Slavic G25 (ancient) calculator

[Lucas]

Usual discrepancy between my parents results and mine as in every Gedmatch or G25 calc I think FTDNA tested them using different chip, although it was not officially stated. SNP number is the same anyway.


To have higher Baltic and Greco-Roman in the same time than both of them is not very probable...

This calculator could use a reboot. I am thinking maybe I should not inlude samples as old as bronze age, only medieval and iron age. Could improve accuracy, maybe.
And add few more samples, remove less clean ones ?

Scythian Moldova, I have it as one of Paleo-Balkan samples, which exact time frame is that?

[Jana]

Need a piece of advice: could some of IA French samples be added as Celtic proxy, if they are any good, and if yes, which?
Also thinking to include some Hungarian Scythian for Paleo-Balkan (very southern shifted results) plus Empiures as another Greek sample.

Opinions?

I'd remove BA Balts and BA ''Croatians'', probably it is true they have no yet specific Baltic or Illyrian drift so they skew some results. Also Lech because it's also BA. And I am thinking to remove early Czech Slav, but didn't decide yet because it's local admixture is very small.

Since I have only one Germanic sample, I was thinking to add Iron Age Danish sample too, if it's clean (it should be, right?)
so many questions.... ))

[Lucas]

Since I have only one Germanic sample,

Which sample it is?

You can use Poprad or those Szolad samples which are highly Germanic, as good proxy of early medieval Germanics in Central Europe.

Which sample it is?

Germany Medieval

I just wonder Lukasz, do you think you really have significant Baltic admix or is this just shared Balto-Slavic ancestry in BA before groups separated? I did thest those samples I chosed and they are all firmly closest to modern day Balts, but I am suspicious you score less Slavic than I do.

That is why I start to doubt how much reliable these samples are.

looking forward to the reboot! yes i agree remove the samples wich are a not so clean. Because with my results i dont get my 1/4 Germanic because there was already some Germanic in the Balkan sample and when i removed it i got my 1/4 Germanic.

There is no Germanic in Balkan samples, but there is western European drift in it (bell beaker and even "celtic" like-not actual celtic at all though, just genetic overlap).

These samples are not mixed if that is what you mean, entire Croatia was homogemously North Italian like in bronze age, both in Dalmatia and Slavonia and very similar to early Italics/Latins, Etruscans and Republican Romans.

But, I doubt such genetic profile remained in Balkans for long because modern Balkanites (even most Croats) usually can't be modeled with it so well. Maybe it became already more southeastern like in iron age. IA Croatian sample is mislabeled as far as I know and actually just late BA one (someone please correct me if wrong, it's important for bigger picture)

I can be modeled with it, but well, I think that is because I am part west European so it eats my western admixture similary like yours.

No point in this calc for NW Euros, especially not for Irish since their mix requires NW Euro Beaker samples, which for Slavs/eastern euros aren't relevant.
