I have been wondering about this for so long. Do those haplogroup mutations usually only occur in ONE of the father's sperm cells? So you can have two brothers in the same family carrying two different Y haplogroups, even if they are biological brothers by blood, both paternally and maternally...

Hi, I’m new to this forum. Please classify me. I can share my DNA results afterwards. Thanks. https://ibb.co/jW0JbSr https://ibb.co/YTbYWgZ https://ibb.co/NpR9xVH https://ibb.co/kJVYfgr https://ibb.co/ZGLhvCf

I have calculated the frequency of each of the main R1b clade in every region of France last year in order to update the R1b maps. I used Nevgen to determine the subclades of samples from FTDNA that were not confirmed by SNP testing. It seems that I forgot to post the table with the results, so...

So I tested my DNA with LivingDNA and got my results. Now I want to know what I can do with those results. I'm very interested in exploring my ancestry and history of my lineages. I will ask some questions and hopefully someone out there is able to answer them. Keep in mind that I am a complete...

After thinking about the genetic pre history of Europe, a question came to mind and I'm curious if anyone here knows. Is there any estimates on the population size of certain key periods in Europe's pre-history from archaeologists or geneticists. In particular I'm wondering how many farmers left...

Courtesy of Waldermar, Polish-Pomeranian member over at Anthrogenica. I found the similarity maps reminiscent of a Lazaridis paper. Also quite interesting, confirming some suspicions I have held. On whether all the samples are Slavic he replied: "In Radom, Grodowice and Detkovice, most...

Hi there, I succeeded in sequencing ancient autosomal DNA from a far relative, with a result of about 200'000 SNPs. But neither GEDMatch or other database accept this upload because they need almost 500k SNPs... Does someone know if there are worldwide databases to make random comparisons...

Here is the study. Nature Genetics: Identification of LZTFL1 as a candidate effector gene at a COVID-19 risk locus Abstract The severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) disease (COVID-19) pandemic has caused millions of deaths worldwide. Genome-wide association studies...

https://www.bbc.com/news/health-59140359 This new study, published in Nature, and led by researchers from the University of Cambridge alongside teams from Queen Mary University of London, University of Bristol, University of Michigan and Vanderbilt University, has discovered the brain receptor...

The study on ancient Etruscan DNA by Posth et al. 2021 showed that three Etruscan individuals were genetically closer to modern Northwest Europeans. Intrigued I checked their percentage of similarities with modern European populations using Eurogenes K36 and the map tool made by Jerome Hamon...

I have checked Ragnar Lothbrok's genealogy to find if he had male line descendants to this day. It would not be surprising considering that he had eight sons and they became powerful rulers of their own. The main issue is that the genealogy is disputed. If enough Y-DNA lines survived, it would...

Basically title. Has anyone used any of these services. I mainly wanted to get back in a Ketogenic diet, however being vegetarian in my country, trying to accommodate both is going to be really challenging. So before I do anything that drastic, I wanted to use my Autosomal file for...

There are two DNA testing companies founded over 5 years ago but that haven't made much noise in the pop gen community yet. Nevertheless they do look interesting. The first one is tellmeGen, a Spanish company based in Valencia offering both ancestry and health tests. Their website is available...

The work on the K12b admixture by historical culture gave me the idea to show the evolution of genetic admixtures over time by region. I have started with the Near East and East Mediterranean.

I have spent most of the last week calculating the the average values for the K12b admixtures for most of the ancient genomes tested to date. I thank Jovialis for providing me the genomes converted in the right format to run the K12b on Admixture-Studio. You will find the table in the page...

After Gaul, Italy, Iberia and Germanic tribes, here are the Dodecad K12b ancient British people from the Neolithic to the Late Bronze Age. I have calculated the average values (modal) for each period. I then compared these modals to modern populations using Vahaduo.

I have written a Genetic analysis of Ancient Iberia, in which I ran the Dodecad K12b admixtures for most of the good quality samples from the Neolithic to the Early Middle Ages and computed average values (a modal) by era. I then compared these modals to modern populations using Vahaduo.
