Subject: [DNA-R1B1C7] DYF399X modals
Date: Sat, 15 Mar 2008 11:00:12 -0600


I wonder if anyone knows if modals have been estblished for DYF399X in
R1b1c7. As many of you will recall, the Ewing project has a large
(genetically) closely related group of men in several (conventional)
kindreds not known to be related to one another. We have been testing some
of these men for DYF399X, hoping to find a way to distinguish these kindreds
genetically, because the 67-marker panel is just not doing it. I will paste
a summary of our results below (though I wonder what will happen to the MS
Word Table when the formatting is stripped out), and if any of you are
interested in more detailed discussion of this, drop me a line and I will
send you a copy of a report I've just written on the subject.

Meanwhile, we are finding that our men are more or less evenly split between
25c and 26c at the middle allele of DYF399X. It would be interesting to me
to know which of these values is ancestral, and I am thinking that if there
is a clear modal in R1b1c7 for this marker, that would be the ancestral
value. Does anyone know this? I welcome other comments, as well.

Note that JMc is R1b1, but not R1b1c7, and is not closely related to the
others in the table.
