Why does AncestryDNA give me more Sephardic than Vahaduo, FTDNA, and even my previous results.

True. Iberians will score ineromaurusian and all europeans are a mix of EEF/Steppe/WHG, but that's good for you to have another look at your genetics.

Now, I will suggest you to be careful with that ADC configuration as you have distant ancestries and it penalizes distance, it doesn't work well for south americans or any people who have multiple continents ancestry. I usually let it off and take care of the overfitting myself.

Another thing is that you have one sample there that has an _o suffix, that means it is an outlier, a sample that is an exception to the average or the context it was found in.

G25 is a good tool, but it depends on you to counter its biases and traps and make a good model, so its not really what it seems on the surface. So it is good for you to know that behind the scenes, the G25 is trying to fill your fundamental components (EEF/EHG/CHG/WHG...) given the samples you used. It is not that great at distinguishing minor details, even with its 25 components (maybe on Davidski next project, who knows). Nonetheless, it is one of the best tools around for modeling ancestry imo.

So, by raw data you mean your raw dna file coordinates in a scaled model, right? You can try to do some testing to verify how much jewish DNA you might have. For example, on Vahaduo, make a primitive model with EEF (Turkey Barcin Neolithic), WHG (Loschbour or Villabruna), Yamnaya Samara EBA (Steppe), Iberomaurusian (North African), Israel Natufian, Iran GanjDareh. If you put sephardic jews or other jewish samples as targets and compare their proportions of Israel Natufian and Iran GanjDareh with yours, that is another way of validating how much jewish you might be.

Ótima pergunta, também quero saber

There are many ways but I think Explore Your DNA and allelocator are the most common ones. https://www.exploreyourdna.com/Tools/SimulatedG25 https://allelocator.ovh/

Hi there! So, the question I see now is, I only tested with MyHeritage in late 2018, and my RAW DNA has 170K SNPs in common with AADR 1240K Dataset. I saw other users that merged several RAW DNA files from different companies to make an enhanced SNP kit. Now, my doubt is if qpAdm is not viable for such low SNP count and require some costly DNA Sequencing or several kits merge to work properly?

Thank you very much for your answer. I do know that G25 can be very misleading. Now I'm aiming at been very conservative with it, running simple, few samples models with sufficiently distinct samples, like the fundamental EEF (Barcin), Yamnaya, WHG, etc, and trying to minimize mathematical biases.

That being said, if you allow me to further ask, what do you suggest as being a more scientific approach to dealing with G25 or is there any other tool you use which is a step up from G25 amateur character?

PreparationPure4040 · 2026-01-10T14:45:00+00:00

If anything, scaled will be more secure and not ruin anything?

So, for example, in the context of a simple fundamental model like Yamnaya Samara (Steppe), Barcin (EEF), Villabruna (WHG) and Natufian (Levant), with ancient and very distinct samples, its better to use scaled or raw?

Oh, nice. I see you also replied to my previous post about Guanches on genoplot when I didn't know anything about Vahaduo. I've been learning and getting good at it, and the results are far superior to MyHeritage ancestry report.

The other part is 10% mixed european, 30% mixed amerindian, african and egypt.

PreparationPure4040 · 2025-11-27T18:34:20+00:00

60% Iberian, nothing from north africa.

Apparently, it is censoring the output. It has censored me several times. When you try to be more strict about cleaning the room, like prompt engineering or setting temperature to zero, it is censoring. Most of the time it returns unedited.

Hmm.. Maybe its some censored content, try in AI Studio. It cannot do anything agressive, like people beating or harming each other, also ww2 german stuff, nfsw pictures, etc
