At present, ancient Y-DNA tests have only confirmed the presence of haplogroups G2a and F among the remains of Neolithic farmers from the Linear Pottery culture (LBK) in Central Europe. Elsewhere, only G2a and E-V13 have been found, besides the Mesolithic lineage I2a. Most people now agree that...

According to the genetic genealogy testing company BritainsDNA, about 50% of the 70,000 people who carry the surname Stuart or Stewart in the UK or Ireland descend from the Royal House of Stewart. The company tested the descendants of James Stewart, 5th High Steward of Scotland (c.1243-1309)...

I am starting to get annoyed by the number of useless studies published recently in the field of population genetics that do not tell us anything that we didn't already know, and do not provide any worthwhile new data (e.g. Pickrell et al. 2014, Sverrisdóttir et al. 2014, Pierron et al. 2013...

I have recently proposed a novel theory regarding the origins of haplogroup R1b. I believe that R1b1 (P25) people might have been among the first people to domesticate cattle in eastern Anatolia and northern Mesopotamia/Syria during the Pre-Pottery Neolithic period. I suggested that the P297...

A recent paper on Madagascar Y-DNA and mtDNA made me realise that Y-haplogroups J1 and T1 probably both spread from the northern Zagros after having become nomadic herders during the Pre-Pottery Neolithic. Both haplogroups are usually found together in Europe, in the Arabian peninsula, Egypt...

Mal'ta boy had autosomal genes present in populations with Y-haplogroups M, P, Q & R Two weeks ago, Raghavan et al. published a paper on the genome of an Upper Palaeolithic Siberian individual, known as the Mal'ta boy. It is by far the oldest human genome tested to date. The authors reported...

What R1b-subclade does most of Bosnians belonging to? The Italo-Celtic branch (S28/U152), Balkanic branch R1b-L23 or to the Continental Germanic branch R1b-S21 (U106)? According to this map, 10-15% of Bosniaks in Bosanska Krajina (Northwestern Bosnia) is belonging to the Italo-Celtic branch...

The Brabant DNA Project, with 1000+ members from all Belgium and a few from bordering areas (especially North Brabant in the Netherlands), has re-tested the Y-DNA of all R1b members for the following subclades. - Under U106: Z18, Z381, L48, and U198 - Under P312: L21/M529 and Z195/Z196 - Under...

The human Y chromosome contains only 86 genes, compared to 20,000 genes on the 45 other chromosomes. While most mutations defining Y-DNA haplogroups lie in non-coding regions of the Y chromosome, a few other take place in actual genes. One of the most important among these genes is SRY...

After E-V13 it was only natural that I should follow with the map of J2b, the other major South Balkanic lineage with Neolithic ties. The distribution is actually quite similar to E-V13, apart from a lower incidence in Slavic countries, but that may just be because E-V13 is found at a ratio of...

I have just updated the Y-DNA frequencies for Denmark, Sweden and Norway. The sample sizes are now respectively 613, 1323 and 2826, including the FTDNA projects for each country. I didn't use the data from the Scandinavian DNA Project and the Viking DNA Project as I didn't feel like checking for...

I am currently revising the Y-DNA frequencies in Eastern Europe. The current data for Macedonia includes the following papers: Pericic 2005, Bosch 2006, Noveski 2009 and Trivodalieva 2010. I have found one more study by Spiroski et al. (2005), which tested 150 samples. Unfortunately they only...

I have added new populations in the Y-DNA tables: the island of Gotland in Sweden, the Saami (Finland+Sweden+Norway), and the six main ethnic groups of the Volga-Ural region in Russia: the Chuvashs, Komi, Mari, Mordvins, Tatars, and Udmurts. Gotland distinguishes itself by its extremely high...

Bonjour à tous. Des années que je navigue sur ce site. Une mine d'information et trop peu d'articles en français malheureusement. Mon anglais est trop sommaire et je n'ai jamais pu trouver de réponse à une question que je me pose. On fait associer en génétique des populations certains YDNA...

Isn't there some genetic research of the Montenegrin population? If there is, couldn't the adminstrator write those down and include them on the list of the Y-DNA haplogroups in "Distribution of European Y-chromosome DNA (Y-DNA) haplogroups by country in percentage"?

Spain and Portugal are fairly well studied countries for Y-chromosomal lineages. Unfortunately no study so far has tested for the Germanic S21/U106 subclade of R1b, and few papers even distinguish subclades of I (those who did only tested for I2a1a-M26). I have analysed the raw data from Adams...

I have originally made all my Y-DNA frequency maps without showing the political borders of modern countries. I only added borders for the maps of haplogroup I, R1 and EGJT. I could easily add borders though. As I prefer to have only one version of each map online, I would like to ask first if I...

I have updated my article on the Genetic History of Italy, adding a section arguing that the Romans were predominantly R1b-U152 (S28) based on the geographic distribution colonies founded by the Roman inside Italy. I have created a map showing the locations of Roman colonies and U152 frequencies.

Eastern Anatolia has played a major role in the development of the Neolithic, Chalcolithic, Bronze Age and Iron Age. It is also one of the most complex region for population geneticists to disentangle due to its high level of genetic diversity. In this thread I would like to propose an answer...

I have created a map showing all Italo-Celtic subclades of R1b, namely everything downstream of S116 (P312). That represents most of the European R1b minus the Greco-Etruscan R1b-L23, the Germanic R1b-U106 and R1b-L238, and the Proto-Celto-Germanic L11, L51 and L150. S116 includes subclades...
