Human Y-chromosome DNA haplogroup

Naming convention

Y-DNA haplogroups are defined by the presence of a series of Y-DNA single-nucleotide polymorphisms genetic markers. Subclades are defined by a terminal SNP, the SNP furthest down in the Y-chromosome phylogenetic tree. The Y Chromosome Consortium (YCC) developed a system of naming major Y-DNA haplogroups with the capital letters A through T, with further subclades named using numbers and lower case letters (YCC longhand nomenclature). YCC shorthand nomenclature names Y-DNA haplogroups and their subclades with the first letter of the major Y-DNA haplogroup followed by a dash and the name of the defining terminal SNP.

Y-DNA haplogroup nomenclature is changing over time to accommodate the increasing number of SNPs being discovered and tested, and the resulting expansion of the Y-chromosome phylogenetic tree. This change in nomenclature has resulted in inconsistent nomenclature being used in different sources.

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 precisely of the A1b clade (A2-T in Cruciani et al. 2011), as follows:

• Haplogroup A
  • Haplogroup A00
  • Haplogroup A0 (formerly also A1b)
  • Haplogroup A1 (also A1a-T)
    • Haplogroup A1a (M31)
    • Haplogroup A1b (also A2-T; P108, V221)
      • Haplogroup A1b1a1 (also A2; M14)
      • Haplogroup A1b1b (also A3; M32)

The groups descending from haplogroup F are found in some 90% of the world's population, but almost exclusively outside of sub-Saharan Africa.

F xG,H,I,J,K is rare in modern populations and peaks in South Asia, especially Sri Lanka. It also appears to have long been present in South East Asia; it has been reported at rates of 4–5% in Sulawesi and Lembata. One study, which did not comprehensively screen for other subclades of F-M89 (including some subclades of GHIJK), found that Indonesian men with the SNP P14/PF2704 (which is equivalent to M89), comprise 1.8% of men in West Timor, 1.5% of Flores 5.4% of Lembata 2.3% of Sulawesi and 0.2% in Sumatra. F* (F xF1,F2,F3) has been reported among 10% of males in Sri Lanka and South India, 5% in Pakistan, as well as lower levels among the Tamang people (Nepal), and in Iran. F1 (P91), F2 (M427) and F3 (M481; previously F5) are all highly rare and virtually exclusive to regions/ethnic minorities in Sri Lanka, India, Nepal, South China, Thailand, Burma, and Vietnam. In such cases, however, the possibility of misidentification is considered to be relatively high and some may belong to misidentified subclades of Haplogroup GHIJK.

Found in almost all European countries, but most common in Gagauzia, southeastern Romania, Greece, Italy, Spain, Portugal, Tyrol, and Bohemia with highest concentrations on some Mediterranean islands; uncommon in Northern Europe.

T-M184 is also found in significant minorities of Sciaccensi, Stilfser, Egyptians, Omanis, Sephardi Jews, Ibizans (Eivissencs), and Toubou. It is also found at low frequencies in other parts of the Mediterranean and South Asia.

Haplogroup K2 (K-M526)

Main article: Haplogroup K2

Haplogroup O

Main article: Haplogroup O (Y-DNA)

Haplogroup O (M175) is found with its highest frequency in East Asia and Southeast Asia, with lower frequencies in the South Pacific, Central Asia, South Asia, and islands in the Indian Ocean (e.g. Madagascar, the Comoros).

• Haplogroup O1 (F265/M1354, CTS2866, F75/M1297, F429/M1415, F465/M1422)

Haplogroups K2b1, M & S

Main article: Haplogroup K2b1 (Y-DNA)

No examples of the basal paragroup K2b1* have been identified. Males carrying subclades of K2b1 are found primarily among Papuan peoples, Micronesian peoples, indigenous Australians, and Polynesians.

Its primary subclades are two major haplogroups:

• Haplogroup S (B254) also known as K2b1a: found in the highlands of Papua New Guinea and;
• Haplogroup M (P256) also known as K2b1b: found in New Guinea and Melanesia.

Haplogroup P (K2b2)

Main article: Haplogroup P (Y-DNA)

Haplogroup P (P295) has two primary branches: P1 (P-M45) and the extremely rare P2 (P-B253).

P*, P1* and P2 are found together only on the island of Luzon in the Philippines. In particular, P* and P1* are found at significant rates among members of the Aeta (or Agta) people of Luzon. While, P1* is now more common among living individuals in Eastern Siberia and Central Asia, it is also found at low levels in mainland South East Asia and South Asia. Considered together, these distributions tend to suggest that P* emerged from K2b in South East Asia.

P1 is also the parent node of two primary clades:

• Haplogroup Q (Q-M242) and;
• Haplogroup R (R-M207). These share the common marker M45 in addition to at least 18 other SNPs.

Haplogroup Q (MEH2, M242, P36) found in Siberia and the Americas Haplogroup R (M207, M306): found in Europe, West Asia, Central Asia, and South Asia

Main article: Haplogroup R (Y-DNA)

Haplogroup R is defined by the SNP M207. The bulk of Haplogroup R is represented in the descendant subclade R1 (M173), which originated in Siberia. R1 has two descendant subclades: R1a and R1b.

R1a is associated with the proto-Indo-Iranian and Balto-Slavic peoples, and is now found predominantly in Central Asia, South Asia, and Eastern Europe.

Haplogroup R1b is the dominant haplogroup of Western Europe and is also found sparsely distributed among various peoples of Asia and Africa. Its subclade R1b1a2 (M269) is the haplogroup that is most commonly found among modern Western European populations, and has been associated with the Italo-Celtic and Germanic peoples.
