A Y-STR is a short tandem repeat (STR) on the Y-chromosome. Y-STRs are often used in forensics, paternity, and genealogical DNA testing.

[edit] Nomenclature
Y-STRs are assigned names by the HUGO gene nomenclature committee.
Some testing companies have different formats for the way STR markers are written. For example, the marker DYS455 may be written as DYS455, DYS 455, DYS#455, or DYS# 455. The scientific standard accepted by HUGO and NIST is DYS455.[1]
[edit] DYS
DYS is jargon once used in genetic genealogy for a Y-STR. Its origins may be due to the most common first three letters of a Y-chromosome DNA STR (short tandem repeat).

In genetic genealogy, the following is a list of sponsored databases containing publicly submitted surnames and Y-STR haplotypes:
