A brother (pl.: brothers or brethren) is a man or boy who shares one or more parents with another; a male sibling. The female counterpart is a sister. Although the term typically refers to a familial relationship, it is sometimes used endearingly to refer to non-familial relationships. A full brother is a first degree relative.
Fratricide (from Latin fratricidium; from frater 'brother' and -cīdium 'killing' – the assimilated root of caedere 'to kill, cut down') is the act of killing one's own brother.
It can either be done directly or via the use of either a hired or an indoctrinated intermediary (an assassin). The victim need not be the perpetrator's biological brother. In a military context, fratricide refers to a service member killing a comrade.
Incest (/ˈɪnsɛst/ IN-sest) is sex between close relatives, for example a brother, sister, or parent. This typically includes any kind of sexual activity between people in consanguinity (blood relations), and sometimes those related by 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-siblings, stepsiblings, and adoptive siblings, albeit sometimes with less intensity. Third-degree relatives (such as half-aunt, half-nephew, first cousin) on average have 12.5% common genetic heritage, and sexual relations between them are viewed differently in various cultures, from being discouraged to being socially acceptable. Children of incestuous relationships have been regarded as illegitimate, and are still so regarded in some societies today. In most cases, the parents did not have the option to marry to remove that status, as incestuous marriages were, and are, normally also prohibited.
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.
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.
