I previously posted about
V13/CTS5856. Since then I've used the Genographic project samples to look deeper in the distribution of V13/CTS5856. The analysis of that group is too specific for this board, but I also looked at the distribution of all groups in Greece, and that might be of interest here. I picked Greece since V13/CTS5856 is the major haplogroup there, and the peculiar geography and well documented history of Greece might provide some insight in the migration of V13 and it's timing.
All what follows is based on data from the Genographic project ("The National Geographic Society’s Genographic Project") unless otherwise specified, with many thanks to them for their work and their kind permission for me to access to their database.
I queried the Genographic project's database for all demographic fields containing "Greece" or "Greek". I selected all samples that had a male Greek ancestry (and excluded Vlach, Gypsy and Arvanite samples). Limiting to those with Y-DNA info I had 1530 samples. I used the different demographic fields to subdivide this 1530 samples in a number of regions. The samples belong to different phases of the project. The next statistics are based on the main one, containing 1119 samples. The following were the totals over these 1119, and the totals over the samples from the other phases that I mapped to the SNP's of the main phase (total n=1530). I have to stress this is not a representative sample of Greece as a whole, as regions from where there was a lot of emmigration are obviously favored, most Genographic participants were descendants of emmigrants (especially to the US).
Levels over all of Greece:
C-M130 0,4%
E-M215 24,7%
G-M201 8,1%
I-M170 2,3% (= I2-L596 or I2-Y10705)
I1-M253 2,2%
I2-P37 8,4%
I2-M223 1,5%
J1-M267 4,5%
J2-M172 17,3%
L-M20 1%
N-M231 0,5%
Q-L232 0,6%
R1a-L63 9,9%
R1b-M343 15%
T-M170 3,1%
Some observations per group over the distribution in Greece:
For the record: Northern Aegean is mainly Lemnos and Lesbos, Central Aegean is Chios, Icaria, Samos and the Cyclades.
C: present in small levels in Cyprus, Asia minor and the Pelopenesos
E-M215: significantly higher in Thessaly (32%), the Dodecanese (32%) and the Peloponessos (30-35%) with the exception of Arcadia, where it's only 24%. It's close to the mean in Asia minor (25%), Cyprus (25%), the Ionian islands (26%) and, maybe surprising, Epirus (28%). Slightly lower on the central Aegean Islands (22%), the northern Aegean Islands (20%), Athens (18%) and, maybe again surprising, Greek Macedonia (16%) and Thesaloniki (22%). It's significantly lower in Pontic Greeks (12%) and Crete (12%). In the detailed results the split is: 16,4% V13, 1% V32, 1% V22, 4,8% Z827. It's harder to judge the distribution of the subgroups as the totals are quite small for that.
G-M201: Higher in Euboea and the Sporades (20%), Pontic Greeks (19%), the Dodecanese (18%), Crete (13%), the Ionian Islands (11%) Asia Minor (11%), North Aegean Islands (12%), Cyprus (16%). Lower in Thessaly (4%), Athens (4%), central Aegean islands (2%), on the Peloponessos (2-6%), Central mainland (2%), Epirus (3%).
I-M170: Significantly higher on Crete (9%) and in Thessaly (6%)
I1-M253: Higher on the Ionian Islands (9%). The Ionian samples are mostly from Korfu, this might be related to the medieval occupation by Normans from the Sicilian kingdom.
I2-P37: Low on Cyprus (1%), Crete (4%), Athens (6%), the central Aegean Islands (4%), Pontic Greeks (0%), Dodecanese (4%), High in Arcadia (21%), Greek Macedon (14%), Thessaly (13%), Epirus (20%), the Northern Pelopenessos (25%), Thesaloniki (14%), Asia Minor (11%). This seems to suggest a Slavic origin. The I2 is dominated by F3145 (L621) in the detailed samples (73%)
J1-M267: Higher in Pontic Greeks (12%), the Dodecanese (11%), central Aegean Islands (8%), Istanbul (11%), the central mainland (10%), on Cyprus (10%), in Arcadia (6%) and Crete (6%). It's low in Asia minor (2%), The peloponessos besides Arcadia (0%), Greek Macedonia (1%), Epirus (0%), Northern Aegean Islands (4%)
J2-M172: Low in Thessaly (9%), Central mainland (7%), Greek Macedonia (10%), Dodecanese (11%), Epirus (13%), the Ionian islands (13%), higher in Cyprus (23%), Crete (29%), Athens (20%), Arcadia (23%), Pontic Greeks (26%), Istanbul 22%, Thesaloniki (25%) and the Central Aegean islands (27%)
L-M20: A little highter in Asia Minor and the Pontic Greeks.
R1a-L63: Much lower in Asia minor (4%), Cyprus (6%), Crete (5%), Arcadia (6%), the Pontic Greeks (5%), Dodecanese (0%) and the northern Pelopenessos (0%). It's high in Greek Macedonia (17%), Thessaly (15%), Epirus (13%), Central mainland (14%), Athens (14%), Thesaloniki (14%), the central Aegean Islands (12%) and the Southern Pelopenessos (18%). Looking at this, the subclades from more recent phases, and comparing to the FTDNA R1a project, it seems likely most of this R1a is Slavic in origin. The outlier in the central Aegean is partly due to samples from Ikaria, and is probably the result of migration in the 15th-16th century. From the limited deeper phase there's 8,3% Z93, 25% from the fairly recent CTS11962, 8,3% from L784, 37,5% from CTS3402, 12,5% from CTS1211 (xCTS3402). A quick check with the FTDNA R1a project reveals that there also L1029/CTS11962 and CTS1211 represent the largest share of Greek samples. It's a bit strange that on the pelopenessos R1a seems to complement I2. The I2 in the north might be explained by later Albanian influx (there were some Albanian speaking regions in the northern Pelopenessos until recently).
