stands for Short Tandem
Repeats. See the U.S. NIST's
of STR Loci Information.
2 - The allele values shown in this table use
Different testing laboratories use different approaches to counting
the DYS values. Be very careful to understand comparison
issues before comparing values from different laboratories.
Haplogroups are listed in green if the information was obtained from an
SNP Biallelic Marker test. ( SNP = Single Nucleotide Polymorphisms.)
Haplogroups obtained by prediction from STR Marker results are shown
in black. The alphanumeric haplogroup name is per the
DYS stands for DNA
Y-Chromosome Segment identifier
5 - DYS389 is a non-standard marker. Matching at DYS389 requires
when comparing markers reported by different laboratories. With DYS389I=13 and DYS389II=30, subtraction gives the
value for DYS389B=17. DYS389B is reported instead of DYS389-II
by some labs.
6 - These values represent the lab practices
post-19-May-2003, when the lab adjusted previous values these
Markers down by one point.
