Haplogroup R-M269 is the sub-clade of human Y-chromosome haplogroup R1b that is defined by the SNP marker M269. According to ISOGG 2020 it is phylogenetically classified as R1b1a1b. It underwent intensive research and was previously classified as R1b1a2 (2003 to 2005), R1b1c (2005 to 2008), R1b1b2 (2008 to 2011) and R1b1a1a2 (2011 to 2020). [6]
R-M269 is of particular interest for the genetic history of Western Europe, being the most common European haplogroup. It increases in frequency on an east to west gradient (its prevalence in Poland estimated at 22.7%, compared to Wales at 92.3%). It is carried by approximately 110 million European men (2010 estimate). [3] The age of the mutation M269 is estimated at 4,000 to 10,000 years ago. [2] [3]
R-M269 had formerly been dated to the Upper Paleolithic, [7] but by about 2010 it was thought to have formed near the beginning of the Neolithic Revolution, about 10,000 years ago. [8] [9] [10] More recent archaeogenetics studies since 2015, however, strongly suggest an origin among Eneolithic hunter-gatherers from eastern Europe. [4] [11]
Balaresque et al. (2010) based on the pattern of Y-STR diversity argued for a single source in the Near East and introduction to Europe via Anatolia in the Neolithic Revolution. In this scenario, Mesolithic hunter-gatherers in Europe would have been nearly replaced by the incoming farmers. By contrast, Busby et al. (2012) could not confirm the results of Balaresque et al. (2010) and could not make credible estimates of the age of R-M269 based on Y-STR diversity. [3] [12] Furthermore, more recent studies have found that the Y-DNA of Early European Farmers is typically haplogroup G2a. [13]
According to a 2015 study, [4] a hunter-gatherer from Samara (dated 5640-5555 cal BCE) belonging to haplogroup R1b1(*) was ancestral for both haplogroups R-M269 and R-M478. According to the authors, the occurrence of basal forms of R1b in eastern European hunter-gatherers provides a "geographically plausible source" for haplogroup R-M269. Subclades of R-M269, such as R-Z2103, have been found to be prevalent in ancient DNA found in individuals associated with the Yamnaya culture and related populations, [4] [14] and the dispersal of this haplogroup is associated with the spread of so-called "steppe ancestry" and at least some of the Indo-European languages. [4] [15]
According to Lazaridis et al. (2022), "the most likely hypothesis" is that the entire R-M269 clade originated "in the North Caucasus and steppe to the north". [16]
The subclade R-P311 is substantially confined to Western Europe in modern populations. R-P311 is absent from Neolithic-era ancient DNA found in Western Europe, strongly suggesting that its current distribution is due to population movements within Europe taking place after the end of the Neolithic. The three major subclades of P311 are U106 (S21), L21 (M529, S145), and U152 (S28). These show a clear articulation within Western Europe, with centers in the Low Countries, the British Isles and the Alps, respectively. [17] These lineages are associated with the non-Iberian steppe-related groups of the Bell Beaker culture, and demonstrate the relationship between steppe-related ancestry and R1b-M269 subclades, [14] which are "the major lineage associated with the arrival of Steppe ancestry in western Europe after 2500 BC".

European R1b is dominated by R-M269. It has been found at generally low frequencies throughout central Eurasia, [19] but with relatively high frequency among the Bashkirs of the Perm region (84.0%) and Baymaksky District (81.0%). [20] This marker is present in China and India at frequencies of less than one percent. The table below lists in more detail the frequencies of M269 in regions in Asia, Europe, and Africa.
Distribution of R-M269 in Europe increases in frequency from east to west. It peaks at the national level in Wales at a rate of 92%, at 82% in Ireland, 70% in Scotland, 68% in Spain, 60% in France (76% in Normandy), about 60% in Portugal, [21] 50% in Germany, 50% in the Netherlands, 47% in Italy, [22] 45% in Eastern England, 43% in Denmark and 42% in Iceland. It is as high as 95% in parts of Ireland. It is also found in some areas of North Africa, where its frequency peaks at 10% in some parts of Algeria. [23] M269 has likewise been observed among 8% of the Herero in Namibia. [24] The R-M269 subclade has been found in ancient Guanche (Bimbapes) fossils excavated in Punta Azul, El Hierro, Canary Islands, which are dated to the 10th century (~44%). [25] In western Asia, R-M269 has been reported in 29.2% of Assyrian males from Iran. [26] Haplogroup R1b1 and its subclades in Asia. [27] M269* (xL23) is found at highest frequency in the central Balkans notably Kosovo with 7.9%, North Macedonia 5.1% and Serbia 4.4%. [21] Kosovo is notable in having a high percentage of descendant L23* or L23(xM412) at 11.4% unlike most other areas with significant percentages of M269* and L23* except for Poland with 2.4% and 9.5% and the Bashkirs of southeast Bashkortostan with 2.4% and 32.2% respectively. [21] Notably this Bashkir population also has a high percentage of M269 sister branch M73 at 23.4%. [21] Five individuals out of 110 tested in the Ararat Valley, Armenia belonged to R1b1a2* and 36 to L23*, with none belonging to known subclades of L23. [28] Trofimova et al. (2015) found a surprising high frequency of R1b-L23 (Z2105/2103) among the peoples of the Idel-Ural. 21 out of 58 (36.2%) of Burzyansky District Bashkirs, 11 out of 52 (21.2%) of Udmurts, 4 out of 50 (8%) of Komi, 4 out of 59 (6.8%) of Mordvins, 2 out of 53 (3.8%) of Besermyan and 1 out of 43 (2.3%) of Chuvash were R1b-L23 (Z2105/2103), [29] the type of R1b found in the recently analyzed Yamna remains of the Samara Oblast and Orenburg Oblast. [30]
Especially Western European R1b is dominated by specific sub-clades of R-M269 (with some small amounts of other types found in areas such as Sardinia [21] [31] ). Within Europe, R-M269 is dominated by R-M412, also known as R-L51, which according to Myres et al. (2010) is "virtually absent in the Near East, the Caucasus and West Asia." This Western European population is further divided between R-P312/S116 and R-U106/S21, which appear to spread from the western and eastern Rhine river basin respectively. Myres et al. note further that concerning its closest relatives, in R-L23*, it is "instructive" that these are often more than 10% of the population in the Caucasus, Turkey, and some southeast European and circum-Uralic populations.
In Western Europe it is present but in generally much lower levels apart from "an instance of 27% in Switzerland's Upper Rhone Valley." [21] In addition, the sub-clade distribution map, Figure 1h titled "L11(xU106,S116)", in Myres et al. shows that R-P310/L11* (or as yet undefined subclades of R-P310/L11) occurs only in frequencies greater than 10% in Central England with surrounding areas of England and Wales having lower frequencies. [21] This R-P310/L11* is almost non-existent in the rest of Eurasia and North Africa with the exception of coastal lands fringing the western and southern Baltic (reaching 10% in Eastern Denmark and 6% in northern Poland) and in Eastern Switzerland and surrounds.

In 2009, DNA extracted from the femur bones of 6 skeletons in an early-medieval burial place in Ergolding (Bavaria, Germany) dated to around c. 670 yielded the following results: 4 were found to be haplogroup R1b with the closest matches in modern populations of Germany, Ireland and the USA while 2 were in Haplogroup G2a. [33]
Population studies which test for M269 have become more common in recent years, while in earlier studies men in this haplogroup are only visible in the data by extrapolation of what is likely. The following gives a summary of most of the studies which specifically tested for M269, showing its distribution (as a percentage of total population) in Europe, North Africa, the Middle East and Central Asia as far as China and Nepal.

R-L23* (R1b1a1a2a*) is now most commonly found in Europe, Anatolia, the Caucasus.
R-L51* (R1b1a1a2a1*) is now concentrated in a geographical cluster centred on southern France and northern Italy.
R-L151 (L151/PF6542, CTS7650/FGC44/PF6544/S1164, L11, L52/PF6541, P310/PF6546/S129, P311/PF6545/S128) also known as R1b1a1a2a1, and its subclades, include most males with R1b in Western Europe.
This subclade is defined by the presence of the SNP U106, also known as S21 and M405. [8] [59] It appears to represent over 25% of R1b in Europe. [8] In terms of percentage of total population, its epicenter is Friesland, where it makes up 44% of the population. [60] In terms of total population numbers, its epicenter is Central Europe, where it comprises 60% of R1 combined. [60] See also Haplogroup R-Z18

R1b1a1a2a1a2, better known as R-P312 (or R-S116) is one of the most common types of R-M269 in Europe, alongside R-U106. Myres et al. described it as originating in and spreading from the west of the Rhine basin. [21]
R-P312 has been the subject of significant, ongoing study concerning its complex internal structure.
P312 | |
R-M153
R-M153 is a subclade of R-DF27 that has been found mostly in Basques and Gascons, among whom it represents a sizeable fraction of the Y-DNA pool, [55] [61] though is also found occasionally among Iberians in general. The first time it was located (Bosch 2001 [62] ) it was described as H102 and included seven Basques and one Andalusian.
R-M167 is a subclade of R-DF27 defined by the presence of the marker M167. The first author to test for this marker (long before current haplogroup nomenclature existed) was Hurles in 1999, who tested 1158 men in various populations. [63] He found it relatively common among Basques (13/117: 11%) and Catalans (7/32: 22%). Other occurrences were found among other French, British, Spaniards, Béarnais, and Germans.
In 2000 Rosser et al., in a study which tested 3616 men in various populations [64] also tested for that same marker, naming the haplogroup Hg22, and again it was found mainly among Basques (19%), in lower frequencies among French (5%), Bavarians (3%), Spaniards (2%), Southern Portuguese (2%), and in single occurrences among Romanians, Slovenians, Dutch, Belgians and English.::In 2001 Bosch described this marker as H103, in 5 Basques and 5 Catalans. [62] Further regional studies have located it in significant amounts in Asturias, Cantabria and Galicia, as well as again among Basques. [62] Cases in the Azores have been reported.[ citation needed ] In 2008 two research papers by López-Parra [61] and Adams, [55] respectively, confirmed a strong association with all or most of the Pyrenees and Eastern Iberia.
In a larger study of Portugal in 2006, with 657 men tested, Beleza et al. confirmed similar low levels in all the major regions, from 1.5%–3.5%. [37]
R-L165
This subclade is defined by the presence of the marker S68, also known as L165. It is found in England, Scandinavia, and Scotland (in this country it is mostly found in the Northern Isles and Outer Hebrides). It has been suggested, therefore, that it arrived in the British Isles with Vikings. [65]
R-U152 is defined by the presence of the marker U152, also called S28. [8] Its existence was confirmed by Sims et al. (2007). [59] Myres et al. report this clade "is most frequent (20–44%) in Switzerland, Italy, France and Western Poland, with additional instances exceeding 15% in some regions of England and Germany." [40] Similarly Cruciani et al. (2010) [66] reported frequency peaks in Northern and Central Italy and France. Out of a sample of 135 men in Tyrol, Austria, 9 tested positive for U152/S28. [67] Far removed from this apparent core area, Myres et al. also mention a sub-population in north Bashkortostan, where 71% of 70 men tested belong to R-U152. They propose this to be the result of an isolated founder effect. [21] King et al. (2014) reported four living descendants of Henry Somerset, 5th Duke of Beaufort in the male line tested positive for U-152. [68] Ancient samples from the central European Bell Beaker, Hallstatt and Tumulus cultures belonged to this subclade. [14] [69] [70] Analyzed Iron Age Latins and Etruscans dating between 1000 and 100 BCE belonged primarily to haplogroup R1b-U152 (including the clades L2, Z56 and Z193). [71] [72]
R-L21, also known as R-M529 and R-S145, [8] is most common in Ireland, Scotland and Wales (i.e. at least 25–50% of their male populations. [21] R-L21 has two primary subclades: R-A5846 and R-S552.
R-DF13
A primary subclade of R-S552, R-DF13 – also known as R-S521, R-Z2542 and R-CTS8221 – is one of the most common subclades of R-L21. At least one study estimated that R-DF13 would be found among more than 50% of living Irish males. The following are among the most common subclades within R-DF13.
Haplogroup I (M170) is a Y-chromosome DNA haplogroup. It is a subgroup of haplogroup IJ, which itself is a derivative of the haplogroup IJK. Subclades I1 and I2 can be found in most present-day European populations, with peaks in some Northern European and Southeastern European countries.
Haplogroup G (M201) is a human Y-chromosome haplogroup. It is one of two branches of the parent haplogroup GHIJK, the other being HIJK.
In human genetics, Haplogroup J-M172 or J2 is a Y-chromosome haplogroup which is a subclade (branch) of haplogroup J-M304. Haplogroup J-M172 is common in modern populations in Western Asia, Central Asia, South Asia, Southern Europe, Northwestern Iran and North Africa. It is thought that J-M172 may have originated in the Caucasus, Anatolia and/or Western Iran.
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 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.
Haplogroup R1, or R-M173, is a Y-chromosome DNA haplogroup. A primary subclade of Haplogroup R (R-M207), it is defined by the SNP M173. The other primary subclade of Haplogroup R is Haplogroup R2 (R-M479).
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non-recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). The Y-chromosome accumulates approximately two mutations per generation, and Y-DNA haplogroups represent significant branches of the Y-chromosome phylogenetic tree, each characterized by hundreds or even thousands of unique mutations.
Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup. It is both numerous and widespread among modern populations.
Haplogroup R2a, or haplogroup R-M124, is a Y-chromosome haplogroup characterized by genetic markers M124, P249, P267, L266, and is mainly found in South Asia as well as in Central Asia, Caucasus, West Asia and North Africa / MENA.
The genetic history of Europe includes information around the formation, ethnogenesis, and other DNA-specific information about populations indigenous, or living in Europe.
Haplogroup I-M438, also known as I2, is a human DNA Y-chromosome haplogroup, a subclade of haplogroup I-M170. Haplogroup I-M438 originated some time around 26,000–31,000 BCE. It originated in Europe and developed into several main subgroups: I2-M438*, I2a-L460, I2b-L415 and I2c-L596. The haplogroup can be found all over Europe and reaches its maximum frequency in the Dinaric Alps (Balkans) via founder effect, related to the migrations of the Early Slavs to the Balkan peninsula.
The genetic history of the British Isles is the subject of research within the larger field of human population genetics. It has developed in parallel with DNA testing technologies capable of identifying genetic similarities and differences between both modern and ancient populations. The conclusions of population genetics regarding the British Isles in turn draw upon and contribute to the larger field of understanding the history of the human occupation of the area, complementing work in linguistics, archaeology, history and genealogy.
Haplogroup R1a, or haplogroup R-M420, is a human Y-chromosome DNA haplogroup which is distributed in a large region in Eurasia, extending from Scandinavia and Central Europe to Central Asia, southern Siberia and South Asia.
Haplogroup R1b (R-M343), previously known as Hg1 and Eu18, is a human Y-chromosome haplogroup.
The genetic history of Italy includes information around the formation, ethnogenesis, and other DNA-specific information about the inhabitants of Italy. Modern Italians mostly descend from the ancient peoples of Italy, including Indo-European speakers and pre-Indo-European speakers. Other groups migrated into Italy as a result of the Roman Empire, when the Italian peninsula attracted people from the various regions of the empire, and during the Middle Ages with the arrival of Ostrogoths, Longobards, Saracens and Normans among others. Based on DNA analysis, there is evidence of regional genetic substructure and continuity within modern Italy dating back to antiquity.
In human genetics, Haplogroup R-M167 (R1b1a1a2a1a2a1b1a1) is a Y-chromosome haplogroup which is a subdivision of Haplogroup R-DF27 and the wider haplogroup R-M269 defined by the presence of the marker M167.
The ancestry of modern Iberians is consistent with the geographical situation of the Iberian Peninsula in the South-west corner of Europe, showing characteristics that are largely typical in Southern and Western Europeans. As is the case for most of the rest of Southern Europe, the principal ancestral origin of modern Iberians are Early European Farmers who arrived during the Neolithic. The large predominance of Y-Chromosome Haplogroup R1b, common throughout Western Europe, is also testimony to a sizeable input from various waves of Western Steppe Herders that originated in the Pontic-Caspian Steppe during the Bronze Age.
Genetic studies on Serbs show close affinity to other neighboring South Slavs.
Population genetics is a scientific discipline which contributes to the examination of the human evolutionary and historical migrations. Particularly useful information is provided by the research of two uniparental markers within our genome, the Y-chromosome (Y-DNA) and mitochondrial DNA (mtDNA), as well as autosomal DNA. The data from Y-DNA and autosomal DNA suggests that the Croats mostly are descendants of the Slavs of the medieval migration period, according to mtDNA have genetic diversity which fits within a broader European maternal genetic landscape, and overall have a uniformity with other South Slavs from the territory of former Yugoslavia.
In human genetics, Haplogroup R-DF27 (R1b1a2a1a2a) is a Y-chromosome haplogroup which is a subdivision of haplogroup R-M269 defined by the presence of the marker DF27. Along with R-U152 and R-L21, the lineage is to a significant extent associated with Proto-Celtic, Celtic and later Celtiberian movements.
Given that within the phylogeny of R-M269 (R-PF7562, (R-L51, R-Z2103 is meant) both R-PF7562 and R-Z2103 have their earliest examples in the North Caucasus and steppe to the north, the most likely hypothesis is that the entire R-M269 clade originated there as well, with R-L51 representing a lineage that eventually became highly successful in mainland Europe, R-PF7562 a lineage that did not achieve the prominence of its relatives, and R-Z2103 became highly successful (briefly) as part of the Yamnaya culture and its offshoots
