Statistics for the I-M170 Y-haplogroup I-L38 and subgroup I-S2606 (End of 2024)

The I-L38 tree is growing and new testers are constantly being added. In the past, the standard test for Y-DNA at FTDNA was the STR test, with 12, 25, 37, 67 and 111 markers, and the Y-haplogroup was and is only predicted with I-M170. Other suppliers also had and still have panels with a different number of markers, e.g. the PowerPlex® Y23 or the Y-STR panels from YSEQ. Even Ancestry.com initially offered Y-STR tests that could be uploaded to FTDNA. With adequate Y-STRs and some experience, you can predict the Y-haplogroup a little deeper than with FTDNA (I-M170) and for a while it was common to verify this with single SNP tests or SNP packs. Nowadays you can choose the same procedure, but in my opinion it is more reasonable to buy an NGS (Next Generation Sequencing) test, which is now affordable. At FTDNA this is called Big Y700, with other providers you can do a WGS and upload the relevant data to YFull.com.
For my research, but also for the FigUre tree, I have collected our I-L38 cousins from all possible databases and want to show a few statistics here. Sometimes you have to add apples and oranges together, as it is not easy to summarise data with different levels of information, but you still get a small overview.
