Patrilineality, also known as the male line, the spear side [1] 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.
In anthropology, a lineage is a unilineal descent group that traces its ancestry to a demonstrably shared ancestor, known as the apical ancestor. [1] [2] [3] Lineages are formed through relationships traced either exclusively through the maternal line (matrilineage), paternal line (patrilineage), or some combination of both (). [4]
Haplogroups can be determined from the remains of historical figures, or derived from genealogical DNA tests of people who trace their direct maternal or paternal ancestry to a noted historical figure. Some contemporary notable figures have made their test results public in the course of news programs or documentaries about this topic; they may ...
It is the presence of this extra genetic material that is thought to account for the symptoms seen in some people with idic(15). Individuals with idic(15) have a total of four copies of this chromosome 15 region instead of the usual two copies (1 copy each on the maternal and paternal chromosomes). The term isodicentric refers to a duplication ...
Imprinting is defined as the differential expression of paternal and maternal alleles of a gene, due to epigenetic marks introduced onto the chromosome during the production of egg and sperm. These marks usually lead to differential expression of the specific sets of genes from the maternal and paternal chromosomes.
In modern Rabbinic Judaism, the traditional method of determining Jewishness relies on tracing one's maternal line. According to halakha, the recognition of someone as fully Jewish requires them to have been born to a Jewish mother. [1] A person who is born to a non-Jewish mother and a Jewish father is regarded as Zera Yisrael (lit.
Haplogroup B (M60) is a human Y-chromosome DNA haplogroup common to paternal lineages in Africa.It is a primary branch of the haplogroup BT.. B (M60) is common in parts of Africa, especially the tropical forests of West-Central Africa.
Uniparental inheritance refers to the fact that, in most organisms, many offspring inherit organelle genes from only one parent. However, this is not a general law. Many organisms that have the ability to differentiate maternal and paternal sexes will produce offspring with a mixture of maternal, paternal, and biparental mitochondrial DNA. [8]
