Are these admixture maps accurate?

The gradient maps are the admixture maps, the solid colour maps are the areas he's considering apart of the supposed races.

West Eurasian

East Eurasian

Sub-Saharan African

West Eurasian, East Eurasian and Sub-Saharan African admixture maps all merged into one.

The Sub-Saharan one isn't accurate. Lol at part of Spain and Portugal having as much SSA as some North Africans.

Compared to all other maps online, this is fairly well done. This dude puts in a lot of effort. I appreciate his work. Saw some of his youtube videos before.

There are some flaws though. Ill just focus on the subcontinent.

- gujarat is just as western shifted as nw india and pak on this. Thats very inaccurate. Infact groups like baniays and patels are comparable to south indian mid and brahmin castes. Only exceptions are lohanas, kutch muslims which i guess he highlighted through coastal Gujarat, though they dont stretch as east/south as shown.

- northern pak and kashmir are the most west eurasian in south/south central asia according to the map. That doesnt make sense since they have more Asi and some mongoloid compared to pashtuns and balochis.

Not at all. Southern Portugal isn't the same level of SSA as Northern Morocco.

No they are not accurate at all especially for North africa

Actually this "SSA" in northern morocco is not ssa but related to ANA who spread into west africa and influenced tribes like the yoruba so it's shared alleles but not a real ssa component :

Moreover, our model predicts that West Africans (represented by Yoruba) had 12.5±1.1% ancestry from a Taforalt-related group rather than Taforalt having ancestry from an unknown Sub-Saharan African source11; this may have mediated the limited Neanderthal admixture present in West Africans23. An advantage of our model is that it allows for a local North African component in the ancestry of Taforalt, rather than deriving them exclusively from Levantine and Sub-Saharan sources.

It's pretty good i think apart from:
Finland and Hungary = east eurasian... no.
and the southern spain/portugal thing goin on.

So you think there's no black blood in North Africa? I think since that population you refer to was not Eurasian and was most likely very dark-skinned we can safely call them Africans.

Good maps overall, only problem is he has an outdated notion of West and East Eurasian, he's counting all of ANE as West Eurasian when it's literally from Siberia and a mixed component, not outlier one. Should've called them Caucasoid and Mongoloid.

Also it looks like he looked at an African admixture map that included an East African component(which is already a mix of West Eurasian and SSA) for Europe and the Middle-East but then a pure SSA component admixture map for Africa, which is problematic.
