First fruits from Greece of the Family Finder Y haplogroups destination for I-S11321, ancestor of I-L38

In the middle of last year, FTDNA announced that they had decided to directly report the Y haplogroup using the Y-SNPs tested in the Family Finder. After the first results also came for I-L38, I wrote the article Family Finder Y-DNA Haplogroups, in which I showed what this could mean for our Y-haplogroup. Now the time has come.
In addition to a known tester from Portugal (already a member of the I-L38 project) and a few unknowns, a tester from Greece has appeared in FTDNA’s Y-DNA haplotree. This is the great advantage of the Y-haplogroup determination of the autosomal test Family Finder. In contrast to 23andme and LivingDNA, where such testers disappear without a trace, with FTDNA they are also shown in the Y-tree. Unfortunately, you can only see them and have no way of contacting them. An internal FTDNA messaging function would be an advantage here.

Family Finder Y-DNA Haplogroups

In the autosomal tests from 23andme and Living DNA, the Y-haplogroups have always been displayed directly, whereas in the autosomal tests from My Heritage and Ancestry, the Y-haplogroup can only be extracted from the raw data using tools such as the Morley Predictor or the YSEQ Clade Finder. This was not previously possible with FamilytreeDNA’s Family Finder, as the Y-SNPs were removed from the raw data, making it the only autosomal test that did not contain any information on the Y-haplogroup. I had already described this in the article Y-haplogroup from atDNA raw data. This is now changing, as FamilytreeDNA has decided to directly report the Y-haplogroup using the Y-SNPs, tested in the Family Finder. In this article, I will use my own Y-haplogroup I-L38 to show what this means and what advantages I hope to gain from it.

I-M170 and the Babylonian confusion of Y-Haplogroup names

The child needs a name!
A clear one! An unmistakable one!
A Y-Haplogroup is a group of men, all descended from one man, a “forefather “, in a purely paternal line. We want to give this forefather a name and there are two different ways of doing this, both of which have their pitfalls and can lead to great confusion. The aim of this article is to show the possibilities for naming and the confusion potential.

YFull – First Steps

Yfull is not a provider of Y-DNA or NGS tests, but an analysis service for NGS with a database in which data from NGS tests are compared and analyzed, regardless of the provider. This allows to compare the results of currently 13 sources. (Commercial companies and scientific studies). The results are presented in the form of a Y-tree in different representations. The kits are presented anonymously and the Y-tree (as well as the mt-tree) is publicly accessible for everyone. This makes it not only an enrichment for the submitters, but also for everyone who is concerned with the topic Y-tree (as well as mt-tree).

Verify relationship in paternal line, with known terminal SNP and private „novel“ SNPs from NGS

f you wanted to compare the Y-DNA of two men, you used Y-STR tests with as many markers as possible. If one or more NGS (Next Generation Sequencing) are available, a new method can be used to determine the relationship of two men in a purely paternal line using “young” SNPs. Your youngest SNPs are those that have only been detected in your sample. These are called “Novel SNPs” or “Private SNPs”.
This method is made possible by the company YSEQ.net and the possibility to actually test any SNP that can be tested with the Sanger method for little money after you “wish” for it.

Y-haplogroup from atDNA raw data

In the autosomal DNA tests of 23andme and Living DNA, the Y-haplogroup and the mt-haplogroup are displayed directly. Many don’t know that the raw data, of all male atDNA testers contain information (Y-SNPs) for the Y-haplogroup and can be extracted with tools like the Morley Predictor. (Only FTDNA removes these Y-SNPs from the raw data).
Irrespective of which company the atDNA test was done with, it makes sense to have a closer look at the results, because there is much more information in it than some people think. If you get an “old” haplogroup displayed, even though younger branches are tested, it can mean that you are sitting on a rare branch.

NGS – Take part at the Y-tree

Since my first Y-DNA test I have been fascinated by the Y trees. That’s why I support these projects and have already contributed some NGS. In the beginning I couldn’t imagine much of it. What, when, where and why happens this and that? In the meantime, I can answer some questions. Here is a small overview of what happens when you participate in a Y-tree.
But there are also a few more ways to support haplogroup projects. By donating, even if it is “only” the raw data of the existing test.

Y-DNA, Haplogroup and Genealogy

Y-DNA, Haplogroup and Genealogy

When it comes to verifying paternal relationships over several generations, the Y-DNA test is the right choice. My own concern is to verify a family legend that says that my fatherly ancestor came from a certain area of Greece about three hundred years ago. Here you can’t get any further with atDNA. The selection of tests for Y-DNA is extensive. Depending on the motivation for such a test, there are different approaches.
