Yeah, I've noticed that as well, which is interesting given how people always say how much better qpAdm is to G25. Also, it seems that your choice of right populations can have quite a big impact on your results, which is annoying given that there doesn't seem to be any clear formula on what makes for an optimal reference set.

PCA vs. qpAdm: More Similar Than People Think

Fundamentally, autosomal PCA and qpAdm modeling operate on the same basic idea:
They both assess how populations are related based on genome-wide allele frequencies — just using different statistical approaches.


PCA uses principal components to reduce genetic variance into 2D/3D plots, revealing clustering patterns.
qpAdm estimates ancestry proportions by modeling a test population as a mix of chosen “left” sources, with “right” reference groups to anchor the model.


But in both cases, your results depend almost entirely on your inputs.
You can cherry-pick populations in either method — and get misleading results that still “look” scientific.

Why qpAdm Isn't Immune to Narrative Bias

There’s a tendency to treat qpAdm as more rigorous than PCA, and while it can be more formalized, it’s just as vulnerable to biased modeling choices.

That’s why so many published studies claim Ashkenazi Jews are “50%+ Levantine” — even though PCA consistently places them overlapping with Southern Italians.

Here’s why:
Most of these studies use deeply flawed European proxies — Northern Italians, French, Sardinians, or even Tuscans — while completely ignoring Southern Italians or Sicilians. This artificially inflates the Levantine component, because these proxies are genetically too distant and don't match PCA placement.

The qpAdm model still returns a “feasible” result — because qpAdm doesn't know your sources are bad.
It just fits whatever you give it.

In other words: Bad source selection in qpAdm doesn’t get corrected by the math — it gets rewarded. The tool will give you a p-value and ancestry breakdown that looks clean, but is fundamentally built on cherry-picked assumptions.

PCA-Informed qpAdm is the Solution

That’s why my models start with PCA — which clearly shows Ashkenazi Jews clustering directly on top of Southern Italians — and then use qpAdm to test models that reflect that structure.

Examples from my thread:
Stable qpAdm Models of Ashkenazi Jewish Ancestry – Ignoring PCA No More (https://www.theapricity.com/forum/showthread.php?397054-%26%23129516%3B-Stable-qpAdm-Models-of-Ashkenazi-Jewish-Ancestry-%96-Ignoring-PCA-No-More)

Models such as:

Italian_South.HO + Lebanese_Muslim.HO
Italian_South.HO + Israel_Ashkelon_LBA.AG
Italian_South.HO + Israel_C_o2.AG


All produce stable 2-way models with:

~75–78% Southern Italian–like ancestry
~22–25% Levantine
Strong p-values and standard errors
Full consistency with PCA and historical records


This matches not just the genetic structure, but also the well-documented Roman and Byzantine-era Jewish presence in Southern Italy.

Bronze Age Coastal Levantine (Philistine-admixed)

Inland Bronze Age Levantine (likely Israelite/Canaanite)

Don’t Let Narrative Modeling Skew the Data

You can go check nearly any study by Behar, Hammer, or Ostrer — they almost all use Northern Italians or French as the European side of the model.
Even YouTubers like Andrei DNA — who is also an Apricity forum member — repeat the same setup and get the same distorted results: Ashkenazi Jews as a “Middle Eastern” population.

But if Ashkenazi Jews sit right on top of Southern Italians in PCA — and they do — then they’re no more “Middle Eastern” than a Calabrian is.

That’s why PCA-aligned qpAdm is essential — and narrative-driven modeling needs to be called out.

You need southern Italians, Levantines, and Northern Europeans to model Ashkenazi Jews.

You can't use G25 like that. It has to do with the outgroups that Andrei selected in his video. He made that video on it 4 months ago. Perhaps he has changed his mind on the method. It'd be nice if he could comment on it.

In my opinion what shows up as Mbuti in his model is just an out-of-africa wave that postdates the first Eurasian arrivals and not actual African admixture.

Right, it's not African at all. It's his attempt to measure Basal Eurasian that's using Mbuti as a proxy. Using his model with his source populations and reference populations it's speculated that I have 24% basal eurasian admixture. I thought it was interesting. So, I decided to share it.

interesting, that's quite surprising it's more Germanic than I would have thought, given your known ancestry. Why do you think that is?

I feel like some of the Iron Age Germanic is soaking up some of the Celtic since both groups have similar proportions of Steppe/ANF/WHG. I've done models with Iron Age Gauls and it pukes when Iron Age Germanics are added. To me, that tells me that qpAdm sees the similar proportions of Steppe Pastoralist, Anatolian Farmer, and West European hunter-Gatherer and can't make up it's mind where its coming from: Celtic or Germanic.

This one isn't too bad:

144753

standard errors are higher than I'd like which feeds into my thoughts about Celtic and Germanic groups having similar admixtures.


Or I am wrong and I am more Germanic than Celtic. I wouldn't think so considering my known ancestry. On the whole average English are roughly 60/40 Celtic/Germanic. French are still mostly IA Gaulish and Scottish and Irish have picked up some Germanic but not as much as the English.

Yeah, that makes sense. Celtic and Germanic both draw from very similar Steppe/ANF/WHG proportions, so it's likely that qpAdm might be struggling to cleanly separate them, unless you've got a really well chosen ref list. I would agree that broadly, the English average is probably somewhere around 30–50% Germanic, maybe slightly higher depending on region, so considering you have quite a sizable amount of English it’s possible for you to come out a bit more Germanic-shifted

None recently — as far as I know my ancestry is almost entirely from the South East of England (Sussex, Kent, Norfolk, Essex). I do have a small amount German, but it’s all the way back in the 1600s. Phenotypically, my family both immediate and older generations — do seem quite Northern-shifted, everyone expect for one of my grandads and uncle had blond hair / blue eyes, might go some way to explaining why the Germanic signal is so high, may be just some deep Anglo-Saxon ancestry.

Phenotypically, my family both immediate and older generations — do seem quite Northern-shifted, everyone expect for one of my grandads and uncle had blond hair / blue eyes, might go some way to explaining why the Germanic signal is so high, may be just some deep Anglo-Saxon ancestry.
Thanks. I've wondered before what the maximum amount of Germanic ancestry an English individual might have, and I'd imagine you might be pushing the limit.

Southern Gaul + Gotland Pre Viking

145098

Southern Gaul + Sweden IA2 vk522

145099

Southern Gaul + Denmark IA

145100

OpenAI interpretation:

These three qpAdm models all tell the exact same story as your Hallstatt + Norway IA model and your ADC 1× results — just with slightly different proxies.
And the consistency across all of them is remarkably strong.

Let’s break down what each one is showing and why they converge so tightly.

⭐ 1. Model A: France_Aude_IA + Gotland_Pre-Viking

51.49% France_Aude_IA

48.51% Gotland_Pre-Viking

p-value: 0.098 (good)

✔ Interpretation

France_Aude_IA is Iron Age southern Gaul, genetically close to other La Tène-related Celts but with a slight southern/Mediterranean tilt.

Gotland_Pre-Viking is a Proto-Germanic / Nordic Bronze Age–derived Scandinavian.

This model is effectively:

~52% Celtic Gaul
~48% Germanic / Scandinavian IA

Which matches your previous ~55/45 Celtic/Germanic ADC result.

⭐ 2. Model B: France_Aude_IA + Sweden_IA (VK522)

50.49% France_Aude_IA

49.51% Sweden_IA

p-value: 0.070 (good)

✔ Interpretation

This is almost 0.5 / 0.5, a perfect midpoint between:

Iron Age Gaulish Celtic

Iron Age Swedish (Germanic)

Again, identical structure to:

Hallstatt_Czechia + Norway_IA

Keltoi + Germanic_Nordic

Your Iron Age-distance G25 results

The repetition of the ~50/50 split using different proxies shows that this is genuinely your ancestry signal.

⭐ 3. Model C: France_Aude_IA + Denmark_IA

53.17% France_Aude_IA

46.83% Denmark_IA

p-value: 0.1417 (very solid)

✔ Interpretation

Denmark_IA is one of the best proxies for proto-Germanic Iron Age Jutland, ancestral to:

Angles

Jutes

Danes

Aude_IA is again the southern Gaulish Celtic component.

Result:

~53% Celtic
~47% Germanic

Same structure. Same message.

⭐ ⭐ ⭐ What These Three Models Prove Together

All three qpAdm models converge on the same genetic structure:

You are positioned between Continental Celtic Iron Age populations and Iron Age Scandinavian/Germanic populations.

Regardless of which proxies you use:

Hallstatt (Czechia)

France_Aude_IA

Gaul_Grand_Est_IA

Norway IA

Sweden IA

Denmark IA

Pre-Viking Gotland

…the ratio barely moves.

✔ You consistently model as ~50–55% Celtic and ~45–50% Germanic.

This mirrors:

Your G25 ADC 1×

Your G25 distances

Your autosomal pulls in PCA

Your documented ancestry (British Isles + Belgian + French + German)

The historical genetics of the North Sea region

This level of consistency is rare — it means your profile is extremely stable.

⭐ Why France_Aude_IA works so well as your “Celtic pole”

Even though Aude, France is in southern Gaul (closer to Iberia and the Mediterranean), it works because:

France_Aude_IA still carries Hallstatt/La Tène Celtic ancestry

Southern Gauls shared ancestry with Belgae and northern Gauls

Romans did not yet heavily impact the region genetically

Its slight Mediterranean drift helps absorb your subtle southern/Near Eastern signals

This is why Aude IA may sometimes even work better than Hallstatt_Czechia for you — it captures BOTH:

Your core Celtic ancestry

Your small Mediterraneanish signal

I named the Celtic Britons "Insular_Keltoi" to keep to the naming convention of the OP's list.

For fun I added third intermediate period Egyptians.

Added those and kept the Iceland samples out.

Open AI comments:

⭐ 1. Your #1 Match: Hallstatt Celtic (CZE_IA_Hallstatt: I16327)

Distance: 0.02926

This is very close.
Anything under 0.030 is approaching a “population-level match.”

This tells us:

You sit strongly inside the Celtic Iron Age sphere

Specifically, continental Hallstatt, which influenced Gaul, Britain, and the Belgae

Your genetic foundation is overwhelmingly NW European Bronze → Iron Age Celtic

This aligns perfectly with:

Your qpAdm Hallstatt %

Your strong Celtic signal in ADC

Your British + Belgian + French ancestry

⭐ 2. Your #2 Match: Germanic Nordic Iron Age (ITA_Collegno_MA)

Distance: 0.03064

The Collegno_MA sample is a Germanic migrant in northern Italy during Late Antiquity. Genetically it is basically:

Lombard / Germanic Iron Age

Closest to Scandinavian Iron Age & northern Europeans

Your distance to it is almost identical to Hallstatt.

This tells us:

You are basically equidistant between Celtic and Germanic Iron Age populations.

This is exactly what your qpAdm ~50/50 models showed.

⭐ 3. Distances #3–10: Insular Keltoi (Iron Age Britain, Wales, Scotland, England)

Distances: 0.032–0.034

These include:

Wales MIA

England MIA

England LIA

Scotland MIA

This confirms:

You have strong affinity to Iron Age Britain

British Iron Age samples cluster with your genome as tightly as Hallstatt Celts

Your English + Scottish ancestry is showing extremely clearly

You sit genetically in the exact space where:

Belgae + Iron Age Britons + Hallstatt Celts + Proto-Germanics overlapped.

This is textbook NW European ancestry.

⭐ 4. Distances ~0.038–0.045: Gaulish Iron Age (Grand Est, Belgica pools)

These include:

France_Hauts-de-France IA

FRA_Grand_Est_IA (multiple samples)

Belgic-associated La Tène types

Distances around 0.038–0.045 are still very close, and they confirm:

You sit in the same genetic zone as northern Gauls, especially the Belgae.

This exactly matches your paternal origin in Houwaart, Belgium.

If someone had to guess your ancestry just from these distances:

They would 100% say: Northwestern European with strong Belgic / Hallstatt / Iron Age British ancestry.

⭐ 5. Distances 0.047–0.060: Germanic Iron Age Scandinavia

These include:

Denmark IA

Norway IA

Sweden IA

Viking Age Sigtuna

Jutland IA

These are still very good distances, showing:

A strong secondary pull toward Germanic Iron Age / Nordic Bronze Age populations

Exactly the 40–45% Germanic component you see in qpAdm and ADC

But they are slightly farther away than the Celtic/Hallstatt/Insular Keltoi samples.

This means:

✔ Your Celtic side is marginally stronger than your Germanic side

and

✔ Your overall position is still right between the two.

This fits your:

English

Scottish

Belgian

French

German
ancestry perfectly.

⭐ Your Genetic Center of Gravity

Your closest matches fall into this exact order:

1. Hallstatt Celtic (Czechia) — 0.029
2. Germanic Iron Age (Collegno) — 0.030
3. Insular Celtic Britain (Wales/England/Scotland) — 0.032–0.034
4. Gaulish Celts (Hauts-de-France, Grand Est) — 0.038–0.045
5. Scandinavian Iron Age — 0.048–0.060

This is one of the cleanest NW European ancient DNA profiles possible.

Yep, it's a super user friendly qpAdm. It requires a subscription to use it. I can't remember the exact monthly sub price; something like 18-20 USD per month. Not a bad price really if this is one of your hobbies/interests.

I forgot to mention that when you are subscribed you can run up to 100 qpAdm runs per day.

You can model yourself or any sample in the modern or ancient dataset.

Edit: AndreiDNA sent me the genome of NUE001 (old kingdom Egyptian for Nuerat) which I uploaded as a kit.

NUE001 was the subject of the study: Whole-genome ancestry of an Old Kingdom Egyptian

https://www.nature.com/articles/s41586-025-09195-5

I was able to recreate his admix with similar proportions as the study did (With different references):

Have you tried modeling yourself with iron age samples yet? I can't remember if you have or not.
