[23] About 6% of the samples from Sri Lanka and Malaysia were reported as haplogroup G, but none were found in the other coastal lands of the Indian Ocean or Pacific Ocean in Asia. The DYS391 marker has mostly a value of 10, but sometimes 11, in G2a2b1 persons, and DYS392 is almost always 11. In the Russian North Caucasus the Kabardinian and Ossetian populations are also notable for high rates of G-M201. The authors declare no conflict of interest. Haplogroup F is the parent of haplogroups from G to R; however excluding these common haplogroups, the minor clades F*, F1, and F2, seem to appear in the Indian continent [68]. Correspondence to [citation needed] The hg G-U1 subclade is characterized by several sub-clusters of haplotypes, including a more diverse cluster mostly represented by Caucasus populations. You belong to a subgroup of haplogroup G (G-M201), The Caucasus Mountaineers, and your oldest. The complexity is apparent in both the phylogenetic resolution and geographic patterning within hgs G and J2a. Although hg G1 frequency distribution, overall, extends further eastward as far as Central Asian Kazakhs (present even among Altaian Kazakhs38 with identical STR haplotypes compared with the main Kazakh population), it is virtually absent in Europe. [4], Two scholarly papers have also suggested an origin in the Middle East, while differing on the date. These latter labs also made use of raw data results reported by individuals tested for about 2,000 SNPs at 23andMe to provide new L or S-designated SNP tests. Haplogroup G2a1 (also known as G-FGC753 and previously as G-L293) and its subclades represent the majority of haplogroup G samples in some parts of the Caucasus Mountains area. Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language. 25 and 0.00069 denote the assumed average generation time in years and the effective mutation rate, respectively, and 1000 is used to convert the result of the equation (into thousands of years). The SNP L497 encompasses these men, but most G-L497 men belong to its subclade G-Z725, also known as G-DYS388=13. A clade of closely related Ashkenazi Jews represent virtually all G2b persons, with just three other G2b haplotypes having been reported so far: one Turk from Kars in northeast Turkey near Armenia, one Pashtun, and one Burusho in Pakistan. This video explains the migration route of Y-chromosome haplogroup G and the countries where it can be found today. Hammer MF, Behar DM, Karafet TM et al. The highest frequencies of haplogroup G appear in the Caucasus region; however it also shows significant frequencies in the Mediterranean areas and the Middle East [69,70]. Circles represent microsatellite haplotypes, the areas of the circles and sectors are proportional to haplotype frequency (smallest circle corresponds to one individual) and the geographic area is indicated by color. White PS, Tatum OL, Deaven LL, Longmire JL : New, male-specific microsatellite markers from the human Y chromosome. Herein . Provided by the Springer Nature SharedIt content-sharing initiative, European Journal of Human Genetics (2021), European Journal of Human Genetics (2020), European Journal of Human Genetics (Eur J Hum Genet) It has been found in Mexican mestizos. [43] L240 was identified in 2009. EKK thanks the Russian Academy of Sciences Program for Fundamental Research Biodiversity and dynamics of gene pools, the Ministry of Education and Science of the Russian Federation for state contracts P-325 and 02.740.11.07.01, and the Russian Foundation for Basic Research for grants 04-04-48678- and 07-04-01016-. (2000) suggested 17,000 years ago. Drawing the history of the Hutterite population on a genetic landscape: inference from Y-chromosome and mtDNA genotypes. . Semino et al. The highest reported concentration of G1 and its subclades in a single country is in Iran, with next most frequent concentrations in neighboring countries to the west. G2a1a persons also typically have higher values for DYS385b, such as 16, 17 or 18, than seen in most G persons. Haplogroup L2b1a is a branch on the maternal tree of human kind. In the Americas, the percentage of haplogroup G corresponds to the numbers of persons from Old World countries who emigrated. Eur J Hum Genet 2008; 16: 374386. In Russia, Ukraine and Central Asia, members of various ethnic minorities and/or residents in particular localities possess G-M201 at its highest levels in the world even though the average rate at the national level is about 1% or less. [2], In 2012, a paper by Siiri Rootsi et al. [39], Haplogroup G-M377 has been found at a frequency of 60% out of a sample of five Pashtuns in the Wardak region of Afghanistan. There are distinctive Ashkenazi Jewish and Kazakh subclades based on STR marker value combinations. Although the phylogenetic resolution within hg G has progressed,1, 17 a comprehensive survey of the geographic distribution patterns of significant hg G sub-clades has not been conducted. In the Near/Middle East, the highest P303 frequency is detected among Palestinians (17.8%), whereas in Europe the frequency does not exceed 6%. (b) Principal component analysis by hg G sub-clades: (A) M285, P20, P287, P15, L92 P16, M286, M485, P303, U1, L497, M527, M406, Page19, M287 and M377 sub-haplogroups with respect to total M201. No clinal patterns were detected suggesting that the distributions are rather indicative of isolation by distance and demographic complexities. Am J Hum Genet 2003; 72: 313332. Furthermore, markers Page94, U5, U8 and L30 were typed in contextually appropriate samples to establish the position of the five new markers within the phylogeny. Semino et al. The mutations involved may be complicated and difficult to interpret. ISSN 1476-5438 (online) To obtain PLoS Biol 2010; 8: e1000536. The genome-wide structure of the Jewish people. Several G-PF3359 subclades, based on shared STR markers, probably exist. The highest percentage of G-P303 persons in a discrete population so far described is on the island of Ibiza off the eastern Spanish coast. Y-chromosomal evidence of the cultural diffusion of agriculture in Southeast Europe. Another notable feature is its uneven distribution. Y-DNA haplogroups are useful to determine whether two apparently unrelated individuals sharing the same surname do indeed descend from a common ancestor in a not too distant past (3 to 20 generations). Should any man with the P15 mutation test negative (ancestral) for any of these or vice versa, that finding would be the basis of a new G2a category. In the G2a3b-P303 network (Figure 4), there are several region-specific clusters, indicating a considerable history for this SNP. The L141 mutation is found on the Y chromosome at 2948607. His male-line descendants appear to remained rooted in the region for tens of thousands of years while the Ice Age was in full swing. The Levant versus the Horn of Africa: evidence for bidirectional corridors of human migrations. This is achieved by comparing the haplotypes through the STR markers. However, no clinal patterns were detected in the spatial autocorrelation analysis of the five sub-haplogroup frequencies with distance, suggesting that the distributions are not clinal but rather indicative of isolation by distance and demographic complexities. Kayser M, Caglia A, Corach D et al. Phylogenetic relationships of studied binary markers within haplogroup G in wider context of M89-defined clade. Haplogroup H dominates present-day Western European mitochondrial DNA variability (>40%), yet was less common (~19%) among Early Neolithic farmers (~5450 BC) and virtually absent in Mesolithic . Although not exceeding 3% frequency overall, haplogroup G1-M285 reflects a branching event that is phylogenetically equivalent to the more widespread companion G2-P287 branch in the sense that both branches coalesce directly to the root of G-M201. The expansion time of G-M406 in Anatolia is 12800 years ago, which corresponds to climatic improvement at the beginning of the Holocene and the commencement of sedentary hunter-forager settlements at locations, such as Gobekli Tepi in Southeast Anatolia, thought to be critical for the domestication of crops (wheat and barley) that propelled the development of the Neolithic. PLoS One 2011; 6: e20232. The double 19 value situation is not seen in the G2a1 and G2a3 subclades. The National Geographic Society places haplogroup G origins in the Middle East 30,000 years ago and presumes that people carrying the haplogroup took part in the spread of the Neolithic Two scholarly papers have also suggested an origin in the Middle East, while differing on the date. Am J Hum Genet 2008; 82: 236250. Hg G also occurs at frequencies ranging from 5 to 15% in both the rest of Near/Middle East and southern European countries (especially Italy and Greece), with a decreasing frequency gradient towards the Balkans and northern Europe. Important caveats to consider include the fact that Td is sensitive to authentic rare outlier alleles and that multiple founders during population formation will inflate the age estimate of the event. (2000) suggested 17,000 years ago. The non-clustering paraphyletic, hg G sub-group P303* residuals consist of samples from Near/Middle Eastern, Caucasian and European populations. Origin. In other words, these mutations are so unique that they could only come from other cells with the same mutations. [7], (Subclades here conform to the Y-DNA SNP definitions used by ISOGG In 2012, several categories found only in one man in research studies were removed from the ISOGG tree causing some renaming. In human genetics, Haplogroup G (M201) is a Y-chromosome haplogroup. SR thanks the Estonian Science Foundation for grant 7445 and M Metspalu for grant 8973. This is likely due to a local founder effect.[40]. However, interpretations based on simple haplogroup frequency clines do not recognize underlying patterns of genetic diversification. Differential Y-chromosome Anatolian influences on the Greek and Cretan Neolithic. See more. The highest frequency values for P303 are detected in populations from Caucasus region, being especially high among South Caucasian Abkhazians (24%) and among Northwest (NW) Caucasian Adyghe and Cherkessians39.7% and 36.5%, respectively. Internet Explorer). The emergence of Y-chromosome haplogroup J1e among Arabic-speaking populations. Hg G is very frequent in NW Caucasus and South Caucasus, covering about 45% of the paternal lineages in both regions2 in this study. These two reported Pakistani G-M377 haplotypes are quite divergent from the Ashkenazi Jewish clade, and therefore do not at all indicate a recent common origin. In addition, K-Y28299, which appears to be a primary branch of K-M2313, has been found in three living individuals from India. Here we present the haplogroup frequency distribution and STR variation of 16 informative G sub-clades by evaluating 1472 haplogroup G chromosomes belonging to 98 populations ranging from Europe to Pakistan. The identities of the specific 19 loci that define the STR haplotypes are reported in Supplementary Table S3 and Figure 4 legend. (a) Principal component analysis by population. Age: About 7,800 years ago Origin: Eurasia Y-Haplotree. [26][27] Among the Druze mostly residents of Israel 10% were found to be haplogroup G.[28], Around 10% of Jewish males are Haplogroup G.[citation needed], In Africa, haplogroup G is rarely found in sub-Saharan Africa or south of the horn of Africa among native populations. There are multiple SNPs which so far have the same coverage as P15. It encompasses a small group of Hispanic men who also so far all have the odd value of 13,21 at the YCA marker. Geographic spread patterns of the P303-derived groups defined by L497, U1 and P15(xP303)-derived P16 and M406 lineages, all of which achieve a peak frequency of at least 10%, are presented in Figures 2bf, respectively. Use the Previous and Next buttons to navigate the slides or the slide controller buttons at the end to navigate through each slide. Although compared with G1-M285, the phylogenetic level of P303 (Figure 1) is shallower but its geographic spread zone covers the whole hg G distribution area (Figure 2b). Evaluation of Y-chromosomal STRs: a multicenter study. The genetic heritage of the earliest settlers persists both in Indian tribal and caste populations. It is one of two branches of the parent haplogroup GHIJK, the other being HIJK . The presence of hg G was first reported in Europe and Georgia5 and later described in additional populations of the Caucasus.6 Subsequently, several data sets containing hg G-related lineages have been presented in studies of different European populations7, 8, 9, 10 and so on, as well as studies involving several Middle Eastern and South Asian populations.4, 11, 12, 13, Hg G, together with J2 clades, has been associated with the spread of agriculture,5 especially in the European context.
