Endogamy
Endogamy is the practice of marrying within a specific social group, religious denomination, caste, or ethnic group, rejecting those from others as unsuitable for marriage or other close personal relationships. Endogamy is common in many cultures and ethnic groups. Several religious and ethnic religious groups are traditionally more endogamous, although sometimes with the added dimension of requiring marital religious conversion. This permits an exogamous marriage, as the convert, by accepting the partner's religion, becomes accepted within the endogamous rules. Endogamy, as distinct from consanguinity, may result in transmission of genetic disorders, the so-called founder effect, within the relatively closed community. Adherence Endogamy can serve as a form of self-segregation; a community can use it to resist integrating and completely merging with surrounding populations. Minorities can use it to stay ethnically homogeneous over a long time as distinct communities within ... [...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, though in some jurisdictions such marriages are prohibited. 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. Cousin marriage was historically practiced by indigenous cultures in Indigenous Australians, Australia, Indigenous peoples of the Americas#North America, North America, Indigenous peoples of the Americas#South America, South America, and Polynesians, Polynesia. In some jurisdictions, cousin marriage is Prohibited degree of kinship, lega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auto-segregation
Auto-segregation or self-segregation is the separation of a religious, ethnic or racial group from other groups in a country by the group itself naturally. This usually results in decreased social interactions between different ethnic, racial or religious groups and can be classed as a form of social exclusion. Through self-segregation, the members of the separate group can establish their own services, and maintain their own traditions and customs. For example, some of the world's uncontacted peoples have preferred not to interact with the rest of the globally integrated human population. By remaining in a reserve and in isolation, they can preserve their cultures intact as long as they choose and the surrounding states protect them. A modern form of self-segregation occurring in prominent Western countries for example is influenced by White demographic decline however this is not the only example and can also be found in heterogeneous ethnically and religiously diverse countri ...

Caste
Caste is a form of social stratification characterised by endogamy, hereditary transmission of a style of life which often includes an occupation, ritual status in a hierarchy, and customary social interaction and exclusion based on cultural notions of purity and pollution. * Quote: "caste ort., casta=basket ranked groups based on heredity within rigid systems of social stratification, especially those that constitute Hindu India. Some scholars, in fact, deny that true caste systems are found outside India. The caste is a closed group whose members are severely restricted in their choice of occupation and degree of social participation. Marriage outside the caste is prohibited. Social status is determined by the caste of one's birth and may only rarely be transcended." * Quote: "caste, any of the ranked, hereditary, endogamous social groups, often linked with occupation, that together constitute traditional societies in South Asia, particularly among Hindus in India.

Consanguinity
Consanguinity ("blood relation", from Latin '' consanguinitas'') is the characteristic of having a kinship with another person (being descended from a common ancestor). Many jurisdictions have laws prohibiting people who are related by blood from marrying or having sexual relations with each other. The degree of consanguinity that gives rise to this prohibition varies from place to place. Such rules are also used to determine heirs of an estate according to statutes that govern intestate succession, which also vary from jurisdiction to jurisdiction. In some places and time periods, cousin marriage is allowed or even encouraged; in others, it is taboo, and considered to be incest. The degree of relative consanguinity can be illustrated with a ''consanguinity table'' in which each level of lineal consanguinity (''generation'' or '' meiosis'') appears as a row, and individuals with a collaterally consanguineous relationship share the same row. The Knot System is a numerical not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethnic Religion
In religious studies, an ethnic religion is a religion or belief associated with a particular ethnic group. Ethnic religions are often distinguished from universal religions, such as Christianity or Islam, in which gaining converts is a primary objective and, therefore, are not limited in ethnic, national or racial scope. Terminology A number of alternative terms have been used instead of ''ethnic religion''. Another term that is often used is '' folk religion''. While ''ethnic religion'' and ''folk religion'' have overlapping uses, the latter term implies "the appropriation of religious beliefs and practices at a popular level." The term ''folk religion'' can therefore be used to speak of certain Chinese and African religions, but can also refer to popular expressions of more multi-national and institutionalized religions such as Folk Christianity or Folk Islam. In Western contexts, a variety of terms are also employed. In the United States and Canada a popular alternat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marital Conversion
Marital conversion is religious conversion upon marriage, either as a conciliatory act, or a mandated requirement according to a particular religious belief. Endogamous religious cultures may have certain opposition to interfaith marriage and ethnic assimilation, and may assert prohibitions against the conversion ("marrying out") of one their own claimed adherents. Conversely, they may require the marital conversion of those who wish to marry one of their adherents. Christianity Catholicism Historically, in the case of the Catholic Church, Catholics were obligated to marry only other Catholics (including those of the Eastern Rite), and marital conversion of the non-Catholic party was considered almost obligatory. However, it was permissible for a Catholic to marry an Independent/ Old Catholic (who is not in communion with Rome) or non-Catholic baptized in a manner recognized by the Catholic Church as valid (i.e., mainline Christians such as Episcopalians or Lutherans, and Ea ...

Exogamy
Exogamy is the social norm of marrying outside one's social group. The group defines the scope and extent of exogamy, and the rules and enforcement mechanisms that ensure its continuity. One form of exogamy is dual exogamy, in which two groups continually intermarry with each other. In social science, exogamy is viewed as a combination of two related aspects: biological and cultural. Biological exogamy is marriage of nonblood-related beings, regulated by forms of incest law. Cultural exogamy is marrying outside a specific cultural group; the opposite being endogamy, marriage within a social group. Biology of exogamy Exogamy often results in two individuals that are not closely genetically related marrying each other; that is, outbreeding as opposed to inbreeding. In moderation, this benefits the offspring as it reduces the risk of the offspring inheriting two copies of a defective gene. Increasing the genetic diversity of the offspring improves the chances of offspring reprod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedigree Collapse
In genealogy, pedigree collapse describes how reproduction between two individuals who share an ancestor causes the number of distinct ancestors in the family tree of their offspring to be smaller than it could otherwise be. Robert C. Gunderson coined the term; synonyms include implex and the German ''Ahnenschwund'' (loosely translated: "loss of lineage"). Overview Without pedigree collapse, a person's ancestor tree is a binary tree, formed by the person, the parents (2), the grandparents (4), great-grandparents (8), and so on. However, the number of individuals in such a tree grows exponentially and will eventually become impossibly high. For example, a single individual alive today would, over 30 generations going back to the High Middle Ages, have 230 or roughly 1,000 million ancestors, more than the total world population at the time. This paradox is explained by shared ancestors, referred to as pedigree collapse. Instead of consisting of all different individuals, a tree ...

Double Cousin
Most generally, in the lineal kinship system used in the English-speaking world, a cousin is a type of familial relationship in which two relatives are two or more familial generations away from their most recent common ancestor. Commonly, "cousin" refers to a first cousin – a relative of the same generation whose most recent common ancestor with the subject is a grandparent. Degrees and removals are separate measures used to more precisely describe the relationship between cousins. ''Degree'' measures the separation, in generations, from the most recent common ancestor(s) to a parent of one of the cousins (whichever is closest), while ''removal'' measures the difference in generations between the cousins themselves, relative to their most recent common ancestor(s). To illustrate usage, a second cousin is a cousin with a ''degree'' of two; there are three (not two) generations from the common ancestor(s). When the degree is not specified, first cousin is assumed. A cousi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sibling Marriage
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 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 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 leg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inbreeding
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from incestuous sexual relationships and consanguinity. Animals avoid incest only rarely. Inbreeding results in homozygosity, which can increase the chances of offspring being affected by recessive traits. In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce. An individual who inherits such deleterious traits is colloquially referred to as ''inbred''. The avoidance of expression of such deleterious recessive alleles caused by inbreeding, via inbreeding avoidance mechanisms, is the main selective reason for outcros ...

Social Group
In the social sciences, a social group can be defined as two or more people who interact with one another, share similar characteristics, and collectively have a sense of unity. Regardless, social groups come in a myriad of sizes and varieties. For example, a society can be viewed as a large social group. The system of behaviors and psychological processes occurring within a social group or between social groups is known as group dynamics. Definition Social cohesion approach A social group exhibits some degree of social cohesion and is more than a simple collection or aggregate of individuals, such as people waiting at a bus stop, or people waiting in a line. Characteristics shared by members of a group may include Interest (emotion), interests, Value (personal and cultural), values, Social representation, representations, ethnic or social background, and kinship ties. Kinship ties being a social bond based on common ancestry, marriage or adoption. In a similar vein, some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
