admixtures

Hello Colleagues, I am researching my genealogy for more than 20 yrs and I decide getting into this DNA testing world. I have tested myself and my Mother (my father has already passed away) We did the FTDNA Autosomal Test and I am looking for some guidance on understanding the results. We...

The Copper Age was a period of transition between Neolithic societies and the Indo-European migrations. Although the Chalcolithic started in Neolithic Southeast Europe and Anatolia, it quickly spread to the Pontic-Caspian Steppe, from where PIE Steppe people expanded cross most of Europe and...

I have analysed dozens of ancient genomes using Dodecad dv3 and K12b and Eurogenes K36, and I noticed that almost every time ancient Scandinavians or Germanic tribes possessed non-negligible percentages of African admixture. These were sometimes reported as Central African or Northwest African...

I have had a look at Mesolithic and Neolithic genomes, an Early Bronze Age Yamna genome, compared Corded Ware vs Sintashta genomes, and analysed the Hinxton Celtic and Anglo-Saxon genomes. Here is another Corded Ware (or Battle-Axe) culture genome, but from Denmark instead of Poland., which I...

After analysing Mesolithic and Neolithic genomes and a Yamna genome, here are genomic admixtures for the Sintashta and Corded Ware cultures, two R1a-dominant north-east European Bronze Age PIE cultures. Keep in mind that the component names for the Eurogenes K36 admixture are not accurate and...

I have run a Yamna genome as well as the Iron-Age Celtic and Anglo-Saxon Hinxton genomes in the Eurogenes K36 calculator. Now is time to have a look at some Mesolithic and Neolithic Europeans. Keep in mind that the component names for the Eurogenes K36 admixture are not accurate and do not...

The Hinxton genomes were released in October 2014 and I already analysed their admixtures using the Dodecad dv3 and K12b calculators at the time. Here is another look at them using the Eurogenes K36 admixtures instead. It's a good opportunity to see which component of K36 correlate most with...

I should have done this a long time ago, but never found the time among the many things on my to-do list. I ran a Yamna genome in the Dodecad and Eurogenes calculators just to see what would come out of it, and to help interpret the maps I created from the Dodecad calculators. Keep in mind...

I have wonder for many years if "ethnic" or regional admixture are truly reflected in physical appearance or not. DNA segments used for genetic admixtures like those of Dodecad or Eurogenes do not necessarily contain a high percentage of genes affecting phenotypes. There could more of them that...

I've posted it before: the "science" behind so-called "admixture calculators" can't yet be called that. The validity of the output data is getting there, and will get there eventually, but it's not quite sufficient so that we can call the extant methods, "scientific." In other words, the...

There are interesting trends visible on PCA plot. Might be useful in determining historical population movement and mixing.

Tracing back Phoenician & Arabic DNA in modern Spaniards using Haak 2015's admixtures I have updated the genome-wide section of my Genetic history of the Iberian peninsula by analysing Haak 2015's admixtures (K=20). Haak et al.'s autosomal data shows that the Basques and other North Spaniards...

Here is the last of the three admixture maps based on Lazaridis et al. (2014) and Eurogenes. This map compares the genes of modern people to the DNA of a Mesolithic hunter-gatherer from the Loschbour cave in Luxembourg, who lived 8000 years ago and belonged to Y-DNA haplogroup I2a1b and mtDNA...

In order to make such maps we need a lot of data from all over the Europe. By the nature of this data collection it will be a self reporting project. It is not the best way, but it might be the only way to gather data for these maps. Please post your EEF, WHG, EEF numbers with place of birth...

There are plenty of autosomal calculators around (http://gedmatch.com/) and I have used practically all of them in order to identify any hint that would point me to the ancient Greek admixture. I will use data from the Dodecad project (k12b calculator) and concentrate on 3 populations who, I...

I thought it'd be interesting to visualise the distribution of the K10a's Red Sea admixture. It peaks in Ethiopia and Somalia, the region of origin of Y-DNA haplogroup E1b1b,and correlates fairly well with the distribution of E1b1b, except in northwestern Europe. Looks like E1b1b lineages were...

After the map of Gedrosian admixture I found it would be interesting to compare the distribution of the 'Caucasus' admixture in the same K12b. Although both peak around West Asia and South Asia, the frequency inside Europe is completely different. The Caucasian admixture looks more Neolithic...

Thanks to population genetics, we are becoming increasingly aware of just how mixed our ancestry really is. The old stereotypes about ethnic purity are meaningless when we think in term of genetic admixtures and deep ancestry spanning over 10,000 years or more. Yet, ethnic groups still exist...
