narcissus]] has the young man fall in love with his twin sister. The more common version has him pining for love of his own reflection. Both versions emphasise the dangerous attraction of the similar. It would be wise to remember that Narcissus became love-struck only after the introduction of [[Cupid's dart]], a ruse concocted with the help of the nymph [[Echo (mythology)|Echo]], who could speak only what had been spoken to her. The plan was that Echo would present herself to Narcissus immediately after his being pierced by the dart, at which point he would regale her with his undying love with which she would ecstatically concur, repeating his words that were the expression of her own passion, thus fulfilling her heartfelt desire. The dart indeed found its mark, but instead of espying Echo, Narcissus' gaze fell upon his own reflection in a sylvan pool and he accordingly was smitten with himself, such that he could not leave his reflection and wasted away on the bank to the point of death when the Gods took pity on him and changed him into a flower, that to this day gazes at its own reflected image. * In the [[medieval legends]] of [[King Arthur]], collected by Sir [[Thomas Malory]] under the title ''[[Le Morte d'Arthur]]'' and retold in the 20th century by [[T. H. White]] as ''[[The Once and Future King]]'', King Arthur is seduced by his half-sister [[Morgause]], who subsequently gives birth to [[Mordred]]. This is one of the key elements in Arthur's downfall. * In [[Wagner]]'s opera ''[[Die Walküre]]'', based on the [[Norse mythology|Norse myth]], twin brother and sister Siegmund and Sieglinde meet as adults and fall in love; Sieglinde later gives birth to a son, [[Sigurd|Siegfried]]. This tale influenced "The Blood of the Volsungs", a 1905 short story by [[Thomas Mann]] that concerns the relationship between a brother and sister. * In [[Finnish mythology]], [[Kullervo]] unknowingly seduces a beggar-girl who is his sister. When the girl finds out Kullervo is her brother, she commits suicide. * In [[Pandosto]], the source of [[Shakespeare]]'s [[The Winter's Tale]], the titular character falls in love with his estranged daughter, [[Fawnia]]. === Theatre === * In [[Gotthold Ephraim Lessing]]'s 18th century ''Nathan the Wise'', Nathan's adopted daughter Rachel is rescued from a house fire by a passing [[knight templar]]. They immediately fall in love - only to find out that they are brother and sister. This is, however, revealed before their relationship develops significantly. * In [[John Ford (dramatist)|John Ford]]'s play ''[['Tis Pity She's a Whore]]'' a passionate sexual relationship develops between the siblings Giovanni and Annabella resulting in Annabella's pregnancy. The play concludes in a bloodbath of revenge and passion, and is considered one of the most controversial works in English literature. === Books === * [[Kathryn Harrison]]'s memoir ''[[The Kiss]]'' reveals the details of an affair she had with her father after meeting reuniting with him during her college years. * [[Vladimir Nabokov]]'s novel ''[[Ada or Ardor: A Family Chronicle]]'' recounts the incestuous life-long romance of Van and his sister Ada, who initially think they are cousins. * In [[Arundhati Roy]]'s [[Booker Prize]] winning novel ''[[The God of Small Things]]'', Estha (male) and Rahel (female) are twins who are separated at a young age, then reunite as adults, when (pp 310-311) "...they broke the Love Laws. That lay down who should be loved." * In [[Jeffrey Eugenides]]' [[Pulitzer Prize]] winning novel ''[[Middlesex (novel)|Middlesex]]'', a brother and sister move from Greece to the U.S. in the 1920s and start a family. Later in the novel their son marries his second cousin. *In [[J. R. R. Tolkien]]'s ''[[The Children of Húrin]]'' the main character ([[Túrin]]) falls in love with his estranged sister ([[Nienor]]), who had been bewitched by a dragon (Glaurung) to forget her past. Neither recognizes the other due to early separation. * In [[Robert A. Heinlein]]'s novel ''[[Time Enough for Love]]'', a pair of twins who allegedly share no genetic material marry and have children, then have to be talked out of letting their children marry each other. * In [[J. V. Jones]]'s trilogy ''[[The Book of Words]]'', Jack, the boy of the prophecy, discovers that he was in love with his half-sister, also a bastard of the late king. * In [[V. C. Andrews]]'s ''[[V. C. Andrews#Novels|Dollanganger series]]'', two children, Cathy and Christopher, end up being sexually attracted to each other and engage in sexual activity. This is due, in part, to their seclusion from the outside world. They, in turn, were the production of inbreeding. *In [[Cassandra Clare]]'s novel ''[[City of Bones (Cassandra Clare novel)|City of Bones]]'', main characters Clary and Jace are romantically attracted to each other. At the end of the book they are revealed to be full siblings. * In Patrick Augustus's ground-breaking novel about [[Black British]] men, ''[[Babyfather]]'' (1994), one of the marriages the narrative is working towards is put on hold when a character is told by his father that his fiancee is really his half-sister. * In [[Beryl Bainbridge]]'s novel ''An Awfully Big Adventure'', a man has a [[one-night stand]] with an underaged girl he later learns was his daughter. * In [[Caroline Graham]]'s first novel in the Chief Inspector Barnaby series, ''The Killings at Badger's Drift'', the motive for the murders is the desire of siblings Michael and Katherine Lacey to hide their incestuous relationship.

They have sexual intercourse quite often for several months and Emmeline gets pregnant. * In the 1996 movie ''[[Lone Star (1996 film)|Lone Star]]'', the instant and deep attraction which Sam Deeds and Pilar Cruz feel towards each other is ultimately connected to the fact that they are unknowingly half-siblings. Despite this they decide to continue their relationship. This matter has large metaphorical significance with regards to the primary theme of the movie, race relations in the small town. * In the 1985 movie ''[[Back to the Future]]'', the main character, [[Marty McFly]], goes back in time and accidentally meets his mother when she is a [[teenager]], who is very attracted to him until they kiss, at which point she compares it to kissing her brother. * In the original ''[[Star Wars]]'' movies, [[Luke Skywalker]] and his twin sister, [[Princess Leia Organa]], who meet as adults not knowing their connection, arguably experience a form of GSA, although primarily on Luke's part.

After telling Anna that he was adopted, she encouraged his search for his birth parents, only to discover his mother was Anna's mother. This revelation caused both characters great suffering and virtually destroyed Anna's relationship with her/their mother, but her feelings had grown so strong for Merlin that she continued it, eventually getting pregnant. The baby was never born, however, as she was involved in a train crash at the start of the following series, and after first having both legs amputated, she eventually died of her injuries. The characters of Merlin and his/Anna's mother did not continue after her death. * In the episode of ''[[My Name Is Earl]]'' in which Joy's marriage to "crabman" is revealed to her parents, Joy's father explains that he is not a racist, but that he objected to Joy dating a black boy in high school because she was his half-sister. * In the ''[[House (TV series)|House, M.D.]]'' episode "[[Fools for Love]]", House treats a married couple whose uncannily similar symptoms suggest shared exposure to an environmental factor, but they turn out to be half-[[sibling]]s suffering from the same rare genetic disorder. * In the ''[[Futurama]]'' episode "[[Roswell That Ends Well]]", [[Philip J Fry|Fry]], who goes back in time, has sex with his grandmother after the death of the man he presumed to be his grandfather, and [[Grandfather Paradox|becomes his own grandfather]]. * In ''[[The Simpsons]]'', in the episode "[[The Regina Monologues]]", [[Homer Simpson]] meets his half-sister Abbie- conceived during [[Abe Simpson|Grampa]]'s time in Britain during the [[Second World War]]- for the first time and seems to display a sexual attraction to her, despite, or maybe because of, the fact that Abbie looks very much like a female version of himself. * In [[BBC]] mystery drama ''[[Jonathan Creek]]'', the Christmas special "''Black Snow''" features a young man being manipulated into killing a famous actress he was in love with, Jonathan Creek later deducing that the man was actually the actress's long-lost son, given up for adoption years ago. * In an episode of ''[[That '70s Show]]'', Eric finds himself attracted to his visiting cousin. * In an episode of ''[[Friends]]'', [[Ross Geller]] becomes smitten with his and [[Monica Geller|Monica]]'s gorgeous blonde cousin.

Despite this revelation she still wants to get in his pants. * In an episode of ''[[Aliens in America]]'' titled "Purple Heart", the kids in school think Justin Tolchuck wants to sleep with his older sister because, to cheer her up after a very nasty breakup, he gives her a special school-sponsored Valentine that usually only couples exchange. After a particularly loud (and coupley-sounding) public argument the two make up and even dance a little together. One of the popular girls muses that perhaps the Tolchuck siblings "really are dating". Her friend then feels free to confess that she "hooked up" with her cousin recently. The other girl looks repulsed. * In an episode of ''[[King of the Hill]]'' [[Bill Dauterive]] begins dating a young single mother of two.

They started to see other people but eventually gave in to their love for each other. They ran away with each other but whilst driving away from Hollyoaks Beth died in a car crash, Rhys managed to survive but was left devastated.

One of [[Superman]]'s ancestors was involved in a massive controversy when she broke the law by bringing one of her own clones to full sentience and attempting to get her unwitting son to marry it. This double taboo-breaking added was the trigger for a gathering civil war over clone rights which would eventually decimate the planet for generations. * In the manga [[Ayashi no Ceres]] (English title [[Ceres, Celestial Legend]]) by [[Yuu Watase]], twins Aki Mikage and Aya Mikage share a somewhat incestuous relationship once their 16th birthday passes and they both awaken the personalities of their past lives (Ceres for Aya and Mikage for Aki).

"They met later in life and felt an inevitable attraction, and the judge had to deal with the consequences of the marriage that they entered into and all the issues of their separation."<ref>[http://news.bbc.co.uk/1/hi/uk/7182817.stm "Parted-at-birth twins 'married'"], BBC News, [[11 January]] [[2008]].
