IBS / IBS SC Asian distances

I still dont see Why being seperated and Not being mixed for thousands of years Would make Anyone different baser on dna tools. Havent seen that before.

But i now Think the results for the balochs make some sense, Apart for the lezgins thrown in

[Avicenna]

Very nice bro ! Will you be doing one for afghans too?

[Lucas]

If possible, I think it would be helpful if the ‘iranian’ samples would be a bit more specific. I highly doubt some of them are ethnic Persians or native Iranics if they are farther away to Pashtuns than Finns and Uyghurs...

In fact few academic Iranians are in fact local Arabs (Khuzestan or coastal). I mean those academic reference called "Iranian", not later regional like Fars, Mazandarni, Bandari.

Tbh, Im Not sure If We should expect them to be very much like the arabs(likely influenced though)

I already have gulf South iranian alike samples with very arabic names(and seen some of them even wearing arabic clothing clothing). I even has a sample of some guy from the gulf considering himself arab, Although his results screamed South iranian(even has a lot of South east eurasian admixture, compared to other South iranians).

Unless We see results of these samples, i wouldnt expect them to be very arabic alike

Well the proof is in the results. When we did the Kurd and Pashtun samples Baloch/Brahui were not in the top of the list but when we reversed it and did a table for Brahui all of a sudden Kurds and Pashtuns are in the top. Read that technical paper I linked it's helpful. Also google "genetic bottleneck" or "genetic drift".

I have a beautiful example that will make it clear to you.

Going by the previous example I gave suppose for simplification Sulaimaniya in Kurdistan only has 10 kurds and these are there genotypes for a certain SNP. You'll notice the allele frequency for the "A" allele at rs853697 is 70% for these Kurds

SNP	Kurd1	Kurd2	Kurd3	Kurd4	Kurd5	Kurd6	Kurd7	Kurd8	Kurd9	Kurd10	Allele Frequency “A” allele
rs853697	A	A	C	A	C	A	A	A	C	A	7/10 or 70%

Now supposing Kurd3, Kurd4, Kurd5 decide to go to an uninhabited island

SNP	Kurd3	Kurd4	Kurd5	Allele Frequency “A” allele
rs853697	C	A	C	1/3 or 30%

You'll notice that the Kurds on the island have a totally different allele frequency than the Kurds that remained behind. Now you can do the table for all the other positions in the genome.

After 2000 years admixture calculator will show totally different profile for them even though they never mixed with anyone.

Sure we can't leave out the Tajiks Keep in mind though I only have a couple of Tajiks in this dataset

Sweet man . Be sure to include afghan pashtuns too

I havent seen any admixture calc do that, Not even for kalashis or nuristanis.

But Thanks for the explanation

how else do you think we can tell apart Yamnaya, WHG, etc. ancestry?
it's because they were originally small isolated tribes with a specific genetic signature.

Sure you have remember the good old "Baloch" or "Kalash" components. They create their own components in Admixture not because they are so different from their neighbors or W. Asians but because of their drift.

That's why on calculators with Baloch component Baloch distances are so odd (far)
