This table reflects the
genetic distance between the participants results with their 25 marker
test results in. A distance of 0 is an exact match, a distance of 1 is
a single step mutation, etc.. By viewing the table on the 'Mills Y-DNA
Results' page and the table below we can conclude the following:
Matches - Kits 24485, 15692, 23751, 24485, 51048, and 35970
reflect a distance of
Therefore, they are an exact match which means you share a common male
ancestor with a person who shares your surname (or variant).
Match - Kit 5301 is reflects a distance value of 1, compared to 9421
and have a single step mutation in alleles 458. Since
458 is considered a fast moving
marker, these participants have a high chance of being related.
These tables reflect the
genetic distance between participant's yDNA results. The first number
reflects the genetic distance. The second number reflects the number of
markers compared (ie 12, 25,37, 67). For example, on the All
Participant Genetic Distance Chart:
When comparing Kits 35970 and 9421 the chart reflects that there
is a distance of 3 out of 37 markers compared.
Matches - When comparing Kits 23751 and 51048 the chart
reflects that there is a distance of 0 out of 37 markers compared. A
distance of 0 is an exact match.
About Mutation Rates
Family Tree DNA
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 magenta (on the results
tables) 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
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.
