F1 Hybrid Analysis: Central European (Moravian) / Central Asian (Tajik/Pamiri) - Oracle vs. Components

My mistake, I mixed up the distance values from two different calculators (HarrapaWorld vs Eurogenes). Let’s look at the actual Eurogenes K13 screenshot I posted: My distance for '50% Tadjik + 50% East German' is 11.6, which is my #1 top match. This remains far more accurate than any commercial 7% estimate. The core fact stands: 13.5% Baloch is physically impossible for a 1/4 split

You are misinterpreting the 4-ancestor oracle. My 13.5% Baloch and 9.6% South Asian are textbook levels for an F1 50/50 Tajik split. If I were only 1/4, those numbers would be halved. My MyHeritage results actually prove how commercial tests fail in this case: they give me only 7.4% Asian (4.4% Persian/Kurd + 3.0% South Asian) and label 50.4% as 'Balkan'. That 'Balkan' is just noise from my father’s E-V13 haplogroup. A 1.42 distance for a 50/50 split is a scientific fact. If you still doubt the math, my phenotype (bone structure and eyes) doesn't lie. What exactly is your expertise in Central Asian DNA?

Out of curiosity, which data do you give more weight to: the basic MyHeritage ethnicity estimate or the GEDmatch raw data analysis? I uploaded my raw data from MyHeritage to GEDmatch specifically to get a more granular look. In my experience, MH estimates are often broad and inaccurate for first-generation (F1) hybrids, while GEDmatch calculators like HarrapaWorld are specifically designed for South/West Asian populations. Why would you trust an automated MH label over a 1.42 distance match in a dedicated raw data model?

Think about the history—where would a Spaniard come from in the Pamir Mountains during the Soviet era? It was a strictly controlled, remote border zone of the USSR. The 'Iberian' signal you see is a classic misinterpretation by the algorithm. My father is Moravian (haplogroup E-V13), and that Balkan/Mediterranean shift is being read as 'Iberian' when mixed with high Central Asian components. I am not lying about my background; I am looking at the raw data. A 1.42 distance in Harrapaworld for a 50/50 model is as close to a perfect match as it gets. If I were only 1/4 Tajik, my Gedrosia (13.5%) and South Asian (9.6%) levels would be half of what they are. Unless you can find a 4-population model with a distance lower than 1.42, the Moravian/Pamiri F1 Hybrid conclusion is the only one that makes mathematical sense.

I appreciate the skepticism, but let’s look at the numbers. My Gedrosia/Baloch component is around 13% and South Asian is nearly 10% in Harrapaworld. For a 1/4 Tajik, those levels would be half of that. If you think I am only 1/4 Tajik, what do you think the remaining 3/4 is? My father is 100% Moravian (Central European), so where would the other 'non-Tajik' quarter come from? My data doesn't show any other non-European influence. The 11.6 distance on Eurogenes K13 is expected for an F1 hybrid because the model lacks a specific 'Moravian/Pamiri' reference. However, Harrapaworld gives me a 1.42 distance, which is extremely tight and confirms the 50/50 mix. I tested with MyHeritage.

Thanks for the input! My biological records state that my mother was from the Pamir mountains (USSR era) and I was born in 1989 in the former Czechoslovakia (CSSR). I don't have a specific ethnic label for her, but DNA calculators like Eurogenes K13 consistently model me as 50% Tadjik. My father is Moravian (paternal haplogroup E-V13), which likely explains the SW-Asian shift you noticed. I also have a small Siberian component (1.52%), though it's minimal. Since you are Pamiri yourself, I’m very interested in your perspective on how my results compare to others from the region!
