There were some conversion factors between some of the EA YSTR18 and
DNA-Fingerprint (now FTDNA DNA-FP Panel 9) tests of the same markers. I
haven't looked at this for a few years now though! :-( I tested the EA
YSTR18 myself so that I could be sure of conversion factors. I'll try
to find the emails from EA, but they are probably lost now. :-(

In an earlier post I mentioned a difference between the YSTR18 and FTDNA panel 9 but this was due to a conversion that I did and I am sure I didn't decide a conversion by myself (even if I can't recall how I was prompted to do it). So, no differences between YSTR18 and FTDNA panel 9 but, may be, some old , wrong entries from some times ago.

Vince reported 2 cases of 556=12 in R1b (1 being mine) and I am wondering if early stages of R1b may have DYS556=12 , a little bit like the changes on DYS426 (opposite direction).
