Yes 3.5% , my siblings all got different traces too, even at 90% confidence Iranian, peninsular Arab, Pakistani/North Indian, Malayali and broadly European, barely anything changed for my grandmother.
@NidarNidar @giire12 Do feel this update is better? I've noticed a strong pattern the only 100% scoring Somalis left are from the deep interior
Interesting, I would never have thought you can go from 100% back to 96.5%, you all inherited different traces, maybe there is more then one distant parental line who is heavily mixed which could be the reason for traces not disappearing at 90% confidence level. 23andMe promised parental inheritance features on the chromosome painting, did you see any the promised features?
I am assuming its better and more accurate, they said
"Enhanced Accuracy: The accuracy of these new ancestry results are greatly improved by using our recently published, state-of-the-art DNA phasing method. You could think of phasing as sorting which DNA you inherited from each parent. Reducing errors in phasing means a more accurate estimate of your ancestry percentages and better DNA Painting "
"Improved algorithm, expanded populations, better results".
"We start by dividing your DNA into short windows, and then we phase it. Phasing is how we determine which parts of your DNA came from each parent. Then, we compare each window to dozens of reference populations, generating likelihood scores that help us assign ancestry and summarize your results.
With this update we've improved our phasing method to reduce errors by 98 percent, boosting the precision of your ancestry assignments. We’ve also upgraded how we assign ancestry across your genome, using the most likely match at each segment instead of requiring a strict likelihood threshold. This means no more vague “broadly” categories, and more specific, detailed results you can trust."
A Major Update to Ancestry Composition
Over the last few months, we’ve been hard at work finalizing a major update to your favorite report: Ancestry Composition.

Interesting. I went from 100 to 98.2%

Its good to know that NEA is Somali, I like that even at 90% confidence level your unassigned is only 0.7% and 80% its 0.4%. Could the Nigerian be from Oromo side who are known to assimilate other ethinic groups?
90% confidence level i get 11.2% unassigned.
Also I found a video of an Ethiopian Oromo with 0.5% Broadly West African on the pervious version.

I hope more people share, cause it will paint a very nice picture.

My update. It's perfect as it aligns with my Arab and Ethiopian ancestry analysis I did years ago. But it added South Asian ancestry I don't have.
The 1.6% Egyptian is gone (that ancestry used to be Anatolian, general Near Eastern associated but was definitely just something from Yemen).
As to reconcile the South Asian, in the rare cases I modelled using unscaled coordinates, people somewhere in Tibet come up.
I think this might be mostly Basal expression of very ancient drift but perhaps some of that might vicariously channel through the Central & South Asian, since I suspect there was a calibration of scales tradeoffs on the margins.
Overall it's good but it would be nice to remove that ancestry, given that I have explored my ancestry and know I don't have it. It could also mean this South Asian is a same thing as previous channelings, just registering the Anatolian Neolithic aspect, once again.
What I think is more likely, when I use overfit datasets on scaled coordinates, the result will give me Papuan. This is clearly basal stuff and I think this might align with what appears in the 0.3% alocated to Central & South Asian.
Overall, The Somali, Ethiopian and Arab is perfect.

I'm dropping this here:
When I look at north Africans, Punic lineages appear more than what is mentioned. I think the Levantine ancestry is Phoenecian. Take the Libyan Arabs, for example. They have a mixture of Toubou, Egyptian, and Arab, and around half Berber.
These Carthiginians spread towards other places, lived and mixed among them since the early days, and I think, after the fall of that civilzation.

There’s multiple layers of Levantine ancestry depending on the origin of the individual especially if they are of urban origin. In general coastal tribal Berbers do have significant East Med ancestry from not just the Carthiginian (whose mercenaries many times were massively sourced from the East Med). Most of the Northern Berbers actually came much later to the Western Maghreb (Western Algeria/Northern Morocco Med coast)
My wife who is half Northern Berber/Arabized Berbers also has a substantial Levantine admix. You can see this East Med admix from Northern Moroccan Berbers all the way to Tunisian coastal Berbers. Libyans source majority of their Berber ancestry obviously from coastal Berbers that were absorbed by the Hilali/Sulaymi Bedouins as most Libyans lived along the coasts.
