y-dna

Here are the Eupedia pages that have been translated so far. Anybody with the necessary skills is welcome to volunteer to translate more pages. In French Comment retracer ses origines ancestrales avec un test ADN ? Quel test ADN d'ascendance et de généalogie choisir ? Projet ADN généalogique...

The general consensus has been that Y-chromosomal DNA only contains a few of genes relating to male fertility and does not influence the carrier's appearance, except of course for the male characteristics influenced by testosterone. I have argued before that some Y-chromosomal mutations, in the...

I have long wondered how much of the modern Italian and Greek population descend from slaves imported from other countries. We have no idea at present if their genetic impact was minor (few slaves left descendants), moderate (e.g. 10% or 20% of modern genomes come from foreign slaves) or major...

Just saw this in the news: Was Viking ruler Rollo Danish or Norwegian? This means that we should get the Y-DNA haplogroup of the Viking rulers of Normandy, from Rollo to William the Conqueror. Looking forward to it.

It's been a while since I haven't made any new maps. Here is an attempt to show what Europe, the Near East and North Africa looked like in terms of Y-DNA and mtDNA haplogroups some 10,000 years ago. I delimited the (very) approximate borders of the first cereal/legume farmers in the Fertile...

6 Y-DNA J2 Found in Napoleons Army! "The greatest similarities revealed by Y-haplogroup and haplotype distribution were to populations that live in what are now the Benelux countries or the Alsace, supporting the theory that the individuals indeed were part of Napoleonic troops." Das Leben in...

When G2a Neolithic farmers started advancing from the Near East into Europe, they encountered indigenous hunter-gathering tribes belonging to various haplogroups (C1a2, F, I*, I1, I2a, I2b, I2c, and possibly even H). Interestingly, most of these lineages didn't survive in significant number...

I thought of injecting a little humor into the often contentious and heated topic of y-DNA. Y-DNA jokes ahead, beware. Q: Why does R1b dominate so heavily in the Basque country? A: Because I couldn't make it that far out. Q: Someone asked me if I would help them find a common paternal...

The genetic research is speeding up these days and it shouldn't be long when we have published genomes of many ancient cultures. I think it is time to have a little competition here for bragging rights. Give your best guess. It is a late Neolithic, so we might see same situation as in Hungary...

This poll is intended to get a rough chart of what y-haplogroups are present on this forum. This should preferably be based on testing of your own DNA, but if this has not been done, you may project a likely haplogroup from a family member who would be expected to have the same one as you (e.g...

I have added the samples from Allentoft 2015 and updated the haplogroup frequencies in the section Haplogroups of Bronze Age Proto-Indo-Europeans.

Good day to everyone here! I'm from Italian, Spanish and Portuguese ancestry and I took the family tree dna test to see if my deep roots really come from those places. It turns out that my Y-DNA is R-M269, but as I've been learning, I can't really say from which people that came from, since it...

Hi everyone, I would like you guys to enlighten me on this since it consernes the area that I live on. Most folks consider J1 to be immediatly a typical semithic haplogroup but I have read that that is not true.When I first saw studies conserning J1 has around 3% in my area I doubted of the...

Hello Eupedia, this is my 1st post. I found this forum by searching Google for info on my: Northern Italian (Tuscan) Paternal J1 haplogroup. Any helpful hints? My father, paternal grandfather, and great-grandfather all had Tuscan roots. (Any other TSI: Toscans in Italy, J1?) My paternal...

I an here to ask maciamo to put the portuguese table by regions like spain and italy because the country isn't that homogeneous For example a person from the Algarve is way different from one from trás os montes as a person from trás os montes is different from a person of the minho and etc...

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 -...
