FTDNA Long form

FTDNA is starting to share their y-Haplogroup Long Form info again after hiding it last summer (shortly after they switched to reporting what they first called "Terminal SNPs" and what is now called "Short Hand")

This should be good news - but it is not.  Here's why:

  • ISOGG yTree

    • THE standard reference for the y-Haplogroup Tree (yTree)
    • Publicly available for all users - world wide
  • FTDNA yTree

    • Distinctly different from ISOGG’s yTree
    • Not available in tree form - publicly or to customers
    • Long form info now displayed with reported short hand on Project ySNP page
    • Unnecessary confusion

Here is my own long form - from both ISOGG & from FTDNA:

ISOGG:  R1b1a2a1a2b1b    http://isogg.org/tree/ISOGG_HapgrpR.html
FTDNA:  R1b2a1a1a1a3a4  https://www.familytreedna.com/public/barton/default.aspx?section=ysnp

Ugly!  Three differences in the first 6 digits and completely different after 9 digits - even to the point of not having the same number of digits (13 at ISOGG vs 14 at FTDNA)  Both versions are based on my short hand - R-L196.

So - be prepared for lots of questions and user concern.  Sigh.

Until FTDNA can arrange for ISOGG and FTDNA yTree alignment, they should hide their long form info.
