List of Y-STR markers
The following list of Y-STR markers 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] For a nearly complete map of the position of Y-STR markers have a look at Ymap from Family Tree DNA.
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 442 Y-STRs.
Mutation rates
Mutation rates are those per generation, as estimated in Chandler (2006).[3] The quoted estimated errors are typically +/- 15-20%. Alternative estimates (for forensic use therefore not all markers are covered) from observed pedigrees are also available at the Y Chromosome Haplotype Reference Database.
It appears that some trinucleotide markers may have much higher mutation rates at some repeat lengths than at others. For example, variation of the trinucleotide DYS388 is generally very slow in most haplogroups, when it takes the values 11-13. But there appears to be much greater variation and more rapid mutation in Haplogroup J, where it typically has values 14-18. Similarly the trinucleotide DYS392 is reported to be "fast" in haplogroups N and Q, where it takes values 14-16 which are rare in other groups.[4]

| DYS425 | DYS425, when it can be measured, is very stable. However it is actually one copy of a multiple part marker, DYF371 (below), and as such recLOH mutations can often make it unmeasurable when the other copies overwrite it. For example, it is associated with the defining SNP for I-M38 (I2a2a1a1; formerly I1b2a1), as the SNP M284 can render a null value at this marker. Most members of E-M96 and sub-clades also render null values. Nevertheless it was one of the small number of markers originally offered by Oxford Ancestors, and Family Tree DNA later chose to offer it to genealogists also. | TGT | 10-15 | [5] | |

DYS464 |
DYS464 is a multi-copy palindromic marker. Men typically have four copies known in such cases as DYS464a, DYS464b, DYS464c, and DYS464d. There can be less than four copies, or more, which in such cases would be known as DYS464e, DYS464f, etc. DYS464 is the most diverse range of values of any Y-STR marker (source). This marker can also sometimes be typed with separate g-types and c-types to increase resolution. The type variance is based on a SNP that can be found in most R1b haplogroup males. It is part of the Palindromic region of Y DNA | CCTT | 9-20 | 0.00566 | Forensic value of the multicopy Y-STR marker DYS464 |

Y-STR allele nomenclatures
DNA testing companies or labs in certain cases use different nomenclatures to designate the same Y-STR allele. Thus, a conversion must be applied in these cases to accurately compare Y-STR results obtained from different companies. The most common nomenclature is based on guidance provided by NIST for Y-STR markers historically reported differently by various companies. The NIST standard is the proposal of ISOGG (International Society of Genetic Genealogy) for genetic genealogy companies.[6][7]
