Haplogroup Q-M242
Haplogroup Q or Q-M242 is a Y-chromosome DNA haplogroup. It has one primary subclade, Haplogroup Q1 (L232/S432), which includes numerous subclades that have been sampled and identified in males among modern populations. Q-M242 is the predominant Y-DNA haplogroup among Native Americans and several peoples of Central Asia and Northern Siberia. Origins Haplogroup Q-M242 is one of the two branches of P1-M45, the other being R-M207. P1, as well as R* and Q* were observed among Ancient North Eurasians, a deeply European hunter-gatherer related population. Q-M242 is believed to have arisen around the Altai Mountains area (or South Central Siberia), approximately 17,000 to 31,700 years ago. However, the matter remains unclear due to limited sample sizes and changing definitions of Haplogroup Q: early definitions used a combination of the SNPs M242, P36.2, and MEH2 as defining mutations. Technical specification of mutation The polymorphism, “M242”, is a C→T transition resid ...

Central Asia
Central Asia, also known as Middle Asia, is a subregion, region of Asia that stretches from the Caspian Sea in the west to western China and Mongolia in the east, and from Afghanistan and Iran in the south to Russia in the north. It includes the former Soviet Union, Soviet republics of the Soviet Union, republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan, which are colloquially referred to as the "-stans" as the countries all have names ending with the Persian language, Persian suffix "-stan", meaning "land of". The current geographical location of Central Asia was formerly part of the historic region of Turkestan, Turkistan, also known as Turan. In the pre-Islamic and early Islamic eras ( and earlier) Central Asia was inhabited predominantly by Iranian peoples, populated by Eastern Iranian languages, Eastern Iranian-speaking Bactrians, Sogdians, Khwarezmian language, Chorasmians and the semi-nomadic Scythians and Dahae. After expansion by Turkic peop ...

Ancient North Eurasian
In archaeogenetics, the term Ancient North Eurasian (generally abbreviated as ANE) is the name given to an ancestral component that represents a lineage ancestral to the people of the Mal'ta–Buret' culture and populations closely related to them, such as from Afontova Gora and the Yana Rhinoceros Horn Site, and populations descended from them. ANE ancestry developed from a sister lineage of West-Eurasians with significant admixture from early East Asians. ANE ancestry has spread throughout Eurasia and the Americas in various migrations since the Upper Paleolithic, and more than half of the world's population today derives between 5 to 40% of their genomes from the Ancient North Eurasians. Significant ANE ancestry can be found in the indigenous peoples of the Americas, as well as in regions of Europe, South Asia, Central Asia, and Siberia. It has been suggested that their mythology may have included a narrative, found in both Indo-European and some Native American fables, in wh ...

Haplogroup R (Y-DNA)
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, that R-M207 has long been present among Native Americans in North America – a theory that has not yet been widely accepted. According to geneticist Spencer Wells, haplogroup K, from which haplogroups P and Q descend, originated in the Middle East or Central Asia. "Given the widespread distribution of K, it probably arose somewhere in the Middle East or Central Asia, perhaps in the region of Iran or Pakistan." However, Karafet et al. (2014) proposed that "rapid diversification ... of K-M526", also known as K2, likely occurred in Southeast Asia (near Indonesia) and later expanded to mainland Asia, although they could ...

Haplogroup P1 (Y-DNA)
Haplogroup P1, also known as P-M45 and K2b2a, is a Y-chromosome DNA haplogroup in human genetics. Defined by the SNPs M45 and PF5962, P1 is a primary branch (subclade) of P (P-P295; K2b2). The only primary subclades of P1 are Haplogroup Q (Q-M242) and Haplogroup R (R-M207). These haplogroups now comprise most of the male lineages among Native Americans, Europeans, Central Asia and South Asia, among other parts of the world. P1 (M45) likely originated in Central Asia or Siberia, with basal P1* (P1xQ,R) now most common among individuals in Siberia and Central Asia.Miroslava Derenko et al 2005 Contrasting patterns of Y-chromosome variation in South Siberian populations from Baikal and Altai-Sayan regionsZgms.cm.umk.plE.

Haplogroup
A haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup (haploid from the el, ἁπλοῦς, ''haploûs'', "onefold, simple" and en, 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 chromosomal regions that are closely linked and that tend to be inherited together. As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes. Haplogroups pertain to a single line of descent. As such, membership of a haplogroup, by any individual, relies on a relatively small proportion of the genetic material possessed by that individual. Each haplogroup originates from, and remains part of, a preceding single haplogroup (or paragroup). As such, any related group of haplogroups may be precisely modelled as a nested hierarchy, in which each set (hap ...

Far North (Russia)
The Extreme North or Far North (russian: Крайний Север, Дальний Север) is a large part of Russia located mainly north of the Arctic Circle and boasting enormous mineral and natural resources. Its total area is about , comprising about one-third of Russia's total area. Formally, the regions of the Extreme North comprise the whole of Chukotka Autonomous Okrug, Kamchatka Krai, Magadan Oblast, Murmansk Oblast and Sakha, as well as certain parts and cities of Arkhangelsk Oblast, Irkutsk Oblast, Khabarovsk Krai, Komi Republic, Krasnoyarsk Krai, Republic of Karelia, Sakhalin Oblast, Tuva, Tyumen Oblast, as well as all islands of the Arctic Ocean, its seas, the Bering Sea, and the Sea of Okhotsk. Due to the harsh conditions of the area, people who work there have traditionally been entitled by the Russian government to higher wages than workers of other regions. As a result of the climate and environment, the List of minor indigenous peoples of Russia#Far North ...

Subclade
In genetics, a subclade is a subgroup of a haplogroup. Naming convention Although human mitochondrial DNA (mtDNA) and Y chromosome DNA (Y-DNA) haplogroups and subclades are named in a similar manner, their names belong to completely separate systems. mtDNA mtDNA haplogroups are defined by the presence of a series of single-nucleotide polymorphism (SNP) markers in the hypervariable regions and the coding region of mitochondrial DNA. They are named with the capital letters A through Z, with further subclades named using numbers and lower case letters. Y-DNA Y-DNA haplogroups are defined by the presence of a series of SNP markers on the Y chromosome. Subclades are defined by a ''terminal SNP'', the SNP furthest down in the Y chromosome phylogenetic tree. Human Y-DNA The Y Chromosome Consortium (YCC) developed a system of naming major human Y-DNA haplogroups with the capital letters A through T, with further subclades named using numbers and lower case letters (YCC longhand nomenc ...

Human Y-chromosome DNA Haplogroup
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by mutations in the non- recombining portions of DNA from the male-specific Y chromosome (called Y-DNA). Many people within a haplogroup share similar numbers of short tandem repeats (STRs) and types of mutations called single-nucleotide polymorphisms (SNPs). The human Y-chromosome accumulates roughly two mutations per generation. "one mutation in every 30 million base pairs" Y-DNA haplogroups represent major branches of the Y-chromosome phylogenetic tree that share hundreds or even thousands of mutations unique to each haplogroup. The Y-chromosomal most recent common ancestor (Y-MRCA, informally known as Y-chromosomal Adam) is the most recent common ancestor (MRCA) from whom all currently living humans are descended patrilineally. Y-chromosomal Adam is estimated to have lived roughly 236,000 years ago in Africa. By examining other bottlenecks most Eurasian men (men from populations outside of Afri ...

Tribes Of Assam
According to the 2001 census, the Scheduled Tribes population as in percentage of the total population of Assam was 12.4 percent. The Assam Tribune reported in 2009 that the tribal communities of Assam now officially account for 15.64 percent of the total population. The Constitution of India categorizes the tribes of Assam into two groups: Scheduled Tribes (Hills) and Scheduled Tribes (Plains). Since hills tribes living in the plains and plains tribes living in the hills in large numbers are not recognised as scheduled tribes in the respective places, the census data may not reflect the correct figures. The Assam Tribune has claimed that if these categories of tribes are counted the actual population. Assamese language is used as the lingua franca by almost all the tribes. Groups The main Scheduled Tribes (Plains) are Bodo , Deori, Sonowal, Mising, Hajong, etc and Karbi, Dimasa etc has Scheduled Tribes (hills) status. List of tribes * In the autonomous Districts of Karbi ...

Mon-Khmer
The Austroasiatic languages , , are a large language family in Mainland Southeast Asia and South Asia. These languages are scattered throughout parts of Thailand, Laos, India, Myanmar, Malaysia, Bangladesh, Nepal, and southern China and are the majority languages of Vietnam and Cambodia. There are around 117 million speakers of Austroasiatic languages. Of these languages, only Vietnamese, Khmer, and Mon have a long-established recorded history. Only two have official status as modern national languages: Vietnamese in Vietnam and Khmer in Cambodia. The Mon language is a recognized indigenous language in Myanmar and Thailand. In Myanmar, the Wa language is the de facto official language of Wa State. Santali is one of the 22 scheduled languages of India. The rest of the languages are spoken by minority groups and have no official status. ''Ethnologue'' identifies 168 Austroasiatic languages. These form thirteen established families (plus perhaps Shompen, which is poorly attest ...
