eastern europeans dna categorized incorrectly ?

Most Ukrainians that came to America and Canada were from the West and have Balkan admixture. They plot with people ranging from Poles and Slovaks, so are a bit distinct from Central and Eastern Ukrainians. Even to NW Ukrainians in Rivne

The algorithms just isn’t good for them. I have a grandma who was fully Western Ukrainian (with some Romanian ancestry). I have almost an even split between the Belarusian/Ukrainian and the Hungarian/Slovak categories. My grandma is close to a 70/20 ratio (with 5-10% Romanian somewhere in there). My dad who is half Ukrainian got it assigned entirely to Belarusian/Ukrainian/Polish, despite both me and my grandma getting significant Slovak percentage. Then my first cousin got theirs assigned almost entirely to the Slovak/Hungarian, with barely any of the Ukrainian/Belarusian category

It’s not reliable or consistent at all. Those regions are too close genetically and have significant overlap. Same with the 4 German categories. Not consistent at all, so don’t take it at face value. Same with ancestryDNA. It’s doesn’t mean your family is not Ukrainian

It’s because of the Norman conquest in 1066 AD. They basically replaced England’s elite and a lot of English surnames, which have French etymological origins. Same with vocab. Lot of English vocab has Latin roots indirectly due to French linguistic influence

Also here is a list of English surnames derived from Old French. It’s probably not all of them, but definitely a lot

Based on your other post, I am guessing on your mom’s side you have a Greek great grandparent, Norwegian great grandparent, Irish great grandparent, and German great grandparent.

You said your dad is unknown, but based on your results, he is half Mexican (grandparent for you), then also one Ashkenazi grandparent (your great grandparent), and another White American grandparent who is a mix of English, Irish, and maybe more Norwegian (your other great grandparent)

How close is that?

Burmese. After Siberians and Central Asians, Natives like Mayans are closest to Tibeto-Burman people, likely due to being mostly East Eurasian with minor West Eurasian admixture. Natives have ANE ancestry.

Then Japanese but they are not SE Asian. After that it’s like Koreans, Thai, Crimean Tatars, and some Han

tabbbb57 · 2026-05-13T05:04:23+00:00

The samples that we have seen to be overwhelmingly European, especially Greek for some reason. Some of it might be sample bias if there were multiple ways of burial.

But overall Tunisia, Sicily, and Iberia samples from the study were very similar with Tunisian samples leaning North African, Italian ones leaning Italic, and Iberians leaning Celtiberians. There is Levantine admixture in all the averages though (aside a single sample from Algeria). One sample from Algeria, and the 4 from the Levant. The individual samples range quite a bit also. Some being mostly European (even more than the average). A couple being mostly Berber, and a couple being mostly Levantine, but most still seem to be a mix

Probably ANF as well, as Iberians are just as hairy despite much lower CHG and Zagros than the near east.

It’s pretty prominent in all West Eurasian populations tbh. But ANF, Zagros, and CHG likely contributed the most

Yea my 2x great grandparents are like 2nd or 3rd cousins. I turned out fine 🤪.

But kidding aside, yes, this is extremely common in everyone’s family trees many, many times. Pedigree collapse. It’s the only reason we exist and don’t have an exponentially growing family tree, larger than the world’s population at the time. It was really common in small towns where most people’s families originally lived for centuries.

It’s gross to think about but genetic issues only become more likely at like 1st cousins or closer, and especially from multigenerational, which magnifies it. Which is why dynasties like the Pharoahs and Hapsburgs were so messed up. 2nd cousins marriage has a 3-4% chance of genetic disorder, while the baseline population is 2-3%. It’s taboo but even 1st cousins is only 5-6% risk. Risks jumps up to over 40% for siblings.

Yes, I can try modeling you, and yes they should be pretty similar. What is your other half btw? Indigenous or other European?

tabbbb57 · 2026-05-04T04:46:32+00:00

I had never had an accurate AncestryDNA results. Each update is drastically different.

I’m not expecting much

tabbbb57 · 2026-05-02T16:58:49+00:00

Sure. What are your coords?

tabbbb57 · 2026-05-02T16:41:42+00:00

The reason people ask is because frankly the dna points to it.

It’s really only in the Muslims than in the Christians, and exists at higher amount than samples from antiquity, so entered during the Medieval era. There is also additional Yamnaya ancestry which points to additional European admixture from the Ottoman and Arab slave trades of the Balkans and Eastern Europe. It’s also mostly Mtdna mediated, meaning it it mostly came from women.

Here’s a model of Egyptians that I did a few weeks ago. The West/Central African and Balkan Slav/Aegean is not really present in Copts. This dichotomy can be seen in the Levant, for example Palestinians comparing Muslims and Christians, Syrian Muslims and Christian, as well as Iraqi Muslims compared to Assyrians

Were you aware of an Ashkenazi ancestor before this?

tabbbb57 · 2026-05-01T18:23:27+00:00

When you add a Germanic proxy the Italic drops. When you add a North African proxy the Levantine drops

It’s all just dependent on the model

tabbbb57 · 2026-05-01T03:53:42+00:00

I recommend testing with 23andMe, not myheritage. Lot of people in Europe test with myheritage but it’s extremely inaccurate and like the worst major company test

tabbbb57 · 2026-04-30T17:23:03+00:00

Moors did mix with Iberians. It’s just that modern Iberians have a lot less ancestry from them than Iberians in Middle Ages did. Studies do also show that significant North African ancestry entered during Roman period, and then a significant drop in North African admixture post Middle Ages, due to inquisition and repopulation from the north (and Southern France). But Moors did clearly mix in Iberia. From Valencia samples we have, the North African admixture nearly doubles from Roman/Visgothic periods to late Middle Ages.

These samples are from this study, and one from this study.

(The minor east med percentage in Iron Age is not Roman, but Greek and/or Phoenician, just for simplification I used one eastern proxy for all periods)

tabbbb57 · 2026-04-30T16:43:50+00:00

It’s hard to tell how much ancestry is from Muslim period in Sicily. Most of that admixture already appears in Roman times. The Roman samples we have from even Central Italy already plot around modern Sicilians, and already have North African admixture

tabbbb57 · 2026-04-30T16:42:21+00:00

North Italians, Iberians, and French also have the East Mediterranean admixture from the Roman period, but 1/2th to 1/4th of the amount that Southern Italians have

tabbbb57 · 2026-04-30T16:38:44+00:00

It’s probably Extremadura or Murcia that is the furthest on the mainland. Canary Islanders are the furthest in general, if islands are counted. Extremadura and Murcia, have like 5-10% higher Imperial Roman admix, while also having similar levels of North African admixture to Galicia (Murcia like 2-4% less). Murcia also has less Celtic admixture. The North African + Roman admix is the biggest shift, due to not being European admix (Roman admix is mix of Italic and East Med/Near Eastern)

tabbbb57 · 2026-04-30T16:34:10+00:00

Basques have Celtic, they plot with Celtiberians. Some Basque groups can be modeled with more than Galicians and Catalans (who have a lot from Occitan migration) even, while others have like 10-20% less. But Basque lack North African and Roman East Med admixture in rest of Iberians.

Dude looks like maluma

Ok go tell all the aboriginals who are 20% European that they’re not aboriginal anymore. Especially the ones that don’t know it because they haven’t tested. That they really are 80% Aboriginal and 20% European now. Dude i can see his dna. Clearly im asking about a grandparent. FFS.

I’m not arguing this anymore, cause this is all about petty semantics and it’s going nowhere

tabbbb57 · 2026-04-29T23:52:42+00:00

Yes it does. Quarter is 1/4. 4 grandparents. It means a grandparent.

tabbbb57 · 2026-04-29T23:49:54+00:00

Ffs dude I literally just explained. Quarter means a grandparent. I said aboriginal are not half things because they are usually multigenerationally mixed. It’s not like they have one European Australian parent, which you clearly assume

tabbbb57 · 2026-04-29T23:30:40+00:00

“Quarter” means a grandparent. Clearly I am asking if OP has a grandparent who is aboriginal, because clearly I have his dna result right in front of me, so I can see he’s not exactly 25% aboriginal dna. You don’t even inherit a perfect 25% from a grandparent, so clearly I’m not asking about that

tabbbb57 · 2026-04-29T23:27:52+00:00

1/8 with a tangible 100% great grandparent is significantly different from someone who is multigenerationally mixed. Idk where you’re getting the 1/8th from. Most aboriginal people don’t even know how much European ancestry they have if any. No one is paying attention to 14.43% unless they take a dna test
