Why did Persians mix so much with Mongols?

[Phenix]

Because the Mongol hordes raided the hell out of sedentary Iranians.

Where is your evidence of Persians mixing with Mongols?

In proper native Iranian people i have barely seen people with Mongoloid features.

Persian mixed with Mongolic you will find more among fringe groups like Turkic tribes,Central Asian tribes
and Uzbeks but among modern ethnic Persians or Farsi people its very rare i think

Hmm... I lived in a place with lot of afghan immigrants. I think most who look like that are hazaras and those are persian speakers.

This is a map showing maternal lineage origins of central asian populations. surprised iranians have a decent amount of east asian origin maternally.

Yes. It exists even among Iranians, but not arabs and very rarely kurds.

This map is wrong (or misleading) .

Iranians are supposed to have 10% Indian mtDNA just like in Y-DNA ( this has nothing to do with Indian women marrying Persian but it's prehistoric DNA ) it's just that ancient Persians were already South Asian admixture since PREHISTORIC TIMES. There was a veddoid race in ancient Persia. That's why in autosomal DNA they show always 9-15% autosomal prehistoric DNA related to modern Indian while they only have only a very few percent East Asian.

Also the Tajik and Turkmen DNA here seems a WAY higher than usual so they must not actual Tajik/Turkmen. They are are not higher than Uzbeks in every study I've seen. Also the Uyghurs here have only 3-5% west Eurasian they must be ethnic Yugur in China who are Uyghurs but are unmixed Uyghurs (or very minor mixed )

So the misleading mtDNA map haplogroup:

Iranians here were actually Azeris of North Iran
Tajik here were actually Kyrgyz Tajiks
Turkmen here actually Tekke Turkmen ( who have clearly more mongoloid admixture than average )
Uyghyur here are ethnic Yugur people (the original Uyghurs ) .


Here is their real DNA without any confusion




To prove that map wrong

Uyghurs

" A study on mitochondrial DNA (therefore the matrilineal genetic contribution) found the frequency of western Eurasian-specific haplogroup in Uyghurs to be 42.6 per cent, and East Asian haplogroup to be 57.4 per cent.[138] A further study shows that the western-Eurasian patrilineal Y-DNA haplogroup in Uyghurs is around 65% to 70%, and east-Asian Y-DNA haplogroup around 30% to 35%.[139] "

Kyrgyz ( and Kyrgyz Tajiks )

" West Eurasian mtDNA ranges from 27% to 42.6% in the Kyrgyz[37] with Haplogroup mtDNA H being the most predominant marker at 21.3% among the Kyrgyz.[37] "

The Tajik is most likely Kyrgyz because Kyrgyz Tajiks and western Kyrgyz have much higher western Eurasian mtDNA. Other Kyrgyz group also show much lower R1a for these same reasons " Other groups of Kyrgyz show considerably lower haplogroup R frequencies and almost lack haplogroup N.[35] (except for the Pamir[36]) "

Wrong

No you're wrong. Look at the average Hazara Y-DNA. The only difference is Mongoloid Y-DNA is most common but if you combine Caucasoid and South Asia which is the Y-DNA of Persian/Afghans (both who have preshistoric South Asian male ancestry ) than Mongoloid is not the most common. Ancient Central Asians also have prehistoric South Asian DNA although at minor level. They properly would look no different to how a blue hair/blonde hair with west Eurasian Y-chromosome look like example: Kalash, Hunza people... many of them look European but are actually south Asian admixed despite having haplogroup Y-DNA or mtDNA related with South Indians.

[Borealis]

Some of that Mongoloid ancestry came from earlier waves of Turkics and also Hun/Saka like people if I'm not mistaken. Anyway, most Tajiks are quite different from Persians genetically. I think a lot of "Iranian" speakers from Central Asia didn't even speak Persian.
