What do the numbers in the Y-DNA DYS section mean?
The numbers found on this page are the key to comparisons made between males in our database. The Y-DNA markers are displayed in this section. You will see that the first column is for the loci, the second for the DYS number (that’s Designated Y chromosome Segment) and the third for alleles (which are the values we use for comparison). This is how we present the results that are determined from your sample. The loci is the location within the Y-DNA 12, or 25, 37 or 67 markers that we test, and the DYS number is the name assigned to that particular location on your Y Chromosome that we have tested. Everyone who tests will be tested for the same loci and DYS numbers. The allele values, which represent your results, are the numbers that are unique to you and are used in the comparison against others.
