Y-Haplogroups and migration, using the example of I-L38 > BY14026

In April 2017, I did my first Y-DNA test and was surprised by the result. My parents come from Almopia in the north of Greece, but the Y-Haplogroup I-L38 to which I belong originated about 4500 years ago in northwest Europe, between the mouth of the Rhine and the Baltic Sea. Since then I have been studying the question of how this haplogroup came to Almopia and have already motivated some relatives and carriers of my subgroup Y125026 to do Y-DNA tests to get a clearer picture.
The aim of this article is to present the information available so far, in simple words and pictures and to bring the topic closer to people from Almopia, as well as carriers of the I-L38 subgroup BY14026. In addition, it is intended to motivate these people to use NGS (Next Generation Sequencing) tests, such as the Big Y of Family Tree DNA, as this will lead to a clearer picture of where our sub-branches originated and the path they took.

I-BY174585 Haplogroup: From Norway to England and Spain through Norsemen and Crusaders.

The haplogroup I-BY174585 is a branch of the I-L38 haplogroup. This latter is characterized by being less populous than others haplogroups formed in the same age and distributed (across Europe) from Volga River to Western Iberia in East-West way and from Scandinavia to Sicily and Greece in North-South way.
The haplogroup subject of this study has only three confirmed members from different countries. This latter feature is according with the nature of the haplogroup father except for its young TMRCA of 1825 years ago.
The target of this study is to collect the personal history of the three families who belong to the I-BY174585 (group) and explain their relationship through the History of Europe in the last two millennials.

Prepare the BAM file for YFull, from a WGS

You don’t upload the raw data BAM file of the NGS test to Yfull yourself, but indicate where it can be downloaded. You can get the link from the provider where you did your test. (FTDNA, YSEQ, FGC). Companies like Dante Labs don’t offer such a link for Yfull directly, so you have to make the required file accessible via a cloud.

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 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-SNPs and Y-STR of I-L38>>BY14026

The diagram shows the subgroup I-BY14026, the Y-haplogroup I-L38.
This was originally created to get an overview of the SNPs which, are used for the age estimation of on the one hand and can be ordered at on the other hand. The tables contain the name for each SNP, the HG38 position with value (ancestral and derived), and the information if these are used for the Y-haplotrees of FTDNA and YFull.
