Anne:

Thanks for the heads up. :-) So I looked over my shoulder and saw Bob
Birnbach coming on strong so I stepped on the gas and added the results
of two more YSTR markers -- DYF385S1 and DYF399S1. Don't ask me why they
named these markers with the prefix DYF instead of DYS. The scientists
on the list can talk to that part. I was told by Thomas Krahn that the
385 in the new marker name has nothing to do with DYS385a,b. Just a
coincidence the same number is used. Potentially very confusing if you
ask me. But he didn't name them the discoverer did. Thomas also said it
would have been better to name them DYZ. I initially for some reason
thought the F had something to do with the flanking region for the
DYS385 marker. My misunderstanding. So from my perspective, I agree with
Thomas that DYZ would have been a better prefix for the discoverer to
use if he needed a name change from DYS. Don't know why the person chose
not to use DYS.

I also understand from Thomas Krahn at DNAFingerprint.com, who did the
testing for these new markers, that they are multi-copy markers. Mine
results were 10-11 and 20-23-24.1 respectively. I'm only counting them
as one marker each at this point. I have updated my labmerge page to
show the 56 YSTR markers from eleven testing organizations. Here is the
