I'm going to forward another letter I just posted on the message board
in answer to a question there from Mike. I think there are a few on
this list who are not on the CARROLL-L mail list and perhaps do not
use the message board. Mile asked:
"I do not know if one DYS# is more significant than the other as to
the probabaility of relations. After reviewing the kit chart, do you
think that Kit #31941 could be grouped near by the North Carolina
kits? Three out of the seven North Carolina kits match 30 of the 36
DYS#'s."
Below is the answer I posted back to him. Mike is a member of this
list if you wish to give him more information regarding his query, or
you could post it on the message board.

: Mike,
:
: I believe that your kit # 31491 is shown in the chart where it is
because the lines are listed by the order of the numbers. Yours
begins 13-23 and the men in orange begin 13-24.
:
: You were wise to compare with the lines in the orange group which
seemed to indicate an average. We don't know which of those was most
like the ancestor, since each lineage may have mutated in a different
direction. With only one exception, those men have not had a common
ancestor in about 200 years, so some mutation could be expected in
that period of time.
:
: I read somewhere, but can't find it right now that those DYS numbers
shown in RED at the top of the chart designated alleles which were
more apt to mutate than the ones shown in black. I think where the
mismatch occurs may make a small amount of difference in the percent
of probability that two men shared a common ancestor somewhere in the
past. That is why it is difficult to say exactly how two men are
related just by comparing the numbers.
:
: At
http://www.familytreedna.com/GDRules_37.html there is a chart
that gives the approximate relatedness based on comparing the numbers.
For a 31/37 match it says:
:
: "31/37 is too far off to be considered related, unless you can find
an "in-betweener' as for determining 'Only Possibly Related,' above.
It is important to determine what set of results most typifies the
largest number members of the group you are 'close' to matching. You
may be 31/37 with an individual, but 34/37 with the center of the
group, and your potential relatedness to him is through the center of
the group."
:
: Your best way to learn to whom you are related is by using the
personal web page provided for you by FamilyTreeDNA when they received
your kit. You need to be sure to set your preferences for that
display to include all Surnames and not just the Carroll surname. A
few men have discovered that they did not match a man of the same
surname at all, but they did match men of a surname which had lived
near their ancestors. Comparisons shown on that personal page should
take into consideration which markers are different between two men.
:
: We have three of the orange men who are extending the number of
alleles to 67. My cousin's kit # 32061 is due back about October 23.
You might want to consider extending yours to see if more of the
markers match in those 30 more alleles.
:
: Hope this answered your questions.
