I am paternal (Y) R-L45. I was born and currently live IN SCOTLAND of both mainland Scottish men and ORCADIAN (i.e. PICTS + VIking/Norwegian) men from Westray, Orkney.? Our family is still there and

Scientists crack mystery of how MS gene spread The DNA of ancient cattle herders has revealed how diseases evolved in Europe over thousands of years. Read in BBC News:

Hi Ray, all, The question of the reliability of SNP test results is certainly a crucial point, especially since these tests constitute more than half of R-U106+ tests in the FTDNA's database. FTDNA

I would like to second what Raymond said. When I imported my Genographic 2.0 results into FTDNA (in 2016), my Y-SNP tree was littered with false positives outside of my branch. I also suspect that

The chip-based testing all autosomal tests rely upon is not perfect. False positives and false negatives are known to occur within these tests. I don't remember off-hand how high this error rate is,

Thanks Iain. I have linked them all to my FTDNA tree, as painful as that tree is to work with. I'll see what I can do about getting them to upload VCF files but many of them haven't even given me

Hi Mike, Thank you very much for the summary. It's good to hear to hear about the times when people are successful - these case studies both give ideas to others, and help those of us working at

New Ancient Connections have been added to FTdna's Discover tab. For my father's line it is at R-Y7378: Vor Frue Kirkeg?rd 454 1536 - 1806 CE Shared Ancestor 1050 BCE You and Vor Frue Kirkeg?rd 454

Thanks Ewenn. This has been really useful. One of my Tryon BigY project members recently did the 23 and me test and was assigned R-FGC14877 so it looks like they may be using the same chip as FTDNA.

Thanks Ewenn! -- Kevin Terry

Hi all, Thanks to the spreadsheet shared by Vince (whom I thank very much for this) on another topic, I was able to search for the Y-SNPs, and the corresponding haplogroups, downstream of R-U106,

According to the same principle as the example above, we could even imagine the hypothesis where an FF test would match one of a tester's PVs, provided that the position of this PV is covered by the

Thanks again Vince for sharing this, you allowed me to solve a mystery concerning the appearance of FF / Y-SNPs testers in a haplogroup: In fact, it is the SNP FGC57405 (not listed in this file,

The spreadsheet contains all 10,577 rows of the raw data that FTDNA is providing, which are the same across all haplogroups. ?Several positions are listed multiple times, which is why the number of

Thank you Vince for sharing this. I suppose even more than that because certain haplogroups downstream of R-U106 on which new FF / Y-SNPs testers have been added, have no equivalent SNP appearing in

Hi Kevin, The requested map (at countries level - data as it in FTDNA's Discover, id est without any correction), current version (2023-12-16): R-FGC13326 European map (

There appear to be about 9,000 unique Y-SNPs on the current FTDNA chip. https://docs.google.com/spreadsheets/d/1nyycup1kcfpi2D0iZZJhaJlvPIexDELeXdfRnxkS6JQ/edit?usp=sharing Vince

For all practical purposes, from a MyHeritage autosomal test, I was able to extract from the 3495 Y-SNPs covered by the chip used, 49 SNPs appearing in the clades downstream of R-U106: *RSID* *Name*

Hi Ewenn, You previously produced a map for FGC13326. I would be curious to see an updated map to see if there are any changes! Thanks -- Kevin Terry

Thanks John. Given that I'm applying statistics to small numbers, we come pretty close to the expected distribution. # SNPs # occur freq 300 yr prob 0 0 0% 0% 1 0 0% 1% 2 0 0% 2% 3 0 0% 5% 4 1 1% 8% 5
