Notes for understanding the Emerson Results Page
A good explanation of the theory of DNA analysis is provided at the following website:
Please consult one of the Administrators before ordering a test kit.
Participants who join surname group projects receive kits at a reduced cost.
There are two unassigned kits available through the Emerson project Administrator.
Please contact Leon Amerson (e-mail contact below) to reserve one of these kits
* * Results for participants are reported using identity number assigned as results are received,
then under the name of the earliest known ancestor, as determined by research.
*A value of 0 for any marker indicates that the lab reported a null value or no result for this marker.
All cases of this nature are retested multiple times by the lab to confirm their accuracy.
Mutations causing null values are infrequent, but are passed on to offspring just like other mutations,
so related male lineages such as a father and son would likely share any null values.
QUOTE from information provided by Family Tree DNA:
"DYS 19 is also known as DYS 394."
"It is obvious from our observation of 1000's of samples that some markers change or
mutate at a faster rate than others. While that actual 'faster rate' has not yet been definitively
calculated, not all markers should be treated the same for evaluation purposes.
The markers in red have shown a faster mutation rate then the average, and therefore these
markers are very helpful at splitting lineages into sub sets, or branches, within your family tree.
Explained another way, if you match exactly on all of the markers except for one or a few of the
markers we have determined mutate more quickly, then despite the mutation this mismatch only
slightly decreases the probability of two people in your surname group who match 11/12 or
even 23/25 of not sharing a recent common ancestor."
NOTES CONCERNING OUR CHART:
Numbers in red on yellow background indicate markers which tend to mutate at
a significantly faster rate than those marker numbers (DYS #) which are black on blue background.
Differing genetic markers within a group are highlighted in yellow.
Participant results, at present, are grouped by shared Haplogroup.
Differing markers between individuals, within a group, are highlighted.
The probability that two participants in the study share a common
ancestor becomes more likely when all but 1 to 4 marker values are a match.
For those markers that mutate more frequently, a marker value differing
by +1 or -1 has only a small affect on the probability of relationship.
