K-M9
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 ...

Haplogroup T (Y-DNA)
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 A ...

Haplogroup K2b-P331
Haplogroup K2b (P331), also known as MPS is a human y-chromosome haplogroup that is thought to be less than 3,000 years younger than K, and less than 10,000 years younger than F, meaning it probably is around 50,000 years old, according to the age estimates of Tatiana Karafet et al. 2014. Basal (phylogenetics), Basal K2b* has not been identified in living males. It has been found only in the remains of an individual known as Tianyuan man, who was alive some time between 42,000 and 39,000 years before present, BP, during the upper paleolithic era, near the future site of Beijing, China. (For a time, the basal clade was also attributed, erroneously, to another individual, known as ''RISE94'', who lived 3,000 years BP, in what is now Sweden. However, ''RISE94'' is now known to belong to haplogroup R1a, R1a.) Haplogroup K2b1 (Y-DNA), K2b1 (P397/P399) known previously as Haplogroup MS, and Haplogroup P (Y-DNA), Haplogroup P (P-P295), also known as K2b2 are the only primary clades of K ...

Haplogroup L (Y-DNA)
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 scientifi ...

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 ...

India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ...

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 Q (Y-DNA)
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.

P1 (P-M45) Many ethnic groups with high frequencies of P1, also known as P-M45 and K2b2a, are located in Central Asia and Siberia: 35.4% among Tuvans, 28.3% among Altai-Kizhi (PxQ-M3,R1), and 35% among Nivkh males. § ''May include members of haplogroup R2.'' Q Near universal in the Kets (95%) of Siberia. Very common in pre-modern Native American populations and Selkups, except for the Na-Dene peoples, where it reaches 50-90%.
