y-dna

I am working on a new page dedicated to the genetic history of the Britain & Ireland. I have almost finished. I had to calculate the regional Y-DNA frequencies and revise all the maps based on the finer resolution that I obtained. Please feel free to provide your feedback and let me know if you...

I have created a new map of R1a-M458, a lineage which I associate with the Corded Ware expansion and which peaks in West Slavic countries today. The Underhill et al. 2014 paper provided a rough distribution map of R1a-M458, but I wasn't satisfied by its accuracy (it is auto-generated, not...

Checking the Rose DNA Project, I found one member (#310947) whose most distant paternal ancestor is listed as being Cornelius Geldersman via his grandson Claes van Roosevelt (1626-1658). This happens to be the ancestor of the two Roosevelt presidents as this genealogy shows. The Ysearch ID is...

I was compiling a list of common Ashkenazi Jewish surnames and their dominant Y-haplogroups when I found the Oppenheimer DNA Project. The original Oppenheimer family from the Rhineland-Palatinate appears to have belonged to Q1b. I verified the genealogy of the American theoretical physicist J...

Using surname projects at FamilyTreeDNA, I have listed the dominant Y-DNA haplogroup for a series of common Jewish family names. Common alternative spellings are mentioned in brackets. Haplogroups that make up at least 50% of the total surnames in the project are in bold. Biblical lineages -...

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"?
