Subject: [DNA] Ancestry Newly Identified DYS385 Numbers
Date: Tue, 03 Sep 2002 18:00:39 -0400


My Glennon Y-DNA project is with FTDNA. However, I also had my personal
Y-DNA done by Ancestry.com in order to get some insight on additional
markers.

Responding to a message from Emmett Mason, I recently went to my
Ancestry page and found that the values for DYS385 a & b had been
changed from alpha to numeric. I had not received any notice from
Ancestry that these changes had been made.

Ancestry reported these numbers as 11 and 14. Of course, I immediately
compared these results to the same markers from FTDNA. FTDNA reported
these as 11 and 16 for me.

In addition, FTDNA has processed more than thirty separate samples from
the Glennon group and 15 of them are 16 on DYS385 b; so, this 16 is not
a single observation. I am concerned by this difference.

Has anyone else been tested by both FTDNA and Ancestry.com who can tell
us whether the results are the same or different from these two
companies now that the alpha values have been translated to numeric?

Is there some reason that I am not aware of why Ancestry's numbers are
different from FTDNA's? Is there some adjustment to one of these
numbers that must be made to make them comparable?

I would appreciate any input that readers can give me. This is a
troublesome development.

This follows on the heels of a silent correction to one of my numbers
that Ancestry made in the past.
