Question about R1a

[Jana]

My step father (who is deceased) was predicted to belong to R1a-Z2125 (a subclade of Eurasian Z93) by usually highly reliable yseq cladefinder tool. However I heard yseq has problem with this particular snp and gives lot of false reads for Z2125. Afaik, Gixajo was also predicted to be Z93>Z2125 and later (with a proper test) he turned out to be subclade of Z280, not Z93 at all.

As for Morely predictor, it just shows my step father to be broadly R1a-M417 and nothing specific.

There is ethnic Croat sharing the same surname as my step father who belongs to R1a>Z280>CTS1211>Y35>CTS3402, which is a usual Slavic subclade and most common type of R1a among Croats.
Their surname is specific for one region only and less common elsewhere, and my step father native region main haplogroup is R1a Z280, while Z93, especially such exotic "Pashtun-Tajik" branches such as Z2125 are unheard of.

In my opinion, my stepdad was likely under Z280 like other Coat sharing his surname and probably not Z93.

What do you think?

[Leto]

Your stepfather was the last of the Aryans...

Yeah, Z280 is of course much more likely in Croatia or anywhere in Europe for that matter.

Their surname is specific for one region only and less common elsewhere, and my step father native region is pred. R1a Z280, while Z93, especially such exotic "Pashtun-Tajik" branches such as Z2125 are unheard of.

What do you think?

afaik, Z93 in Europe is found in trace amounts except in some VUR groups, so statistically he's probably not Z93.

I read from Kyp other people too (on Anthrogenica maybe?) noticed yseq problem with false reads for Z2125. I wonder why is that.

What do you think?

It seems that is quite usual that error. (Z2125 instread of other M417 subclades) using some commercial test autosomal raw data in cladefinder.

Someone warned me when they predicted me as Z2125, so it must be something common.

Then I tried a Yseq R1a super panel to know for sure my Ydna, I think you advised me to test with Yseq.

I really liked their way of working. Very close people and always ready to inform you of any detail.

Apparently R1a-Z2125 is of Iranic origin. Predictor might have been wrong.

I just asked Thomas Krahn, the owner of YSEQ, that is also into the cladefinder. I'm curious what he will say. Maybe there is some imputation and guesswork involved.

[Arūnas]

thanks God it's a subclade of Eurasian Z93, on wikipedia I read that Roma people can have Z-93 in Croatia and Hungary

What raw data did you have?

Same thing happened with the MyHeritage raw data of my father when I ran it on yseq cladefinder. He got a false Z2125.
When I made him take the 23andMe test he turned out to be CTS3402.
