INTERPRETING GENETIC DISTANCE WITHIN SURNAME PROJECTS |

Your perfect 12/12 match means you share a
common male ancestor with a person who
shares your surname (or variant). These two
facts demonstrate your relatedness, however
if your name is one of the most common
surnames, i.e. Smith, Tailor, Miller, etc,
(trades or towns) then we always suggest you
utilize additional markers to eliminate the
possibility of a coincidental surname and
genetic match. |
1 |
Possibly Related |
You share the same surname (or a variant)
with another male and you mismatch by only
one 'point' on only one marker. For most
closely related or same surnamed
individuals, the mismatch markers are either
DYS 439 or DYS 385 A, 385 B,389-1 and 389-2.
To ensure that the match is authentic you
should utilize additional markers. |
2 |
Probably Not Related |
You share the same surname (or a variant)
but are off by 2 'points' or 2 locations on
just 12 markers. It is only possible that
you and another related family members' line
each have had a mutation. There are two ways
with DNA testing to confirm or deny. One is
to test additional family members to search
for a line that shows a mutation that is 1
point closer to your sample. The other is to
test additional markers. Refining greatly
enhances science’s ability to determine
relatedness -- geared towards the most
accurate assessment of the number of
generations to a shared ancestor. Only by
further testing can you find the person in
between each of you...this in 'betweener'
becomes essential for you to find, and in
their absence we feel you are not related. |
3 |
Not Related |
9/12 - is too far off to be considered
related. Unlikely but vaguely possible that
the rule for Probably Not Related applies. |
4 |
Not Related |
8/12 - You are not related and the odds
greatly favor that you have not shared a
common male ancestor with this person within
thousands of years. |
5 |
Not Related |
7/12 - You are not related and the odds
greatly favor that you have not shared a
common male ancestor with this person within
thousands of years. |
>5 |
Not Related |
You are totally unrelated to this person. |
