Male Line
Patrilineality, also known as the male line, the spear side or agnatic kinship, is a common kinship system in which an individual's family membership derives from and is recorded through their father's lineage. It generally involves the inheritance of property, rights, names, or titles by persons related through male kin. This is sometimes distinguished from cognate kinship, through the mother's lineage, also called the spindle side or the distaff side. A patriline ("father line") is a person's father, and additional ancestors, as traced only through males. In the Bible In the Bible, family and tribal membership appears to be transmitted through the father. For example, a person is considered to be a priest or Levite, if his father is a priest or Levite, and the members of all the Twelve Tribes are called Israelites because their father is Israel (Jacob). In the first lines of the New Testament, the descent of Jesus Christ is counted through the male lineage from Abraham throug ...

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 Human, humans do with these basic facts of lifemating, gestation, Parenting, 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 [we] can 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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Male-preference Primogeniture
Primogeniture () is the right, by law or custom, of the firstborn legitimate child to inherit all or most of their parent's estate in preference to shared inheritance among all or some children, any illegitimate child or any collateral relative. In most contexts, it means the inheritance of the firstborn son (agnatic primogeniture); it can also mean by the firstborn daughter (matrilineal primogeniture), or firstborn child (absolute primogeniture). Its opposite analogue is partible inheritance. Description The common definition given is also known as male-line primogeniture, the classical form popular in European jurisdictions among others until into the 20th century. In the absence of male-line offspring, variations were expounded to entitle a daughter or a brother or, in the absence of either, to another collateral relative, in a specified order (e.g., male-preference primogeniture, Salic primogeniture, semi-Salic primogeniture). Variations have tempered the traditional, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agnatic Seniority
Agnatic seniority is a patrilineality, patrilineal principle of inheritance where the order of succession to the throne prefers the monarch's younger brother over the monarch's own sons. A monarch's children (the next generation) succeed only after the males of the elder generation have all been exhausted. Agnatic seniority excludes females of the dynasty and their descendants from the succession. Contrast Primogeniture#Agnatic primogeniture, agnatic primogeniture, where the king's sons stand higher in succession than his brothers. Description In hereditary monarchy, monarchies, particularly in more ancient times, seniority was a much-used principle of order of succession. The Ottoman Empire evolved from an elective succession (following the principle of agnatic seniority) to a succession inherited by the law of agnatic seniority. In succession based on rotation (close to seniority), all (male) members of the dynasty were entitled to the monarchy, in principle. However, this ...

Genetic Marker
A genetic marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species. It can be described as a variation (which may arise due to mutation or alteration in the genomic loci) that can be observed. A genetic marker may be a short DNA sequence, such as a sequence surrounding a single base-pair change ( single nucleotide polymorphism, SNP), or a long one, like minisatellites. Background For many years, gene mapping was limited to identifying organisms by traditional phenotypes markers. This included genes that encoded easily observable characteristics, such as blood types or seed shapes. The insufficient number of these types of characteristics in several organisms limited the possible mapping efforts. This prompted the development of gene markers, which could identify genetic characteristics that are not readily observable in organisms (such as protein variation). Types Some commonly used types of genetic markers ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Clock
The molecular clock is a figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged. The biomolecular data used for such calculations are usually nucleotide sequences for DNA, RNA, or amino acid sequences for proteins. Early discovery and genetic equidistance The notion of the existence of a so-called "molecular clock" was first attributed to Émile Zuckerkandl and Linus Pauling who, in 1962, noticed that the number of amino acid differences in hemoglobin between different lineages changes roughly linearly with time, as estimated from fossil evidence. They generalized this observation to assert that the rate of evolutionary change of any specified protein was approximately constant over time and over different lineages (known as the molecular clock hypothesis). The genetic equidistance phenomenon was first noted in 1963 by Emanuel Margoliash, who wrote: "It appears that the number ...

Most Recent Common Ancestor
A most recent common ancestor (MRCA), also known as a last common ancestor (LCA), is the most recent individual from which all organisms of a set are inferred to have descended. The most recent common ancestor of a higher taxon is generally assumed to have been a species. The term is also used in reference to the ancestry of groups of genes (haplotypes) rather than organisms. The ancestry of a set of individuals can sometimes be determined by referring to an established pedigree, although this may refer only to patrilineal or matrilineal lines for sexually-reproducing organisms with two parents, four grandparents, etc. However, in general, it is impossible to identify the exact MRCA of a large set of individuals, but an estimate of the time at which the MRCA lived can often be given. Such ''time to most recent common ancestor'' (''TMRCA'') estimates can be given based on DNA test results and established mutation rates as practiced in genetic genealogy, or by reference to a non- ...

Y-chromosomal Adam
In human genetics, the Y-chromosomal Adam (more technically known as the Y-chromosomal most recent common ancestor, shortened to Y-MRCA), is the patrilineal most recent common ancestor (MRCA) from whom all currently living humans are descended. He is the most recent male from whom all living humans are descended through an unbroken line of their male ancestors. The term Y-MRCA reflects the fact that the Y chromosomes of all currently living human males are directly derived from the Y chromosome of this remote ancestor. The analogous concept of the matrilineal most recent common ancestor is known as " Mitochondrial Eve" (mt-MRCA, named for the matrilineal transmission of mtDNA), the most recent woman from whom all living humans are descended matrilineally. As with "Mitochondrial Eve", the title of "Y-chromosomal Adam" is not permanently fixed to a single individual, but can advance over the course of human history as paternal lineages become extinct.

Y Chromosome
The Y chromosome is one of two sex chromosomes in therian mammals and other organisms. Along with the X chromosome, it is part of the XY sex-determination system, in which the Y is the sex-determining chromosome because the presence of the Y chromosome causes offspring produced in sexual reproduction to be of male sex. In mammals, the Y chromosome contains the SRY gene, which triggers development of male gonads. The Y chromosome is passed only from male parents to male offspring. Overview Discovery The Y chromosome was identified as a sex-determining chromosome by Nettie Stevens at Bryn Mawr College in 1905 during a study of the mealworm ''Tenebrio molitor''. Edmund Beecher Wilson independently discovered the same mechanisms the same year, working with Hemiptera. Stevens proposed that chromosomes always existed in pairs and that the smaller chromosome (now labelled "Y") was the pair of the X chromosome discovered in 1890 by Hermann Henking. She realized that th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Absolute Primogeniture
Primogeniture () is the right, by law or custom, of the firstborn legitimate child to inherit all or most of their parent's estate in preference to shared inheritance among all or some children, any illegitimate child or any collateral relative. In most contexts, it means the inheritance of the firstborn son (agnatic primogeniture); it can also mean by the firstborn daughter (matrilineal primogeniture), or firstborn child (absolute primogeniture). Its opposite analogue is partible inheritance. Description The common definition given is also known as male-line primogeniture, the classical form popular in European jurisdictions among others until into the 20th century. In the absence of male-line offspring, variations were expounded to entitle a daughter or a brother or, in the absence of either, to another collateral relative, in a specified order (e.g., male-preference primogeniture, Salic primogeniture, semi-Salic primogeniture).

Principality Of Liechtenstein
Liechtenstein (, ; ; ), officially the Principality of Liechtenstein ( ), is a doubly landlocked German-speaking microstate in the Central European Alps, between Austria in the east and north and Switzerland in the west and south. Liechtenstein is a semi-constitutional monarchy headed by the prince of Liechtenstein of the House of Liechtenstein, currently led by Hans-Adam II. It is Europe's fourth-smallest country, with an area of just over and a population of 40,023. It is the world's smallest country to border two countries, and is one of the few countries with no debt. Liechtenstein is divided into 11 municipalities. Its capital is Vaduz, and its largest municipality is Schaan. It is a member of the United Nations, the European Free Trade Association, and the Council of Europe. It is not a member state of the European Union, but it participates in both the Schengen Area and the European Economic Area. It has a customs union and a monetary union with Switzerland, with i ...

Salic Law
The Salic law ( or ; ), also called the was the ancient Frankish Civil law (legal system), civil law code compiled around AD 500 by Clovis I, Clovis, the first Frankish King. The name may refer to the Salii, or "Salian Franks", but this is debated. The written text is in Late Latin, and contains some of the earliest known instances of Old Dutch. It remained the basis of Frankish law throughout the early Medieval period, and influenced future History of Western law, European legal systems. The best-known tenet of the old law is the principle of exclusion of women from inheritance of thrones, fiefs, and other property. The Salic laws were arbitrated by a committee appointed and empowered by the King of the Franks. Dozens of manuscripts dating from the sixth to eighth centuries and three emendations as late as the ninth century have survived. Salic law provided written codification of both civil law, such as the statutes governing inheritance, and criminal law, such as the punishme ...
