Thanks for the explanation. Ed

Hi Ed, ? There are three relevant processes here: ? (1) Quality controls on individual SNPs. The quality required for variants to be entered on the haplotree is higher than the quality of the

Ed, I thought you said that the varianti was shared by two kits. If that is true, and the marker is not on the tree, the most reasonable inference is that FTDNA have not deemed it phylogenetically

Vincent, I agree that FTDNA does not use every variant for haplogroups. However, to say that if it was reliable it would already be on the tree is not correct, in that a variant has to be shared

23andMe put out a blog post several months ago about the issues they found with their variant assignments: https://blog.23andme.com/articles/23...up-assignments (

Not all “non-matching variants” are suitable candidates for use as phylogenetic markers. So I would not make that assumption. FTDNA evaluates the performance and reliability of the markers, so if

Currently, three of us share haplogroup FTB93230 and the most recent of us to test just got his final Y700 results. Per my BigY matches, each of the other two do not match me on three private

Hello everyone, About a month ago, I logged into my 23andMe account and was surprised to see that they had reassigned my paternal haplogroup assignment from R-Z156 to R-M405 (aka R-U106). I reached

Hi Shane, Yes, indeed, it is entirely possible to check the status of an aDNA sample for SNPs of known downstream clades of R-FGC17460. This can be done from the BAM file (hg19 or hg38?), or by

Ewenn,Thanks for the heads up on the new paper. I've already read most of it. It's pretty cool to read about a burial that is part of my paternal lineage. If I understand correctly, KO015 also had the

Thanks Ewen, it is really interesting. I saw yesterday evening the update done by FTDNA on discover tree, adding Koksijde 15 downstream R-FGC17460 (

Hi Bertram, all, A new paper concerning this study and these aDNAs was recently published:

" Apparently, the number of BigY tests processed by FTDNA has been a surprisingly constant *47* tests per day for the last three years." BigY testing had a nice uptick last "month". June 5? 111,760

I’d quibble with the use of the term “descendants” in the title. The deceased may be collateral relatives of GW, but GW has no documented descendants…

Interesting,Through my paper trail, George Steptoe Washington, nephew, is my 4th cousin five times removed through my Dabney/Maupin connection. I think MANY, MANY are descended from some of those
