Please help me interprate my gedmatch results

[xripkan]

Hello, so I upload my results on gedmatch and I have used mostly the eurogenes calculators. I would like some help to unerstand better the results and especially the combination of the populations. For example I found strange the fact that in many calculators I have some jewish results despite I do not know anything about a jewish ancestor. How can I interpret that?

Jews (especially Ashkenazi Jews) are genetically similar to Greeks and South Italians due to having similar components. This doesn't mean that you have ancestry from them.

I assume you are from the Peleponnese?

[xripkan]

Yes I am 3/4 from Peloponnese and 1/4 from Thessaly.

Jews (especially Ashkenazi Jews) are genetically similar to Greeks and South Italians due to having similar components. This doesn't mean that you have ancestry from them.

Actually I have recently received my DNA results from 23andme and I had 2% percent arabian and North African DNA . It was all at X chromosome and it remained in every confidence level. According to my gedmatch I have big distance from every other population from this region. That is why I think I may have some Jewish ancestry but I don't know if gedmatch works in that way. Am I right?

[Rgvgjhvv]

Yes I am 3/4 from Peloponnese and 1/4 from Thessaly.

Ya your results are very typical for that region. Non-Greek results are just telling you which populations are genetically close to your results, and not a sign of any ancestry from those regions.

[Sikeliot]

Jews (especially Ashkenazi Jews) are genetically similar to Greeks and South Italians due to having similar components. This doesn't mean that you have ancestry from them.

Some Greeks are too Slavic to be similar to Ashkenazim and southern Italians.

This particular result seems somewhat shifted toward Spain though (high Atlantic).

Could you post dodecad k12b?

The GEDmatch version of Oracle may give slightly different results from Dienekes version. The GEDmatch version uses FST weighting in its calculations.
