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. A more compact cluster of Near/Middle Eastern samples is also resolved in the network. Evaluation of Y-chromosomal STRs: a multicenter study. For the human mtDNA haplogroup, see. [21] In a study of 936 Indians, haplogroup G made up less than 1% of the sample and was completely absent in the tested Northwestern Indian population. Y-chromosomal diversity in Lebanon is structured by recent historical events. You are using a browser version with limited support for CSS. Dulik MC, Zhadanov SI, Osipova LP et al. The Caucasus as an asymmetric semipermeable barrier to ancient human migrations. The corresponding coalescent estimate for M377 is 5600 years ago (Supplementary Table S4). This group has been linked with the Crypto-Jewish population which fled to the island during the time of the Spanish Inquisition, of which a significant portion are identifiable as G-Z725 (DYS388=13). (Previously the name Haplogroup S was assigned to K2b1a4. G2a was found in medieval remains in a 7th- century CE high-status tomb in Ergolding, Bavaria, Germany, but G2a subclades were not tested.[34]. Herein . These patterns have been related to different migratory events and demographic processes.2, 10, 11, 14, 15, 16. Achilli A, Olivieri A, Pala M et al. Specifically, we intersected these criteria by applying the following filters. Forensic Sci Int-Gen 2007; 1: 287290. The complexity is apparent in both the phylogenetic resolution and geographic patterning within hgs G and J2a. G1 is possibly believed to have originated in Iran. Network of 248 samples P303 derived from Supplementary Table S3. Haplogroup definition, a set of similar haplotypes inherited together, or a group who shares a set of similar haplotypes, used to understand genetic lineages. This skeleton could not be dated by radiocarbon dating, but other skeletons there were dated to between 5,100 and 6,100 years old. Eur J Hum Genet 2010; 18: 348353. Haplogroup K2e (K-M147) was previously known as "Haplogroup X" and "K2a" (but is a sibling subclade of the present K2a). contracts here. The genetic legacy of Paleolithic Homo sapiens sapiens in extant Europeans: a Y chromosome perspective. G-M201 is most commonly found among various ethnic groups of the Caucasus, but is also widely distributed at low frequencies among ethnic groups throughout Europe, South Asia, Central Asia, and North Africa. The overall coalescent age estimate (Supplementary Table S4) for P303 is 12600 years ago. In human genetics, Haplogroup G-P303 ( G2a2b2a, [2] formerly G2a3b1) is a Y-chromosome haplogroup. Included within G-L91 are some men with double values for STR marker DYS19, but there are also G2a2 men with this finding who are not L91+. You belong to a subgroup of haplogroup G (G-M201), The Caucasus Mountaineers, and your oldest. Moreover, the accuracy and validity of the evolutionary rate has been independently confirmed in several deep-rooted Hutterite pedigrees.34 Furthermore pedigree rate-based estimates cannot be substantiated, as they are often inconsistent with dateable archeological knowledge, for example, as clearly illustrated regarding the peopling of the Americas.35 Coalescent times based on 10 STR loci (DYS19, DYS388, DYS389I, DYS389b, DYS390, DYS391, DYS392, DYS393, DYS439, DYS461-TAGA counts) and the median haplotypes of specific hg G sub-haplogroups are presented in Supplementary Table S4. A subset of 693 samples was typed for short tandem repeats of Y-chromosome (Y-STRs) using the 17 STR markers in the Applied Biosystems AmpFlSTR Yfiler Kit according to manufacturer recommendations. Haplogroup G1 is a primary subclade of haplogroup G . Vernesi C, Caramelli D, Dupanloup I et al. Conversely, hg G is present in Northeast Caucasus only at an average frequency of 5% (range 019%). A plot of the sub-clades included in the principal component analysis (Figure 3b) indicates that the clustering of the populations from NW Caucasus is due to their U1* frequency, whereas L497 lineages account for the separation of central Europeans. It is a branch of Haplogroup F (M89), and is theorized to have originated, according to the latest thinking, in the Near East or Southern Asia, likely in the region that is now northern India, Pakistan, and Afghanistan. This is achieved by comparing the haplotypes through the STR markers. The emergence of Y-chromosome haplogroup J1e among Arabic-speaking populations. 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. The extreme rarity of G-M377 in northern Pakistan could indicate that G2b in this area originates outside the region and was brought there in the historic period, perhaps from further west (Pakistan was part of both the Achaemenid Persian Empire, conquered by Alexander the Great, and then formed a part of the Greco-Bactrian Kingdom). Article We emphasize that our assessments are based solely on contemporary DNA distributions rather than actual prehistoric patterns. Because SNPs provide the most reliable method of categorization, each is allowed to represent an official G category. In Egypt, studies have provided information that pegs the G percentage there to be between 2% and 9%. Finally, to the east, G2a3a-M406 has an expansion time of 8800 years ago in Iran, a time horizon that corresponds to the first Neolithic settlements of the Zagros Mountains of Iran. King RJ, DiCristofaro J, Kouvatsi A et al. [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. PAU thanks Professor Carlos D Bustamante. Gene pool structure of Eastern Ukrainians as inferred from the Y-chromosome haplogroups. Whereas the presence of Mideastern mtDNA in Tuscany43 supports the model of early Iron Age migrants from Anatolia (putative Etruscans) colonizing Central Italy,44 the occurrence of the G2a3b1c-L497 lineage in Italy is most likely associated to migratory flows from the north. Battaglia V, Fornarino S, Al-Zahery N et al. An assessment of the Y-chromosome phylogeography-based proposal that the spread of G2a-L497 chromosomes originated from Central Europe could be achieved by typing this SNP in the Holocene period human remains from Germany31 as well as those from France and Spain.45, 46 Certainly, Y chromosome represents only a small part of human genome and any population-level interpretation of gene flow in this region would have to be supported by genome-wide evidence. The formula for the coalescence calculations is as follows: Age=25/1000 ASD0/0.00069. Hum Hered 2006; 61: 132143. Eur J Hum Genet 20, 12751282 (2012). G1-M285, previously described in the Iranian population . G2a2b2a is also found in India. 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. Differential Y-chromosome Anatolian influences on the Greek and Cretan Neolithic. So far all G2a1 persons have a value of 10 at STR marker DYS392. L223 is found on the Y chromosome at rs810801 and 6405148 with a mutation from C to G. L223 was first identified in samples at 23andMe in 2009 but proved problematic as an individual test, the first successful results being reported at Family Tree DNA in late 2011 under its assigned L223 label.

Am J Hum Genet 2008; 82: 236250. See: Poznik. 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. They are found only in tiny numbers elsewhere. In the Americas, the percentage of haplogroup G corresponds to the numbers of persons from Old World countries who emigrated. (2000) suggested 17,000 years ago. Barac L, Pericic M, Klaric IM et al. Sims LM, Garvey D, Ballantyne J : Improved resolution haplogroup G phylogeny in the Y chromosome, revealed by a set of newly characterized SNPs.

Hum Genet 2004; 114: 127148. The identification of a new SNP can necessitate renaming of one or more categories. G-M406* (G2a2b1*; previously G2a3a*) and its subclades seem most commonly found in Turkey and the coastal areas of the eastern Mediterranean where it can constitute up to 5% of all makes and 50% of haplogroup G samples. The Sea Peoples, from cuneiform tablets to carbon dating. G-P303*, also known as G2a2b2a* (previously G2a3b1*), and its subclades are now concentrated in southern Russia and the Caucasus, as well as, at lower levels, other parts of Europe and South West Asia, especially an area including Turkey, Iran and the Middle East where G2a2b2a may have originated. Origin. The SNP L177 (a.k.a. Spatial autocorrelation analysis was carried out to assess the presence/absence of clines regarding informative G sub-haplogroups. The G-M286 subclade (M286+) is small compared with G-L91. A separate study on the Argyns found that 71% of males belong to G1. 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. Distinguishing the co-ancestries of haplogroup G Y-chromosomes in the populations of Europe and the Caucasus. To accommodate for variability in sample sizes and hg G content, haplogroup diversity was calculated using the method of Nei37 only in the 52 instances when total population sample size exceeded 50 individuals and 5hg G chromosomes were observed. Eur J Hum Genet 2003; 11: 535542. Similarly, G-P16 and G-M377 networks were created using 104 P16-derived 19-locus haplotypes and 61G-M377-derived 9-locus haplotypes, with both groups representing European, Near/Middle Eastern and central/west Asian populations. Hum Genet 2009; 126: 707717. The mutations involved may be complicated and difficult to interpret.
