Genetic History of Haplogroup
Genetic History of Haplogroup R1b The genetic markers that define the ancestral history of those of us in the R1b haplogroup reach back roughly 60,000 years to the first common marker of all non-African men, M168, and follow their lineage to present day, ending with M343, the defining marker of haplogroup R1b. The migration map for R1b highlights our ancestors’ route and shows that members of this haplogroup carry the following Y-chromosome markers: M168 > M89 > M9 > M45 > M207 > M173 > M343 Today, roughly 70 percent of the men in southern England belong to haplogroup R1b. In parts of Spain and Ireland, that number exceeds 90 percent. Our Genetic Sequence Type: Y-Chromosome Haplogroup: R1b (M343) STRs DYS393: 13 DYS439: 12 DYS388: 12 DYS385a: 11 DYS19: 14 DYS389-1: 13 DYS390: 25 DYS385b: 14 DYS391: 11 DYS389-2: 16 DYS426: 12 DYS392: 13 How to Interpret Your Results Above are results from the laboratory analysis of your Y-chromosome. Your DNA was analyzed for Short Tandem Repeats (STRs), which are repeating segments of your genome that have a high mutation rate. The location on the Y chromosome of each of these markers is depicted in the image, with the number of repeats for each of your STRs presented to the right of the marker. For example, DYS19 is a repeat of TAGA, so if your DNA repeated that sequence 12 times at that location, it would appear: DYS19 12. Studying the combination of these STR lengths in your Y Chromosome allows researchers to place you in a haplogroup, which reveals the complex migratory journeys of your ancestors. -
Y-Chromosome Phylogeographic Analysis of the Greek-Cypriot
Voskarides et al. Investigative Genetics (2016) 7:1 DOI 10.1186/s13323-016-0032-8 RESEARCH Open Access Y-chromosome phylogeographic analysis of the Greek-Cypriot population reveals elements consistent with Neolithic and Bronze Age settlements Konstantinos Voskarides1†, Stéphane Mazières2†, Despina Hadjipanagi1, Julie Di Cristofaro2, Anastasia Ignatiou1, Charalambos Stefanou1, Roy J. King3, Peter A. Underhill4, Jacques Chiaroni2* and Constantinos Deltas1* Abstract Background: The archeological record indicates that the permanent settlement of Cyprus began with pioneering agriculturalists circa 11,000 years before present, (ca. 11,000 y BP). Subsequent colonization events followed, some recognized regionally. Here, we assess the Y-chromosome structure of Cyprus in context to regional populations and correlate it to phases of prehistoric colonization. Results: Analysis of haplotypes from 574 samples showed that island-wide substructure was barely significant in a spatial analysis of molecular variance (SAMOVA). However, analyses of molecular variance (AMOVA) of haplogroups using 92 binary markers genotyped in 629 Cypriots revealed that the proportion of variance among the districts was irregularly distributed. Principal component analysis (PCA) revealed potential genetic associations of Greek-Cypriots with neighbor populations. Contrasting haplogroups in the PCA were used as surrogates of parental populations. Admixture analyses suggested that the majority of G2a-P15 and R1b-M269 components were contributed by Anatolia and Levant sources, respectively, while Greece Balkans supplied the majority of E-V13 and J2a-M67. Haplotype-based expansion times were at historical levels suggestive of recent demography. Conclusions: Analyses of Cypriot haplogroup data are consistent with two stages of prehistoric settlement. E-V13 and E-M34 are widespread, and PCA suggests sourcing them to the Balkans and Levant/Anatolia, respectively. -
AFRICAN ORIGIN of NATIVE AMERICAN R1-M173 *Clyde Winters Uthman Dan Fodio Institute, Chicago, Illinois 60643 *Author for Correspondence
International Journal of Innovative Research and Review ISSN: 2347 – 4424 (Online) An Online International Journal Available at http://www.cibtech.org/jirr.htm 2015 Vol. 3 (1) January-March, pp.21-29/Winters Research Article AFRICAN ORIGIN OF NATIVE AMERICAN R1-M173 *Clyde Winters Uthman dan Fodio Institute, Chicago, Illinois 60643 *Author for Correspondence ABSTRACT Controversy surrounds the origin of the y-chromosome R lineages among Native Americans in the United States. Most researchers assume that the occurrence of this gene among Native Americans is the result of European admixture. This view is not supported by the phylogeography of haplogroup R1 which does not correspond to the former territories of the European colonies with the highest population densities. The location of this paternal clade, on the other hand, does match the former centers of Black Native American occupation (and the forced migration of Mongoloid and Black Native Americans into the American Southwest), which suggest that the presence of R1 among Mongoloid Native Americans is the result of Mongoloid-Black Native American admixture. This Indian-African admixture would have been between SSA and the Black Native Americans already living here at the advent of the colonial era mating Mongoloid Native Americans. The African specific R-M173 yDNA form a Sub-Saharan African (SSA) subclade, which in association with the SSA R-M269 subclade in Africa, reveal that there was gene flow from SSA toward mongoloid people in North America, probably during the past 500 years. Keywords: Black Native American, Phylogeography, Clade, Mongoloid, Yamasee, Sub-Saharan African, yDNA INTRODUCTION The phylogeography and origins for haplogroup R1 in the United States has been the subject of intense debate among researchers. -
Possible Correlation Between COVID-19 Contagion and Y-DNA Haplogroup R1b
Possible Correlation between COVID-19 Contagion and Y-DNA Haplogroup R1b Sebastiano Schillaci∗ May 22, 2020 (updated on July 29, 2020) Abstract Here we develop some of the ideas we have first proposed in [1]. In particular, the linear correlation between the initial growth rate of COVID-19 contagion and the average Y-DNA haplogroup percentages in different countries is computed. In the case of haplogroup R1b, a positive correlation with high confidence level is found. Utilizing the maximum R1b percentages in place of the average ones, a more significant result is obtained. Considering an extended R1b data set, correlations with even higher confidence level are found (p-values 3:94 × 10−7 and 2:40 × 10−9, respectively). Repeating the same procedure for the initial growth rate of deaths, similar results are obtained (p-values 9:17 × 10−11 and 2:18 × 10−12, respectively). Furthermore, the correlation of haplogroup R1b with cases and deaths per capita is calculated over a five-month period, obtaining comparable results (e.g. p-value 2:45 × 10−17 on April 10th). The difference between the correlation with maximum R1b percentages and the correlation with average ones is decreasing over time. Finally, assuming the possible involvement of R1b carriers, three scenarios are outlined according to their passive or active role in the spread of the virus.

Received: October 30, 2017 Accepted: November 20, 2017 Available online: November 23, 2017 doi:10.11114/ijsss.v6i1.2809 URL: https://doi.org/10.11114/ijsss.v6i1.2809 Abstract The combination of linguistic and DNA Genealogy data indicates that the aboriginal Europeans, the Y Chromosome haplogroup I people were the Proto-Indo-Europeans and the Proto-Slavic speakers. In contact with newcomers of other language groups mixing took place. Either the newcomers were absorbed into the autochthonous Proto-Slavic community, or the native Proto-Slavic population was so effected by the immigrants that they lost their Slavic identity and formed a language, which remained Indo-European but no longer recognizable as specifically Slavic. The Kurgan Theory and the Pontic Steppe Theory of the Indo-European origin failed completely. The Neolithic Discontinuity Theory theory gives only a part of the necessary explanation. The Paleolithic Continuity Paradigm is superior to them, but it has to be adapted to the data presented by the DNA Genealogy about the timeframe and probable localities of past events. Keywords: DNA Genealogy, origin of humankind, development of humankind, Proto-Indo-Europeans, Proto-Slavs 1. Introduction In December 2016, Mario Alinei and Francesco Benozzo presented an introduction in progress to The Paleolithic Continuity Paradigm for the Origins of Indo-European Languages (Alinei & Benozzo, 2016). -

R1a Subclades and Bronze Age Migrations on the Eurasian Steppes
European Scientific Journal December 2015 /SPECIAL/ edition Vol.2 ISSN: 1857 – 7881 (Print) e - ISSN 1857- 7431 R1A SUBCLADES AND BRONZE AGE MIGRATIONS ON THE EURASIAN STEPPES Csaba Barnabas Horvath, PhD Pátmány Péter Catholic University, Budapest, Hungary Abstract Until recently, our knowledge of the prehistoric world has been blur in many aspects. It was unclear, whether if migrations, conquest, or merely cultural diffusion led from one culture to the other. By the beginning of the 20th century, the introduction of genetics into the study of ancient history gave opportunity for a deeper insight to the prehistoric world. As more and more genetic traces are explored, it becomes more and more possible to identify the routes and time of prehistoric migrations. If we can decode the information hidden in genetic data, a turbulent picture of migrations and conquest between certain prehistoric cultures emerges in front of our eyes. This paper attempts to identify prehistoric migrations in Eastern Europe and Central Asia from the Neolithic to the Bronz Age, based on statistical data of genetic samples. Keywords: Prehistory, migrations, genetics, archeology, Eurasia Introduction This paper aims to identify prehistoric migrations in Eastern Europe and Central Asia from the Neolithic till the Bronze Age, based on genetic material. For this purpose, the paper mainly uses statistical samples of human Y-chromosome haplogroups. The reason why human Y-chromosome haplogroups can be useful for such research is that thes are distinct by the non-recombining parts of Y-chromosome DNA, and this draws a patrilinear phylogenetic tree, and also the age of certain mutations is identifiable. -

Y-Originstm: DNA Test for Paternal Ancestry
Y-OriginsTM: DNA Test for Paternal Ancestry A - Haplogroup A is the oldest and most direct genetic link to “Adam”, the oldest of all haplogroups, and first appeared in Africa about 55,000 years ago. Today, descendants are localized to Southern and Eastern Africa, and are found among the San Bushmen and Khoisan. B - Haplogroup B is only one branch on the tree away from “Adam”, appearing on the African continent about 50,000 years ago. Haplogroup B indicates Sub-Saharan African ancestry, and although it is spread across Africa today, it is found in high percentages in some areas, such as the tropical forests of West-Central Africa, and certain tribes, such as the Pygmy. C – Haplogroup C was initially found in Asia, probably in India where it is most diverse today. It developed about 50,000 years ago. Today we find this haplogroup widely distributed along the Southern Arabian peninsula, India, Mongolia, the Russian Far East, Southeast Asia, Australia and in low frequencies in North America. One subgroup, C2, is considered Polynesian, and C3 is considered to be Native American. D - Haplogroup D first appeared approximately 50,000 years ago in Africa. These ancestors followed the Southern Asian coast in what is known as the Great Coastal Migration, and today we find them in Southeast Asia and the Pacific Rim. Haplogroup D2 is prevalent in both Tibet and Japan. E – Haplogroup E originated in Africa about 50,000 years ago. Today, haplogroup E is divided into three main subgroups. Haplogroups E1 and E2 remained in Africa, but E3 is found in Europe and Western Asia as well as in Africa.
