This article gives a list of individuals who have been romantically or maritally coupled with a sibling. This list does not include coupled siblings in fiction, although ones from mythology and religion are included.

Terminology [ edit ]

There are many terms used to describe a romantic bond between siblings, including formal nomenclature such as adelphogamy, specific hyponyms such twincest, or slang terms like sibcest.[2][3] In a heterosexual context, a female partner in such a relationship may be referred as a sister-wife.[4] A similar incestuous arrangement which is non-monogamous can be referred as sister-swapping or brother-swapping,[5] although this should not be confused with berdel, which describes the situation in which families exchange brides or bridegrooms.[6]

History [ edit ]

While cousin marriage is legal in most countries, and avunculate marriage is legal in several, sexual relations between siblings are considered incestuous almost universally. Sibling incest is legally prohibited in most countries worldwide. It was historically practiced in ancient Egypt and Inca tribes. Innate sexual aversion between siblings forms due to close association in childhood, in what is known as the Westermarck effect. Children who grow up together do not normally develop sexual attraction, even if they are unrelated, and conversely, siblings who were separated at a young age may develop sexual attraction. Thus, many cases of sibling incest, including accidental incest, concern siblings who were separated at birth or at a very young age.

Can a boy and a girl twin be identical?

Can male/female twins ever be identical?

In 99.9% of cases boy/girl twins are non-identical. However, in some extremely rare cases resulting from a genetic mutation, identical twins from an egg and sperm which began as male (XY) can develop into a male / female pair. This happens when the fertilised egg 'loses' one of the copies of the Y chromosome when it is dividing into two embryos in very early development. The resulting babies are then male (XY) and female (XO). The normal genetic make-up of a girl is XX. An XO baby is outwardly a girl, but her cells only have one copy of the X chromosome. This condition is called Turner Syndrome (more information on this, see the following link: Turner Syndrome).
