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 ...
