G25-Based Similitud Map

[jstephan]

Hello,

For all the fans of Tolan's K36 similitud map, I created a G25-based version that contains All Davidski modern averages & French averages from the project Explore Your DNA, then I will integrate non-simulated Moriopoulos modern averages.

I am still integrating and geolocating the references so it's in process.

Similitud is calculated based on Euclidien distance.

It only works fine for people who are not mixed or slightly mixed, else it's going to focus on midpoints.

I am searching for non-simulated British and Irish sub regions, same for others countries.

Are the dots individuals, averages of individuals or both, depending on sample size?

I will send you a dataset for the cisalpine area.

I will send you a dataset for the cisalpine area. 

My closest matches on this map are in northern Piedmont, the two in Lombardy and the one in the Veneto.

I miss a lot of references for North Africa, I don't want to geolocate Nomadic Tribes or diaporas (eg Tunisian Jews) and I am not sure where to geolocate some of Davidski's references e.g example Moroccan_North, Berber_Algeria...

Really don't understand why I always get north Italy + Switzerland + north/central mainland Greece. Are these populations that similar?

They are not that similar, but they have one thing in common: They are a mix of a very Northern and a very Southern ancestral component. In case of Northern Italy it is mostly Celto-Germanic and diverse Mediterranean, in the case of mainland and Peleponnese Greeks it is Slavic and diverse Mediterranean. If the model focusses on North : South ratios, the outcome makes sense I guess.

I guess you have Eastern European/Slavic ancestry though? Because overall you rather tend towards the Eastern model, since your best hits seem to be in Albania/Northern Greece.

My ancestors were mostly from North Macedonia and were indeed Slavs who lived very close to border with Albania so I am not surprised about scoring similarity with Albania because on some models I'm even closer to them than Macedonians average, and the hometown where they were all from is geographically closer to Tirana than Skopje. Also I am not surprised for Bulgaria or Romania (last two due to general migrations from areas of Macedonia and Albania to those northeastern parts in last 400 years or even more). I don't know of any Eastern European ancestor outside of Balkan that is.

I am surprised for north Italy, Switzerland and south/central mainland Greece (ok, now that I think perhaps not so much with some areas of northern Greece due to geographic distance and historical circumstances).

Yes, similar ratios of ancient ancestry as Riverman mentioned

If you run 2 of yours most similar populations (Albania & Italia Romagna), they both get similar results on an Iron Age model, similar amount of Illyrian-Like and extra Anatolian + a Northern source (Celto-Germanic for Italians and Balto-Slavic for Albanians)

The dots are modern averages !
