List of Y-STR markers

The Y-STR markers in the following list are commonly used in forensic[1] and genealogical DNA testing.

DYS454 is the least diverse, and multi-copy marker DYS464 is the most diverse Y-STR marker.

The location on the Y-chromosome of numbered Y-STR markers can be roughly given with cytogenetic localization. For example, DYS449 is located at Yp11.2 - meaning the Y-chromosome, petit arm, band 1, sub-band 1, sub-sub-band 2 - DYS449.[2]

Forensic labs usually use PowerPlex Y (Promega Corporation) and Yfiler (Applied Biosystems) kits that examine 12 or 17 Y-STRs, respectively. Genealogical DNA test labs examine up to 700 Y-STRs.
