Haplogroup Q-L275 or Haplogroup Q2 (formerly Haplogroup Q1b) is a human Y-chromosome DNA haplogroup believed to have originated in Eurasia. Haplogroup Q-L275 is defined by the presence of the L275 single-nucleotide polymorphism (SNP). Haplogroup Q-L275 can be identified through genealogical DNA testing.
Q-L275 has descendants across Europe, Central Asia, and South Asia. Q-M378 is phylogeographically restricted to southwest Asia. [1]
Q-L275 has not been identified in pre-Columbian groups in the Americas, but is sporadically found among modern Native Americans. Potential sources in indigenous populations are European colonists and religious missionaries. According to Batfaglia, et al, Q-M378 in Native American populations can be attributed to historical migrants from Southwest Asia in the modern historical period. [1]
The problematic phylogeny sampling of early studies has been demonstrated by subsequent studies that have found the Q-M378 descendant branch in South Asia.
According to Behar et al. 5% of Ashkenazi males belong to haplogroup Q. [2] This has subsequently been found to be entirely Q-L275's Q-M378 subclade and is further restricted to the Q-L245 branch.
Q-L245 This branch was discovered by citizen scientists. It is a descendant branch of the Q-M378 lineage and is the most common branch in West Asian groups such as Iranians and Jewish populations.
Q-L272.1 This branch was discovered by citizen scientists. It has only been identified in one Sicilian sample.
Q-L301 This branch was discovered by citizen scientists. They have identified it in two unrelated Iranian samples.
Q-L315 This branch was discovered by citizen scientists. It has only been identified in one Ashkenazi Jewish sample. Thus, it is presumed to have arisen after the Q-L245 branch to which it belongs became part of the pre-Diaspora Jewish population.
Q-L327 This branch was discovered by citizen scientists. It has only been identified in one Azorean sample.
Q-L619.2 This branch was discovered by citizen scientists. They have identified it in two unrelated Armenian samples.
Q-P306 This branch was discovered by the University of Arizona research group headed by Dr. Michael Hammer in a Southeast Asian sample. It has been identified by citizen scientists in South Asians.
Q-M378 — It is widely distributed in Europe, South Asia, and West Asia. It is found among samples of Hazaras and Sindhis. [3] It has been found in one individual in a small sample of eleven Lachungpa in Sikkim. [4] It is also found in the Uyghurs of North-Western China in two separate groups. [5] Some Western Jews belong to Q-M378 as well. Q-M378's subbranch Q-L245's subclades Q-Y2200 and Q-YP1035 are the only varieties of haplogroup Q that are found in Ashkenazi Jews. [6] Citizen scientists found that some Sephardic Jews carry different subclades of Q-L245, including Q-BZ3900, Q-YP745, and Q-YP1237.
Q-L275 is currently defined by the SNPs L275, L314, L606, and L612.

Haplogroup G (M201) is a human Y-chromosome haplogroup. It is one of two branches of the parent haplogroup GHIJK, the other being HIJK.
Haplogroup J-M304, also known as J, is a human Y-chromosome DNA haplogroup. It is believed to have evolved in Western Asia. The clade spread from there during the Neolithic, primarily into North Africa, the Horn of Africa, the Socotra Archipelago, the Caucasus, Europe, Anatolia, Central Asia, South Asia, and Southeast Asia.
Haplogroup F, also known as F-M89 and previously as Haplogroup FT, is a very common Y-chromosome haplogroup. The clade and its subclades constitute over 90% of paternal lineages outside of Africa.
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.
Haplogroup Q-M3 (Y-DNA) is a Y-chromosome DNA haplogroup. Haplogroup Q-M3 is a subclade of Haplogroup Q-L54. Haplogroup Q-M3 was previously known as Haplogroup Q3; currently Q-M3 is Q1b1a1a below Q1b-M346.
Haplogroup E-M132, formerly known as E-M33 (E1a), is a human Y-chromosome DNA haplogroup. Along with E-P177, it is one of the two main branches of the older E-P147 paternal clade. E-M132 is divided into two primary sub-branches, E-M44 and E-Z958, with many descendant subclades.
Haplogroup E-M75 is a human Y-chromosome DNA haplogroup. Along with haplogroup E-P147, it is one of the two main branches of the older haplogroup E-M96.
In human population genetics, Y-Chromosome haplogroups define the major lineages of direct paternal (male) lines back to a shared common ancestor in Africa. Men in the same haplogroup share a set of differences, or markers, on their Y-Chromosome, which distinguish them from men in other haplogroups. These UEPs, or markers used to define haplogroups, are SNP mutations. Y-Chromosome Haplogroups all form "family trees" or "phylogenies", with both branches or sub-clades diverging from a common haplogroup ancestor, and also with all haplogroups themselves linked into one family tree which traces back ultimately to the most recent shared male line ancestor of all men alive today, called in popular science Y Chromosome Adam.
In human genetics, Haplogroup G-M285 or G-M342, also known as Haplogroup G1, is a Y-chromosome haplogroup. Haplogroup G1 is a primary subclade of haplogroup G.
Genetic studies of Jews are part of the population genetics discipline and are used to analyze the ancestry of Jewish populations, complementing research in other fields such as history, linguistics, archaeology, and paleontology. These studies investigate the origins of various Jewish ethnic divisions. In particular, they examine whether there is a common genetic heritage among them. The medical genetics of Jews are studied for population-specific diseases.
Haplogroup Q-M346 is a subclade of Y-DNA Haplogroup Q. Haplogroup Q-M346 is defined by the presence of the M346 Single Nucleotide Polymorphism (SNP).
Haplogroup Q-L54 is a subclade of Y-DNA haplogroup Q-L53. Q1a3a-L54 is defined by the presence of the L54 Single Nucleotide Polymorphism (SNP).
Haplogroup Q-NWT01 is a subclade of Y-DNA Haplogroup Q-MEH2. Haplogroup Q-NWT01 is defined by the presence of the NWT01 Single Nucleotide Polymorphism (SNP).
Haplogroup Q-P89.1 is a subclade of Y-DNA Haplogroup Q-MEH2. Haplogroup Q-P89.1 is defined by the presence of the P89.1 Single Nucleotide Polymorphism (SNP). In 2010, Q-P89.1 was reclassified as "private" and removed from the haplotree.
Haplogroup Q-M25, also known as Q1a1b is a subclade or branch of human Y-DNA haplogroup Q-F1096 (Q1a1), which is, in turn, a subclade of Q-MEH2 (Q1a). In human genetics, each Y-DNA haplogroup constitutes a biological paternal lineages back to a shared common male ancestor.
Haplogroup Q-M120, also known as Q1a1a1, is a Y-DNA haplogroup. It is the only primary branch of haplogroup Q1a1a (F746/NWT01). The lineage is most common amongst modern populations in eastern Eurasia.

Haplogroup A-L1085, also known as haplogroup A0-T is a human Y-DNA haplogroup. It is part of the paternal lineage of almost all humans alive today. The SNP L1085 has played two roles in population genetics: firstly, most Y-DNA haplogroups have diverged from it and; secondly, it defines the undiverged basal clade A-L1085*.
