Consanguineous Marriage
Consanguine marriage is marriage between individuals who are closely related. Though it may involve incest, it implies more than the sexual nature of incest. In a clinical sense, marriage between two family members who are second cousins or closer qualifies as consanguineous marriage. This is based on the gene copies their offspring may receive. Though these unions are still prevalent in some communities, as seen across the Greater Middle East region, many other populations have seen a great decline in intra-family marriages.Heidari F, Dastgiri S, Tajaddini N, et al.

Incest
Incest ( ) is sexual intercourse, sex between kinship, close relatives, for example a brother, sister, or parent. This typically includes sexual activity between people in consanguinity (blood relations), and sometimes those related by lineage (anthropology), lineage. It is condemned and considered immoral in many societies. It can lead to an increased risk of genetic disorders in children in case of pregnancy from incestuous sex. The incest taboo is one of the most widespread of all cultural taboos, both in present and in past societies. Most modern societies have laws regarding incest or social restrictions on closely consanguineous marriages. In societies where it is illegal, consensual adult incest is seen by some as a victimless crime. Some cultures extend the incest taboo to relatives with no consanguinity, such as Milk kinship, milk-siblings, stepsiblings, and adoptive siblings, albeit sometimes with less intensity. Third-degree relatives (such as half-aunt, half-nephew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fertility
Fertility in colloquial terms refers the ability to have offspring. In demographic contexts, fertility refers to the actual production of offspring, rather than the physical capability to reproduce, which is termed fecundity. The fertility rate is the average number of children born during an individual's lifetime. In medicine, fertility refers to the ability to have children, and infertility refers to difficulty in reproducing naturally. In general, infertility or subfertility in humans is defined as not being able to conceive a child after one year (or longer) of unprotected sex. The antithesis of ''fertility'' is infertility, while the antithesis of ''fecundity'' is sterility. Demography In demographic contexts, fertility refers to the actual production of offspring, rather than the physical capability to produce which is termed fecundity. While fertility can be measured, fecundity cannot be. Demographers measure the fertility rate in a variety of ways, which can be broa ...

Genealogy
Genealogy () is the study of families, family history, and the tracing of their lineages. Genealogists use oral interviews, historical records, genetic analysis, and other records to obtain information about a family and to demonstrate kinship and pedigrees of its members. The results are often displayed in charts or written as narratives. The field of family history is broader than genealogy, and covers not just lineage but also family and community history and biography. The record of genealogical work may be presented as a "genealogy", a "family history", or a " family tree". In the narrow sense, a "genealogy" or a " family tree" traces the descendants of one person, whereas a "family history" traces the ancestors of one person, but the terms are often used interchangeably. A family history may include additional biographical information, family traditions, and the like. The pursuit of family history and origins tends to be shaped by several motives, including the des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Types Of Marriage
The type, functions, and characteristics of marriage vary from culture to culture, and can change over time. In general there are two types: civil marriage and religious marriage, and typically marriages employ a combination of both (religious marriages must often be licensed and recognized by the state, and conversely civil marriages, while not sanctioned under religious law, are nevertheless respected). Marriages between people of differing religions are called interfaith marriages, while marital conversion, a more controversial concept than interfaith marriage, refers to the religious conversion of one partner to the other's religion for sake of satisfying a religious requirement. Americas and Europe In the Americas and Europe, in the 21st century, legally recognized marriages are formally presumed to be monogamous (although some pockets of society accept polygamy socially, if not legally, and some couples choose to enter into open marriages). In these countries, divorce i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xwedodah
Xwedodah ( ; Avestan: ) is a type of consanguine marriage historically practiced in Zoroastrianism before the Muslim conquest of Persia. Such marriages are recorded as having been inspired by Zoroastrian cosmogony and considered pious. It was a high act of worship in Zoroastrianism, and there were punishments for not performing it. This form of direct familial incest marriage allowed Zoroastrians to marry their sisters, daughters, granddaughters, and their own mothers to take as wives. Xwedodah was widely practiced by royalty and nobility, and possibly clergy, but it is not known if it was commonly practiced by families in other classes. In modern Zoroastrianism it is near non-existent, having been noted to have disappeared as an extant practice by the 11th century. Etymology While the Avestan term is still of ambiguous meaning and function in the Young Avestan texts, it is only later in Middle Persian that the term becomes used in its current form. The earliest use of the wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sibling Marriage
This article lists well-known individuals who had romantic or marital ties with their sibling(s) at any point in history. It does not include coupled siblings in works of fiction, although those from mythology and religion are included. Terminology 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''. In a heterosexual context, a female partner in such a relationship may be referred as a ''sister-wife''. A similar incestuous arrangement which is non-monogamous can be referred as ''sister-swapping'' or ''brother-swapping'', although this should not be confused with '' berdel'', which describes the situation in which families exchange brides or bridegrooms. History Sibling marriage was historically practiced among royalty in ancient through Ptolemaic Egypt, in the pre-Columbian Inca Empire of Peru, in pre-colonial Hawaiʻi, sporadicall ...

Laws Regarding Incest
Laws regarding incest (i.e. sexual activity between family members or close relatives) vary considerably between jurisdictions, and depend on the type of sexual activity and the nature of the family relationship of the parties involved, as well as the age and sex of the parties. Besides legal prohibitions, at least some forms of incest are also socially taboo or frowned upon in most cultures around the world. Incest laws may involve restrictions on marriage, which also vary between jurisdictions. When incest involves an adult and a child (under the age of consent) it is considered to be a form of child sexual abuse. Degrees of relationship Laws regarding incest are sometimes expressed in terms of degrees of relationship. The degree of relationship is calculated by adding the number of generations back to a closest common ancestor of each individual. Consanguinity (but not affinity) relationships may be summarized as follows: Most laws regarding prohibited degree of kinship c ...

Coefficient Of Relationship
The coefficient of relationship is a measure of the degree of consanguinity (or biological relationship) between two individuals. The term coefficient of relationship was defined by Sewall Wright in 1922, and was derived from his definition of the coefficient of inbreeding of 1921. The measure is most commonly used in genetics and genealogy. A coefficient of inbreeding can be calculated for an individual, and is typically one-half the coefficient of relationship between the parents. In general, the higher the level of inbreeding the closer the coefficient of relationship between the parents approaches a value of 1, expressed as a percentage, and approaches a value of 0 for individuals with arbitrarily remote common ancestors. Coefficient of relationship The coefficient of relationship r between two people B and C is obtained by a summation of coefficients calculated for every line by which they are connected to their identical ancestors point, common ancestors. Each such line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cousin Marriage
A cousin marriage is a marriage where the spouses are cousins (i.e. people with common grandparents or people who share other fairly recent ancestors). The practice was common in earlier times and continues to be common in some societies today. In some jurisdictions such marriages are prohibited due to concerns about inbreeding. Worldwide, more than 10% of marriages are between first or second cousins. Cousin marriage is an important topic in anthropology and alliance theory. In some cultures and communities, cousin marriages are considered ideal and are actively encouraged and expected; in others, they are seen as incestuous and are subject to social stigma and taboo. Other societies may take a neutral view of the practice, neither encouraging nor condemning it, though it is usually not considered the norm. Cousin marriage was historically practiced by indigenous cultures in Indigenous Australians, Australia, Indigenous peoples of the Americas#North America, North America, Indig ...

Avunculate Marriage
An avunculate marriage (or uncle/aunt-niece/nephew marriage) is a marriage with a parent's sibling or with one's sibling's child—i.e., between an uncle or aunt and their niece or nephew. Such a marriage may occur between biological (consanguine) relatives or between persons related by marriage ( affinity). In some countries, avunculate marriages are prohibited by law, while in others marriages between such biological relatives are both legal and common, though now far less common. If the partners in an avunculate marriage are biologically related, they normally have the same genetic relationship as half-siblings, or a grandparent and grandchild—that is they share approximately 25% of their genetic material. (They are therefore more closely related than partners in a marriage between first cousins or between granduncle/grandaunt and grandniece/grandnephew, in which on average the members share 12.5% of inherited genetic material, but less than that of a marriage between, ...
