Y-DNA STR testing chart
This Y-STR testing chart provides comparative information on the Y-STR Y chromosome DNA tests offered by the major DNA testing companies. Y-STR tests are used for genetic genealogy within a genealogical timeframe and are generally co-ordinated through surname DNA projects.
For guidelines on DNA testing see the Genetic genealogy standards.
Single STR testing is offered by Thomas Krahn's company YSEQ. YSEQ also offers a selection of three Y-STR marker panels.
Y-STR testing was previously offered by AncestryDNA. This service was discontinued with effect from 6 June 2014.

- Family Tree DNA also processes tests for a number of affiliate companies: African DNA, iGENEA, DNA Ancestry & Family Origin and DNA Worldwide. Participants who join Family Tree DNA's database from these companies will have kit numbers that begin with 'A' from African DNA, 'E' from iGENEA, 'M' from DNA Ancestry & Family Origin, and 'U' from DNA Worldwide. National Geographic Genographic kit transfers begin with 'N'. Family Tree DNA acquired DNA Heritage in April 2011. DNA Heritage customers were given the option of transferring their results to the FTDNA database. DNA Heritage kit numbers begin with the letter 'H'.
- Limited to only when ordering a test and joining a project at the same time. Some projects may not allow this level of marker ordering.
- Family Tree DNA offers a test cost discount when ordering a test and joining a project at the same time
- Additional markers may be ordered through Family Tree DNA's Houston-based Genomics Research Center.
- FTDNA customers can purchase custom SNPs for $39 per SNP.
- If the haplogroup cannot be predicted with confidence FTDNA will test a backbone SNP panel to identify the haplogroup assignment. For further details see the FTDNA FAQ What is the SNP assurance program?
- About the Family Tree DNA database. Accessed 28 October 2013.
- Customers who have tested with companies using the Sorenson Genomics Lab (AncestryDNA GeneTree and Sorenson Molecular Genealogy Foundation) can transfer their results to the FTDNA database for a small fee. Third-party kit numbers are preceded with the letter B. For further details see: http://www.familytreedna.com/faq/answers.aspx?id=41
- Additional markers may be ordered through Genebase. Pricing varies with each step, 20 to 44, 44 to 67, 67 to 91. There does not seem to be a method of marker upgrade which skips a level of markers tested. For example, 20 to 67, 20 to 91 or 44 to 91 without paying for each individual step in a marker level upgrade.
- The SNP test is a haplogroup backbone test which looks at between 7 and 47 Y-SNPs to provide further resolution. See the Genebase store for details of the number of SNPs tested in each haplogroup.
- Genebase launched in 2005. Genetrack Biolabs launched in 1998. (http://www.genebase.com/about/?p=3)
- An upgrade from 15 markers to 65 markers is available for £369 (US $574
- There is a sliding scale of project-based fees from £145 (US $226) each for 5-10 members to £135 (US $210) each for 21-30 members.
- Oxford's Y-Chromosome database was once partially accessible to the public. When partially accessible, the database was viewable, but only Oxford customers could add to it, and contact any matches. Now the database is closed to all but Oxford's customers. An extra layer of security was added requiring you have a customer number. This allows you to receive a database access code.
