neah
Haven't seen hundrends of Samples obviously,but the ones that i've seen(mine,members of the extended familyand few friends coming from the area) we're somewhere in the middle between the Islanders and the subgroups from the north.

Btw about the italian in MH,my own MH report show minor North african+Nigerian+Celtic admixture that never pops up in any other calculator so i can't it seriously.I think their algorithm is really f*cked up

Well maybe i inherited more from my maternal grandmother than my paternal grandfather since i have not any west asian.That can happen its not 50-50 i think

It's not exactly 50-50, for men it's 52% from mother and 48% from father for autosomals because in the 23rd pair you don't get autosomal X chr. from your father but the Y chr. which is not included in the autosomal breakdown that these PCA use.

For women it's exactly 50-50, 1 X chr. from each parent for 23 pairs.

Is this actual G25 or sim?if the first ,would you mind posting?

Did you get your own g25 coordinates from davidski or illustrative?or are the coords simulated?if they are not simulated can you share the coordinates?

Oh,no i didn't take my coords from them, they're sim.

can i somehow compare my ibd shared with other populations?And i have seen in a study that i can somehow predict the admixture times.Can i do that?
It was a study about cretans ''Supplementary Table 5. LD-based inference of admixture times and proportions for the Cretan population using ALDER. ALDER was run in 1-reference mode for different reference populations as sources of ancestry for the Cretans. We show reference populations with a clear signal of admixture (Z-score of exponential amplitude amp_exp and of Mixture lower bound ≥ 4). We also show in italics at the bottom of the table some populations of interest without a clear signal of admixture (notice implausibly wide date ranges). Present-day is taken as 1930 CE and generation length of 29 years and a 95% confidence interval (?1.96s.e.) is given.''
 
After Greece became independent in 1831, Phthiotis (that was included in the new Greek state) received Greek refugees from Thessaly (that remained ottoman for 5 more decades).

What's the source?

I am 50% from Phthiotis and this is a well known event in the area (people have family lores etc) but it is also well documented.

https://www.didaktorika.gr/eadd/handle/10442/23070

With that being said, I doubt the myheritage calculator is particularly sophisticated. I did input my 23andme results in there, however and it gave me interesting results. Besides 50% from Phthiotis I am also 50% from Messenia and the mix of a northern shifted maternal side (Phthiotis) with a southern shifted peloponessian paternal side (it scores Italian&Anatolian) puts me in the dead center of mainland Greek plots. Myheritage sees me as 83,9% Greek and south Italian, 12,3% Eastern European and 3,8% Ashkenazi. With the last one being an obvious misscall (23andme is great at picking Ashkenazi ancestry and I have none) from being a med with a bit of east euro input, it seems to me that myheritage sees me as 85% pre-migration era Greek/15% early Slav. The majority of the latter almost certainly comes from my maternal side (extremely blonde/grey eyed great grandma). This agrees with both Stamatoyiannopoulos’ figures and Razib Khan’s who sees modern greek being on average about 83% bronze-iron age Greek like and 17% polish like.

I scored no Balkan which isn’t a surprise since 23andme found zero areas in Albania or Bulgaria for me (I only have a handful of supposed Albanian cousins but they appear to be partially Greek). In fact I didn’t score any Eastern/western Macedonia or any Thrace at all either. Whatever Slavic input that is it appears pretty old.

You're lucky that your results make some sense

MH somehow found italian,Celtic, Ashkenazi,North African, Finland & Nigerian admixture(when all of my greatparents are from Nafpaktos subregion)
Fun fact none of them pops up in any other calculator.
 
Yeah I was surprised they made sense. Because whatever their calculator is trying to see or interpret usually makes zero sense. For a company founded by Israelis their calculator is surprisingly bad at estimating Ashkenazi origins. And Finnish ancestry for a Greek is kinda ridiculous, it is as if it is trying to compensate for something.
 
i dont think that this influenced my ancestry to put me so northern.
I have a grandfather who lived in Macedonia,who had pontic surname,
and my test dna proved he had heavily mixed with local macedonians.
His pontic side is like 6,25% (1/16 ancestors).The other 93,75% is local macedonian.
that macedonian ancestry could influence me by 20-25%.We should also take into
consideration my Sarakatsani Ancestry.

The whole pack doesn't make any sense:
Finnish=Zero Siberian/Central asian/uralic found in all calculators
Ashkenazi=Zero Natufian/Levant
Nigerian+North African=Zero Taforalt or subsaharan
Celtic=Zero WHG
As for the Italian part i noticed in MTA's deep dive and in other calculators that the only italian samples close to me are some heavily East med Roman era samples.


All the calculators give combinations of Anatolia/Aegean_N(60-65%)+CHG/Iran(10-15%)+EHG/BHG(22-27%) and nothing else.
I was expecting some Balkans+Eastern Europe in MH and got almost anything else
