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 cou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parallel And Cross Cousins
In discussing consanguineal kinship in anthropology, a parallel cousin or ortho-cousin is a cousin from a parent's same-sex sibling, while a cross-cousin is from a parent's opposite-sex sibling. Thus, a parallel cousin is the child of the father's brother (paternal uncle's child) or of the mother's sister (maternal aunt's child), while a cross-cousin is the child of the mother's brother (maternal uncle's child) or of the father's sister (paternal aunt's child). Where there are unilineal descent groups in a society (i.e. matrilineal and/or patrilineal), one's parallel cousins on one or both sides will belong to one's own descent group, while cross-cousins will not (assuming descent group exogamy). Role The role of cross-cousins is especially important in some cultures. For example, marriage is promoted between them in the Iroquois system. Parallel cousins are occasionally the subject of promoted marriage, such as the preferential marriage of a male to his father's brother's ...

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 fo ...

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 n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grandparent
Grandparents, individually known as grandmother and grandfather, are the parents of a person's father or mother – paternal or maternal. Every sexually-reproducing living organism who is not a genetic chimera has a maximum of four genetic grandparents, eight genetic great-grandparents, sixteen genetic great-great-grandparents, thirty-two genetic great-great-great-grandparents, sixty-four genetic great-great-great-great grandparents, etc. In the history of modern humanity, around 30,000 years ago, the number of modern humans who lived to be a grandparent increased. It is not known for certain what spurred this increase in longevity but largely results in the improved medical technology and living standard, but it is generally believed that a key consequence of three generations being alive together was the preservation of information which could otherwise have been lost; an example of this important information might have been where to find water in times of drought.

Arranged Marriage
Arranged marriage is a type of marital union where the bride and groom are primarily selected by individuals other than the couple themselves, particularly by family members such as the parents. In some cultures a professional matchmaker may be used to find a spouse for a young person. Arranged marriages have historically been prominent in many cultures. The practice remains common in many regions, notably South Asia, the Middle East, North Africa, and the Caucasus. In many other parts of the world, the practice has declined substantially during the 19th and 20th centuries. Forced marriages, practiced in some families, are condemned by the United Nations. The specific sub-category of forced child marriage is especially condemned. In other cultures, people mostly choose their own partner. History Arranged marriages were very common throughout the world until the 18th century. Typically, marriages were arranged by parents, grandparents or other close relatives and trusted fri ...

Lineal Kinship
Eskimo kinship or Inuit kinship is a category of kinship used to define family organization in anthropology. Identified by Lewis Henry Morgan in his 1871 work ''Systems of Consanguinity and Affinity of the Human Family'', the Eskimo system was one of six major kinship systems (Eskimo, Hawaiian, Iroquois, Crow, Omaha, and Sudanese). The system of English-language kinship terms falls into the Eskimo type. Joint family The joint family system places no distinction between patrilineal and matrilineal relatives; instead, it focuses on differences in kinship distance (the closer the relative is, the more distinctions are made). The system emphasizes the nuclear family, identifying directly only the mother, father, brother, and sister. All other relatives are grouped together into categories. It uses both classificatory and descriptive terms, differentiating between gender, generation, lineal relatives (relatives in the direct line of descent), and collateral relatives (blo ...

Kinship
In anthropology, kinship is the web of social relationships that form an important part of the lives of all humans in all societies, although its exact meanings even within this discipline are often debated. Anthropologist Robin Fox says that the study of kinship is the study of what humans do with these basic facts of lifemating, gestation, parenthood, socialization, siblingship etc. Human society is unique, he argues, in that we are "working with the same raw material as exists in the animal world, but ecan conceptualize and categorize it to serve social ends." These social ends include the socialization of children and the formation of basic economic, political and religious groups. Kinship can refer both to the patterns of social relationships themselves, or it can refer to the study of the patterns of social relationships in one or more human cultures (i.e. kinship studies). Over its history, anthropology has developed a number of related concepts and terms in the study ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aunt
An aunt is a woman who is a sibling of a parent or married to a sibling of a parent. Aunts who are related by birth are second-degree relatives. Known alternate terms include auntie or aunty. Children in other cultures and families may refer to the cousins of their parents as aunt or uncle due to the age and generation gap. The word comes from la, amita via Old French ''ante'' and is a family relationship within an extended or immediate family. The male counterpart of an aunt is an uncle, and the reciprocal relationship is that of a nephew or niece. Additional terms * A half-aunt is a half-sister of a parent. * An aunt-in-law is the aunt of one's spouse and is the wife of the uncle of somebody. . * A great-aunt/grandaunt (sometimes written grand-aunt) is the sister of one's grandparent. Despite the popular usage of great-aunt, genealogists consider it more correct to use grandaunt for a grandparent's sister to avoid confusion with earlier generations. Similarly, the ...
