In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA.Haplogroups are used to represent the major branch points on the mitochondrial phylogenetic tree. Understanding the evolutionary path of the female lineage has helped population geneticists trace the matrilineal inheritance of modern humans …

A haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup (haploid from the Greek: ἁπλοῦς, haploûs, "onefold, simple" and English: group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplogroup is a combination of alleles at different ...

Major Y-DNA haplogroups Haplogroups A and B. Haplogroup A is the NRY (non-recombining Y) macrohaplogroup from which all modern paternal haplogroups descend.It is sparsely distributed in Africa, being concentrated among Khoisan populations in the southwest and Nilotic populations toward the northeast in the Nile Valley. BT is a subclade of haplogroup A, more …

Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also …

Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup.It is both numerous and widespread amongst modern populations. Some descendant subclades have been found since pre-history in Europe, Central Asia and South Asia.Others have long been present, at lower levels, in parts of West Asia and Africa.Some authorities have also suggested, more controversially, …

Listed here are notable ethnic groups and populations from Western Asia, Egypt and South Caucasus by human Y-chromosome DNA haplogroups based on relevant studies. The samples are taken from individuals identified with the ethnic and linguistic designations in the first two columns, the third column gives the sample size studied, and the other columns give the …

Maghrebis or Maghrebians (Arabic: المغاربيون) is a modern Arabic term meaning "Westerners", mainly referring to the western part of the Arab world. They are the inhabitants of the Maghreb region, the westernmost part of North Africa.Maghrebis were known in medieval times as Roman Africans or Moors.The term Moor is derived from Mauri, the Roman name for the Berbers of …

Son zamanlarda yapılan araştırmalara göre, Anadolu Türklerinin Orta Asya’daki Türk halkları ile genetik yönden benzerlik gösterdiği görülmektedir. Orta Asya Türk halklarının Y-Haplogroup DNA’sında sıklıkla bulunan R1a, R1b ve J kromozomları benzer oranlarda Anadolu Türklerindeki oranlarla örtüşmektedir. Bu araştırmalar, Türklerin Anadolu'ya gelmeden önce de ...

Haplogroup R-M269 is the sub-clade of human Y-chromosome haplogroup R1b that is defined by the SNP marker M269.According to ISOGG 2020 it is phylogenetically classified as R1b1a1b.It underwent intensive research and was previously classified as R1b1a2 (2003 to 2005), R1b1c (2005 to 2008), R1b1b2 (2008 to 2011) and R1b1a1a2 (2011 to 2020).

Early human migrations are the earliest migrations and expansions of archaic and modern humans across continents. They are believed to have begun approximately 2 million years ago with the early expansions out of Africa by Homo erectus.This initial migration was followed by other archaic humans including H. heidelbergensis, which lived around 500,000 years ago and …
