Siblings
A sibling is a relative that shares at least one parent with the other person. A male sibling is a brother, and a female sibling is a sister. A person with no siblings is an only child. While some circumstances can cause siblings to be raised separately (such as foster care or adoption), most societies have siblings grow up together. This causes the development of strong emotional bonds, with siblinghood considered a unique type of relationship. The emotional bond between siblings is often complicated and is influenced by factors such as parental treatment, birth order, personality, and personal experiences outside the family. Medically, a full-sibling is a first-degree relative and a half-sibling is a second-degree relative as they are related by 50% and 25%, respectively. Definitions The word ''sibling'' was reintroduced in 1903 in an article in '' Biometrika'', as a translation for the German ''Geschwister'', having not been used since Middle English, specifically 142 ...

Sperm Donation
Sperm donation is the provision by a man of his sperm with the intention that it be used in the artificial insemination or other "fertility treatment" of one or more women who are not his sexual partners in order that they may become pregnant by him. Where pregnancies go to full term, the sperm donor will be the biological father of every baby born from his donations. The man is known as a sperm donor and the sperm he provides is known as "donor sperm" because the intention is that the man will give up all legal rights to any child produced from his sperm, and will not be the legal father. Sperm donation may also be known as "semen donation". Sperm donation should be distinguished from "shared parenthood" where the male who provides the sperm used to conceive a baby agrees to participate in the child's upbringing. Where a sperm donor provides his sperm in order for it to be used to father a child for a woman with whom he has little or no further contact, it is a form of third part ...

Only Child
An only child is a person with no siblings, by birth or adoption. Overview Throughout history, only-children were relatively uncommon. From around the middle of the 20th century, birth rates and average family sizes fell sharply for a number of reasons, including perceived concerns about human overpopulation and more women having their first child later in life due to birth control and women in the workforce. The proportion of families in the United States with only-children increased during the Great Depression but fell during the Post–World War II baby boom. After the Korean War ended in 1953, the South Korean government suggested citizens each have one or two children to boost economic prosperity, which resulted in significantly reduced birth rates and a larger number of only-children in the country. From 1980 to 2015, the one-child policy in the People's Republic of China restricted most parents to having only one child, although it was subject to local relaxations and in ...

Birth Order
Birth order refers to the order a child is born in their family; firstborn, first-born and second-born are examples. Birth order is often believed to have a profound and lasting effect on psychological development. This assertion has been repeatedly challenged. Recent research has consistently found that earlier born children score slightly higher on average on measures of intelligence, but has found zero, or almost zero, robust effect of birth order on personality. Nevertheless, the notion that birth-order significantly influences personality continues to have a strong presence in pop psychology and popular culture. Theory Alfred Adler (1870–1937), an Austrian psychiatrist, and a contemporary of Sigmund Freud and Carl Jung, was one of the first theorists to suggest that birth order influences Personality psychology, personality. He argued that birth order can leave an indelible impression on an individual's style of life, which is one's habitual way of dealing with the tasks of ...

Sister
A sister is a woman or a girl who shares parents or a parent with another individual; a female sibling. The male counterpart is a brother. Although the term typically refers to a familial relationship, it is sometimes used endearingly to refer to non-familial relationships. A full sister is a first-degree relative. Overview The English word ''sister'' comes from Old Norse which itself derives from Proto-Germanic ''*swestēr'', both of which have the same meaning, i.e. sister. Some studies have found that sisters display more traits indicating jealousy around their siblings than their male counterparts, brothers. In some cultures, sisters are afforded a role of being under the protection by male siblings, especially older brothers, from issues ranging from bullies or sexual advances by womanizers. In some quarters, the term ''sister'' has gradually broadened its colloquial meaning to include individuals stipulating kinship. In response, in order to avoid equivocation, som ...

Twin
Twins are two offspring produced by the same pregnancy.MedicineNet > Definition of Twin Last Editorial Review: 19 June 2000 Twins can be either ''monozygotic'' ('identical'), meaning that they develop from one zygote, which splits and forms two embryos, or ''dizygotic'' ('non-identical' or 'fraternal'), meaning that each twin develops from a separate egg and each egg is fertilized by its own sperm cell. Since identical twins develop from one zygote, they will share the same sex, while fraternal twins may or may not. In very rare cases, fraternal or (semi-) identical twins can have the same mother and different fathers ( heteropaternal superfecundation). In contrast, a fetus that develops alone in the womb (the much more common case in humans) is called a ''singleton'', and the general term for one offspring of a multiple birth is a ''multiple''. Unrelated look-alikes whose resemblance parallels that of twins are referred to as doppelgänger. Statistics The human twin birth ...

Parent
A parent is either the progenitor of a child or, in humans, it can refer to a caregiver or legal guardian, generally called an adoptive parent or step-parent. Parents who are progenitors are First-degree relative, first-degree relatives and have 50% genetic meet. A female can also become a parent through surrogacy. Some parents may be Adoption, adoptive parents, who nurture and raise an offspring, but are not related to the child. Orphans without adoptive parents can be raised by their grandparents or other family members. A parent can also be elaborated as an ancestor removed one generation. With recent medical advances, it is possible to have more than two biological parents. Examples of Third-party reproduction, third biological parents include instances involving surrogacy or a third person who has provided DNA samples during an assisted reproductive procedure that has altered the recipients' genetic material. The most common types of parents are mothers, fathers, step-paren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inheritance
Inheritance is the practice of receiving private property, titles, debts, entitlements, privileges, rights, and obligations upon the death of an individual. The rules of inheritance differ among societies and have changed over time. Officially bequeathing private property and/or debts can be performed by a testator via will, as attested by a notary or by other lawful means. Terminology In law, an "heir" ( heiress) is a person who is entitled to receive a share of property from a decedent (a person who died), subject to the rules of inheritance in the jurisdiction where the decedent was a citizen, or where the decedent died or owned property at the time of death. The inheritance may be either under the terms of a will or by intestate laws if the deceased had no will. However, the will must comply with the laws of the jurisdiction at the time it was created or it will be declared invalid (for example, some states do not recognise handwritten wills as valid, or only in ...

Common Law
Common law (also known as judicial precedent, judge-made law, or case law) is the body of law primarily developed through judicial decisions rather than statutes. Although common law may incorporate certain statutes, it is largely based on precedent—judicial rulings made in previous similar cases. The presiding judge determines which precedents to apply in deciding each new case. Common law is deeply rooted in Precedent, ''stare decisis'' ("to stand by things decided"), where courts follow precedents established by previous decisions. When a similar case has been resolved, courts typically align their reasoning with the precedent set in that decision. However, in a "case of first impression" with no precedent or clear legislative guidance, judges are empowered to resolve the issue and establish new precedent. The common law, so named because it was common to all the king's courts across England, originated in the practices of the courts of the English kings in the centuries fo ...

Intestacy
Intestacy is the condition of the estate of a person who dies without a legally valid will, resulting in the distribution of their estate under statutory intestacy laws rather than by their expressed wishes. Alternatively this may also apply where a will or declaration has been made, but only applies to part of the estate; the remaining estate forms the "intestate estate". Intestacy law, also referred to as the law of descent and distribution, which vary by jurisdiction, refers to the body of law ( statutory and case law), establish a hierarchy for inheritance, typically prioritizing close relatives such as spouses, children, and then extended family members and determines who is entitled to the property from the estate under the rules of inheritance. History and the common law Intestacy has a limited application in those jurisdictions that follow civil law or Roman law because the concept of a will is itself less important; the doctrine of forced heirship automatically giv ...

Dibling
A dibling, a portmanteau of donor sibling, or donor-conceived sibling, or donor-sperm sibling, is one of two or more individuals who are biologically connected through donated eggs or sperm. This term is also commonly used in children biologically related through embryo donation. In this instance, the children are full not half biological siblings. The term is not favored among some recipient parents, who prefer the use of half-sibling A sibling is a relative that shares at least one parent with the other person. A male sibling is a brother, and a female sibling is a sister. A person with no siblings is an only child. While some circumstances can cause siblings to be raised .... People born from anonymous or ID release sperm or egg donation are able to find half-siblings conceived using the same gamete donor online through the Donor Sibling Registry or by using commercially available DNA test kits.

First-degree Relatives
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 common ancestors. Each such line connects the two people ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
