Haplogroup L-M20
Haplogroup L-M20 is a human Y-DNA haplogroup, which is defined by SNPs M11, M20, M61 and M185. As a secondary descendant of haplogroup K and a primary branch of haplogroup LT, haplogroup L currently has the alternative phylogenetic name of K1a, and is a sibling of haplogroup T (a.k.a. K1b). The presence of L-M20 has been observed at varying levels throughout South Asia, peaking in populations native to Balochistan (28%), and Southern India (19%), where as its peak level up to 68% is observed in Korova Tribes or Koraga people of coastal Karnataka and north Kerala. The clade also occurs in Afghanistan,Tajikistan and Anatolia, as well as at lower frequencies in Iran. It has also been present for millennia at very low levels in the Caucasus, Europe and Central Asia. The subclade L2 (L-L595) has been found in Europe and Western Asia, but is extremely rare. Phylogenetic tree There are several confirmed and proposed phylogenetic trees available for haplogroup L-M20. The scientif ...

Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabia (including the Arabian Peninsula and Bahrain), Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sinai Region) and all of Turkey (not just the part barring East Thrace). ...

Afshar Tribe
Afshar ( az, Əfşar افشار; tr, Avşar, ''Afşar''; tk, Owşar; fa, اَفشار, Āfshār) is a tribe of Oghuz Turkic origin, that split into several groups in Iran, Turkey and Afghanistan. During the Seljuk conquests of the 11th century, they moved from Central Asia into the Middle East. They are noted in history for being one of the Qizilbash tribes that helped establish the Safavid dynasty of Iran, and for being the source of descent of Iran's Afsharid dynasty. Nader Shah, who became the monarch of Iran in 1736, was from the Qereklu tribe ( fa, قرخلو) of Afshars. Afshars mainly inhabit Iran, where they remain a largely nomadic group. Today, the Afshars are variously grouped as a branch of the Azerbaijanis and Turkmens or Turkomans (a common general term used for people of Oghuz Turkic origin). The founders of the Germiyanids, Baku Khanate, Zanjan Khanate, Khalkhal Khanate, and Urmia Khanate were also of Afshar descent. The founder of the Karamanids may have ...

Koraga People
The Koraga are a tribal community found mainly in the Dakshina Kannada, Udupi districts of Karnataka and the Kasaragod district of Kerala, south India. These areas in Karnataka, are altogether often referred to as Tulunaad, which roughly corresponds to the boundaries of the erstwhile South Canara district. They are also found in small numbers in adjoining districts of Uttara Kannada, Shimoga and Kodagu. The Koraga are classified by the Government of India as a Scheduled Tribe. The Koraga, who numbered 16,071 according to the 2001 census of India, have their own language, classified as an independent Dravidian language, which is strongly influenced by Tulu, Kannada, Malayalam, languages commonly found in their area. Social status The 1901 census report noted the Koraga as being a lowly tribe of basket-makers and labourers, some of whom were employed as scavengers. They remain today among the untouchables, being considered as ritually polluted by Hindus, but there have in the pas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South India
South India, also known as Dakshina Bharata or Peninsular India, consists of the peninsular southern part of India. It encompasses the Indian states of Andhra Pradesh, Karnataka, Kerala, Tamil Nadu, and Telangana, as well as the union territories of Lakshadweep and Puducherry, comprising 19.31% of India's area () and 20% of India's population.

Balochistan, Pakistan
Balochistan (; bal, بلۏچستان; ) is one of the four provinces of Pakistan. Located in the southwestern region of the country, Balochistan is the largest province of Pakistan by land area but is the least populated one. It shares land borders with the Pakistani provinces of Khyber Pakhtunkhwa and Punjab to the north-east and Sindh to the south-east. It shares International borders with Iran to the west and Afghanistan to the north; It is also bound by the Arabian Sea to the south. Balochistan is an extensive plateau of rough terrain divided into basins by ranges of sufficient heights and ruggedness. It has the world's largest deep sea port, The Port of Gwadar lying in the Arabian Sea.

Haplogroup T-M184
Haplogroup T-M184, also known as Haplogroup T, is a human Y-chromosome DNA haplogroup. The unique-event polymorphism that defines this clade is the single-nucleotide polymorphism known as ''M184''. Other SNPs – ''M272'', ''PAGES129'', ''L810'', ''L455'', ''L452'', and ''L445'' – are considered to be phylogenetically equivalent to ''M184''. As a primary branch of haplogroup LT (a.k.a. K1), the basal, undivergent haplogroup T* currently has the alternate phylogenetic name of K1b and is a sibling of haplogroup L* (a.k.a. K1a). (Before 2008, haplogroup T and its subclades were known as haplogroup K2. The name K2 has since been reassigned to a primary subclade of haplogroup K.) It has two primary branches: T1 (T-L206) and T2 (T-PH110). T-M184 is unusual in that it is both geographically widespread and relatively rare. T1 (T-L206) – the numerically dominant primary branch of T-M184 – appears to have originated in Western Asia, and possibly spread from there into the East ...

Phylogenetic Name
Phylogenetic nomenclature is a method of nomenclature for taxa in biology that uses phylogenetic definitions for taxon names as explained below. This contrasts with the traditional approach, in which taxon names are defined by a '' type'', which can be a specimen or a taxon of lower rank, and a description in words. Phylogenetic nomenclature is currently regulated by the '' International Code of Phylogenetic Nomenclature'' (''PhyloCode''). Definitions Phylogenetic nomenclature ties names to clades, groups consisting of an ancestor and all its descendants. These groups can equivalently be called monophyletic. There are slightly different ways of specifying the ancestor, which are discussed below. Once the ancestor is specified, the meaning of the name is fixed: the ancestor and all organisms which are its descendants are included in the named taxon. Listing all these organisms (i.e. providing a full circumscription) requires the full phylogenetic tree to be known. In practice, the ...

Haplogroup LT
Haplogroup LT or LT-L298/P326, also known as K1 (and until 2008 as Haplogroup K2), is a Y-chromosome DNA haplogroup. Its defining SNP mutations are L298 and P326. No confirmed cases of the basal paragroup LT* have been identified among living males or human remains. Structure It is generally believed that LT (L298/P326) originated somewhere in Asia. LT is a direct descendant of haplogroup K (M9). The direct descendants of LT are haplogroup L (M20), also known as K1a, and haplogroup T (M184), also known as K1b.International Society of Genetic Genealogy'', 2015, ''Y-DNA Haplogroup Tree 2015'' (30 May 2015).

Haplogroup K (Y-DNA)
Haplogroup K or K-M9 is a human Y-chromosome DNA haplogroup. A sublineage of haplogroup IJK, K-M9, and its descendant clades represent a geographically widespread and diverse haplogroup. The lineages have long been found among males on every continent except Antarctica. The direct descendants of K-M9 are Haplogroup K2 (formerly KxLT; K-M526) and Haplogroup K1 (L298 = P326, also known as LT). Origins and distribution Y-DNA haplogroup K-M9 is an old lineage that arose approximately 47,000-50,000 years ago, probably in South Asia According to a study by geneticist Spencer Wells, haplogroup K, from which haplogroup P descend, originated in the Middle East or Central Asia. It is likely that haplogroup P diverged somewhere in South Asia into P1, which expanded into Siberia and Northern Eurasia, and into P2, which expanded into Oceania and Southeast Asia. "Given the widespread distribution of K, it probably arose somewhere in the Middle East or Central Asia, perhaps in the region of ...

Single-nucleotide Polymorphism
In genetics, a single-nucleotide polymorphism (SNP ; plural SNPs ) is a germline substitution of a single nucleotide at a specific position in the genome. Although certain definitions require the substitution to be present in a sufficiently large fraction of the population (e.g. 1% or more), many publications do not apply such a frequency threshold. For example, at a specific base position in the human genome, the G nucleotide may appear in most individuals, but in a minority of individuals, the position is occupied by an A. This means that there is a SNP at this specific position, and the two possible nucleotide variations – G or A – are said to be the alleles for this specific position. SNPs pinpoint differences in our susceptibility to a wide range of diseases, for example age-related macular degeneration (a common SNP in the CFH gene is associated with increased risk of the disease) or nonalcoholic fatty liver disease (a SNP in the PNPLA3 gene is associated with inc ...

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 ...
