How to Interpret Your Results
Above are results from the laboratory analysis of your Y-chromosome. Your
DNA was analyzed for Short Tandem Repeats (STRs), which are repeating
segments of your genome that have a high mutation rate. The location on the
Y chromosome of each of these markers is depicted in the image, with the
number of repeats for each of your STRs presented to the right of the
marker. For example, DYS19 is a repeat of TAGA, so if your DNA repeated that
sequence 12 times at that location, it would appear: DYS19 12. Studying the
combination of these STR lengths in your Y Chromosome allows researchers to
place you in a haplogroup, which reveals the complex migratory journeys of
your ancestors. Y-SNP: In the event that the analysis of your STRs was
inconclusive, your Y chromosome was also tested for the presence of an
informative Single Nucleotide Polymorphism (SNP). These are mutational
changes in a single nucleotide base, and allow researchers to definitively
place you in a genetic haplogroup.
*NB: If your results indicate "null," this is a situation in which
the lab was unable to obtain a result for this marker (aka location) in your
DNA. Possible causes include a deletion in your DNA sequence that removed
the entire marker, or a mutation near the marker that causes the test to be
unable to "find" the marker in order to test it. While uncommon, this does
occur occasionally.
