I have created a page dedicated the the genetics of ancient Gauls. I calculated the Dodecad K12b average percentages for 16 Gaulish samples and ran them against modern populations in Vahaduo to obtain the closest matches.
 
Congratulations Maciamo. Yes, very nice analysis for the ancient GauIs. I believe that Vahaduo Dodecad K12b can be a good calculator in most situations, especially if the miscegenation degree of the analyzed individual is not very high, which implies a greater correspondence of the individual percentages with the clusters of eachethnic group in populations spreadsheet. In my case, Portuguese and Iberian ancestry is evidenced with a the add of a small part of African ancestry, probably from slaves arrived in Brazil from Angola. The modern MTA calculator seems comes a little closer to the results of the EU K15, IMO.

Here is a Dodecad K12b PCA I had made of Bronze Age and Iron Age French samples compared to other ancient groups:

Nice work Maciamo and Jovialis: Thanks Duarte for sharing your results: My top 25 distances (gradiant 50) for modern using Dodecad K12 (Vahaduo): Dodecad K7 has the Ancient Roman samples by Cluster (i.e. C1, C2...C6..C7) which I think Jovialis worked on if I remember correctly. Is there similar clustering of the Ancient Roman samples from Antonio et al 2019 in Dodecad K12? I know using K7, I get strong clustering with the C6 cluster that Jovialis is showing in his PCA which I also get with Modern Italian samples in Dodecad K12 Modern and Ancient single. I would think those Dodecad K12 matches are in the C6 cluster using Dodecad K12 as well.

I have created a page dedicated the the genetics of ancient Gauls. I calculated the Dodecad K12b average percentages for 16 Gaulish samples and ran them against modern populations in Vahaduo to obtain the closest matches.

Interesting, Maciamo.
I notice in LN Switzerland, the Aesch25 (the only Y-R1b there and the late of the site) with 54,8% of 'north-euro', 19,8% 'gedrosia', a very reduced % of 'atlant-med', and 0% of 'NW-Africa' and Caucasus.
in other places, where I notice too some heterogeneity, we see the same link between 'north-euro' and 'gedrosia'; K12b is a special way (based on modern pops) to analyse admixture, and the opposition 'caucasus'-'gedrosia' has been criticised by someones, but I find all that very interesting, before to read it more serously. Thanks.
 
You speak of heterogeneity among Gauls, but the period of the highest heterogeneity is the BB's one, not surprising; after, it tends to homogenise progressively; all the way I wonder if the elite's exogamy doesn't explain the lasting of some heterogeneity; Celts were dominant tribes upon "loosers" before they underwent osmosis, and the DNA we have is I think rather the elite's one.
 
Nice topic
