Genetic sexual attraction (GSA) is sexual attraction between close relatives, such as brother and sister, who first meet as adults.^{[citation needed]} The effect is also seen between cousins.^{[citation needed]} Image File history File links Unbalanced_scales. ... In a species that reproduces sexually, sexual attraction is an attraction to other members of the same species for sexual or erotic activity. ... A cousin couple is a pair of cousins with a romantic or sexual relationship. ...

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.^{[citation needed]} It is generally highly distressing to both parties, as this sexual attraction is contrary to their socialized sexual and moral structures (the incest taboo). For other uses, see Adoption (disambiguation). ... The incest taboo refers to the cultural prohibition of sexual activity or marriage between persons defined as close relatives; the degree of which is determined by the society in which the persons live. ...

When children are raised together in early childhood, this effect is reversed by a form of imprinting known as the Westermarck effect, which results in reduced sexual desire between the siblings; examples exist in Israeli kibbutzim and, formerly, in Chinese arranged marriages known as Shim-pua. Imprinting is the term used in psychology and ethology to describe any kind of phase-sensitive learning (learning occurring at a particular age or a particular life stage) that is rapid and apparently independent of the consequences of behavior. ...

Contributing factors

Several factors may contribute to GSA. People commonly rank faces similar to their own as more attractive, trustworthy, etc. than average.^{[citation needed]} 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 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. The ancients had a variety of ideas about heredity: Theophrastus proposed that male flowers caused female flowers to ripen; Hippocrates speculated that seeds were produced by various body parts and transmitted to offspring at the time of conception, and Aristotle thought that male and female semen mixed at conception. ... Imprinting has different meanings in: Genetics: see imprinting (genetics) Psychology and ethology: see imprinting (psychology) In addition, the term imprint is used in publishing. ... In genetics, heritability is the proportion of phenotypic variation in a population that is attributable to genetic variation among individuals. ... The nature versus nurture debates concern the relative importance of an individuals innate qualities (nature) versus personal experiences (nurture) in determining or causing individual differences in physical and behavioral traits. ...

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 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, 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 myth, twin brother and sister Siegmund and Sieglinde meet as adults and fall in love; Sieglinde later gives birth to a son, 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.

Comics

• In The World of Krypton (vol. 2), John Byrne wrote of the planet Krypton's ancient past in which a culture of near-immortals thrived by storing sleeping clones of each citizen to harvest for replacement body parts as needed. 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). Aki, the aggressor, attempts to rape his twin at one point in the series while possessed with his family founder's spirit, Mikage.
• In the manga Angel Sanctuary by Kaori Yuki, the main characters, Setsuna Mudo and Sara Mudo, both share romantic feelings for each other despite being brother and sister. Like in Ayashi no Ceres, their affections are manifestations of feelings remaining from their past lives.
• In the manga and anime versions of Sailor Moon, created by Naoko Takeuchi, the character Chibi-Usa, who comes from the 31st century, shows love for Mamoru Chiba, who happens to be her future father.

In reality

• The BBC reported in January 2008 a speech by British peer Lord Alton, which referenced a case in which a judge had annulled the marriage of an unnamed couple, who had discovered that they were twins separated at birth and adopted separately. "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."^[1] However, no corroborating evidence has been provided for the story, which bears many of the hallmarks of an urban legend.^[2]

• The Australian reported in April 2008 about a father and daughter who allegedly met for the first time as adults and within two weeks had sex;^[3] and that same couple was reported to have had a daughter together by the Herald Sun.^[4] However, whether or not this is a genuine GSA situation is open to doubt as it has now been reported that this father and daughter had actually been in contact several times during the daughter's childhood when she stayed with her father and step-mother. They had also spent time together on a trip away from the step-mother on at least one occasion.^[5] This story was further reported on by 60 Minutes, with the two discussing their relationship publicly for the first time.^[6]

• In February 2007, there was a report that a brother and sister couple in Germany were fighting against anti-incest laws. They grew up separately, met as adults, and have had four children.^[7]
