More Chaos

FTDNA just started providing their long form haplogroup again. 

  • FTDNA's Haplogroup tree is different than it used to be and different from what ISOGG provides.
  • FTDNA is reporting quite a few long form Haplogroups on their ySNP view in their Project Public pages and in the GAP - with a good number of the T-SNP format mixed in.  Sometimes, the long form is also in the Results table info for yDNA.  There is no consistency.
  • FTDNA is now calling the "Terminal SNP" by another name.  It's now "short hand" on their ySNP page.and "Haplogroup" on their yDNA results page.  That's good news in one respect, as "Terminal SNP" was a particularly confusing label - as it is clearly not anyone's true Terminal SNP.when they have an estimate and is probalby not their Terminal SNP when they have been Deep Clade SNP tested.
  • Ironically, things were less difficult when FTDNA was not providing their long form Haplogroup at all - as then, it didn't matter which differences they had with the ISOGG tree.  Now, the differences will be quite confusing - particularly when they sometimes report the "short hand" and sometimes report the long form. 

WorldFamilies will continue to post the T-SNP (short hand) from FTDNA and the Long Form Haplogroup from ISOGG.   We'll soon change the label to reflect FTDNA's new name for the "T-SNP" - "Short Hand"

To give one example of how different ISOGG & FTDNA are these days, here is my long form Haplogroup from both organizations:

FTDNA: R1b1a1a1a1a4a4
ISOGG: R1b1a2a1a2b1b

We can only hope that they will align soon

Long Form Haplogroup

SNPs are confusing enough what with all the different designations such as S, M, FGC, PF, etc. Why do the Powers-That-Be make it even more confusing by sticking to the constantly-changing long forms? What is necessary about them? I have cleared them from my projects in favor of T-SNPs (or shorthand) and am using the space to show who has tested for which advanced SNP test--G2 (Geno 2.0), Ch2 (Chromo2) BY (Big Y), and FGS (Full Genome Scan).

Long Form and Short Hand

Paul, you have done such a nice job of administering your Byrne project through the years that I can only compliment your work.  Identifying who has done an advanced Deep Clade test is a great touch.

I can't speak for others - but for me the key to dealing with SNPs is to be able to look at a Lineage and know which is the most recent SNP.  Without a long form reference, there are two choices: memorize the SNPs (who can do that for more than a very few Lineages?) or look it up (and I do that at ISOGG frequently) 

My Results Tool checks ISOGG every night to identify any additions to their tree the previous day.  When ever a WorldFamilies Results page is updated by our Tool, it has the Short Hand identified by FTDNA and the corresponding Long Form from ISOGG.  That provides both options to folks.  And - the page scroll is set to freeze the kit number and earliest ancestor, so the wide column with the long form is the first to disappear when you scroll right.  The marker labels are also set so that they continue to display as you scroll down the page.

It seems like every few weeks, the browsers take turns providing the best view and the worst one.  The other day, Internet Explorer was providing the best display of our Results pages that were prepared by the Tool
