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I have originally made all my Y-DNA frequency maps without showing the political borders of modern countries.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...

I have created a new map combining most Germanic lineages associated with the diffusion Germanic peoples from the Iron Age onwards. These includes Y-DNA haplogroups I1 (except some subclades of Finnish origin), I2-M223, R1a-Z284, R1b-U106, and R1b-L238.

I have started working on a new project: the Genetic History of Italy. The first section includes a summary of the various peoples who came to settle in Italy since the Palaeolithic and the Y-DNA haplogroup that they (probably) brought with them. This section isn't finished yet. I still have...

I was wondering how close do the results have to be to determine a close match. we are all tested positive E1b1b1 E-M35 E-M78- E-V13. Our results are below. Most Distant Ancestor of Country of Origin are different. Italy- 13 25 13 10 16-21 11 12 12 13 11...

Here is the breakdown of J2 subclades by province based on the recent study by Boattini et al.. North Italy In Cuneo, south-west Piedmont, 2 out of 30 samples are J2 (6.5%), both J2a*. In Savona/Genova, central Liguria, 7 out of 50 samples are J2 (14%), among which three J2a*, two J2a2-M67...

The new paper by Boattini et al. is the first Italy-wide study to report haplogroup T separately from K (along with Brisighelli et al. 2012, which reported it as K2). It therefore provides valuable insight into this little studied haplogroup. The sample sizes for each province tested is...

Haplogroup I1 is a marker of Germanic migrations to Italy. The Ostrogoths, Vandals, Lombards, Franks and Normans all left some I1 lineages behind them. The distribution of I1 is fairly homogeneous all over Italy, usually ranging from 1 to 5%. I had a look at the new study by Boattini et al. to...

Haplogroup J1 is found at relatively low frequencies in Europe, except in Italy and Greece. The new study by Boattini et al. provides new insight into the distribution of J1 and its subclades in Italy. The highest concentration is found in Agrigento (12%) in southwest Sicily, most probably due...

I have calculated the provincial percentages of G2a in Italy based on the recent study by Boattini et al. The new data significantly alters the known distribution of G2a across the peninsula. Extremely high frequencies (20-25%) were observed in Abruzzo, Molise, Basilicata and Calabria. The...

Here is the breakdown of E1b1b subclades by province based on the recent study by Boattini et al.. North Italy In Cuneo, south-west Piedmont, 2 out of 30 samples are E1b1b (6.5%), among which one E-V13 (3.5%) and one E-V65 (3.5%). In Savona/Genova, central Liguria, 8 out of 50 samples are...

I have counted the samples for each R1b subclade in the new study of Italian Y-chromosomes by Boattini et al. and calculated the percentages for R1b for each province. The two most interesting R1b subclades in Italy are R1b-U152, which I believe to be associated with the Italic migrations, and...

Full Genomes Corp is now offering what I believe is the world's first commercial full genomic sequence of the Y-chromosome. The test is destined at the genetic genealogy community and will report the person's haplogroup, and analysis of both SNP's and STR's, including private SNP's. This should...

A new article in Nature revealed that Carsten Pusch from the University of Tübingen managed to sequence the DNA of an ancient Egyptian mummy. Sadly the article doesn't give more information about the identity or age of the mummy, but there is a fleeting mention that the man belonged to...

Yaan pointed me to this 2012 paper by Mrsic et al. They tested the Y chromosomes of 1100 Croatian men, 220 for each of the five regions. This allowed me to recalculate the haplogroup frequencies more accurately. So far, the small studies by Pericic et al. (2005) and Battaglia et al. (2008) only...

PLOS ONE just released Y-Chromosome Diversity in Modern Bulgarians: New Clues about Their Ancestry by Karachanak et al. Bulgaria was relatively undersampled to this day. This study, sampling 808 lineages from each of the 9 Bulgarian provinces, will provide valuable new insight, especially since...

A very exciting new paper was released yesterday, confirming the announcement four months ago that the common ancestor to all human male lineages lived much longer ago than what believed so far. An African American Paternal Lineage Adds an Extremely Ancient Root to the Human Y Chromosome...
