First-degree Relatives

	First-degree Relatives A first-degree relative (FDR) is a person's parent (father or mother), full sibling (brother or sister) or child. It constitutes a category of family members that largely overlaps with the term nuclear family, but without spouses. If the persons are related by blood, the first degree relatives share approximately 50% of their genes. First-degree relatives are a common measure used to diagnose risks for common diseases by analyzing family history.

picture info	Nuclear Family A nuclear family, elementary family, cereal-packet family or conjugal family is a family group consisting of parents and their children (one or more), typically living in one home residence. It is in contrast to a single-parent family, the larger extended family, or a family with more than two parents. Nuclear families typically center on a heterosexual married couple which may have any number of children. There are differences in definition among observers. Some definitions allow only biological children that are full-blood siblings and consider adopted or half and step siblings a part of the immediate family, but others allow for a step-parent and any mix of dependent children, including stepchildren and adopted children. Some sociologists and anthropologists consider the nuclear family as the most basic form of social organization, while others consider the extended family structure to be the most common family structure in most cultures and at most times.

picture info	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.

	Third-degree Relative Third-degree relatives are a segment of the extended family and includes first cousins, great grandparents and great grandchildren. Third-degree relatives are generally defined by the expected amount of genetic overlap that exists between two people, with the third-degree relatives of an individual sharing approximately 12.5% of their genes. The category includes great-grandparents, great-grandchildren, grand-uncles, grand-aunts, first cousins, half-uncles, half-aunts, half-nieces and half-nephews.

picture info	Family Family (from la, familia) is a Social group, group of people related either by consanguinity (by recognized birth) or Affinity (law), affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its members and of society. Ideally, families offer predictability, structure, and safety as members mature and learn to participate in the community. Historically, most human societies use family as the primary locus of Attachment theory, attachment, nurturance, and socialization. Anthropologists classify most family organizations as Matrifocal family, matrifocal (a mother and her children), patrifocal (a father and his children), wikt:conjugal, conjugal (a wife, her husband, and children, also called the nuclear family), avuncular (a man, his sister, and her children), or Extended family, extended (in addition to parents and children, may include grandparents, aunts, uncles, or cousins).

	Next Of Kin A person's next of kin (NOK) are that person's closest living blood relatives. Some countries, such as the United States, have a legal definition of "next of kin". In other countries, such as the United Kingdom, "next of kin" may have no legal definition and may not necessarily refer to blood relatives at all. In some legal systems, rights regarding inheritance (which imply a decision-making capacity — for example, in a medical emergency — where no clear will or instructions have been given, and where the person has no spouse) flow to the closest relative (regardless of the age, with a representative appointed if a minor), usually a child, a parent or a sibling. However, there are people without any close adult relatives and, in such a case, decision-making power often flows to a niece or nephew, first cousin, aunt or uncle, or grandparent. For example, if a person dies intestate, the laws of some jurisdictions require distribution of the estate to the decedent's spouse or c ...
