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:



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.

you need a continental celtic pop for gallic ancestry (i used R2055.SG + NOR2B6.SG ). also I'd use Scotland_IA for insular celtic. definitely an overestimate


These were the right pops i used for a personal iron age model on myself:
Mbuti.DG, Czechia_IA_LaTene.AG, France_MN.AG, Germany_Tollense_BA.SG, Switzerland_EBA_1.AG, England_EIA.AG, France_Alsace_Lingolsheim_EBA.AG, France_N.AG, France_Occitanie_IA2.SG, Germany_BellBeaker.AG, Germany_Saxony_LBK_N.SG, Hungary_IA_LaTene.AG, Latvia_BA.AG, Sweden_IA.SG, England_IA.AG, England_MIA.AG, Sweden_IA_2.SG, Sweden_Viking.SG, Switzerland_LN.AG, Sweden_Mesolithic.SG, Norway_North_Pre_Viking.SG

It took quite a few attempts and basically, I had to use Scotland LIA instead of Scotland IA. This is my result with your references:

germanic looks about right considering your ancestry but i think insular celtic is too low

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

I'm still experimenting with your references. Using Scotland EIA bumps up the Insular.

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.

I just watched AndreiDNA's video (the one you posted). It's actually a very clever idea. My apologies for criticizing his method.

Here's a couple more:





And this one is with French Bell Beakers. Different references though.

model with scotland_mia looks very solid
