Y-DNA SNP testing chart
This Y-DNA SNP testing chart provides comparative information on the Y chromosome SNP tests offered by the major DNA testing companies. For information on the Y-STR tests used for genealogical DNA matching purposes within surname DNA projects see the Y-DNA STR testing chart.
For background information on purchasing a DNA test see Before You Buy.
Currently the chief utility for genetic genealogy lies in ruling out false positive matches for similar Y-STR haplotypes, particularly if the haplotype is close to the modal haplotype for the haplogroup subclade.
Rapid strides in SNP discovery have the potential to bring the deep ancestry time frame forward considerably, perhaps even to the familial level, with more specificity for geographic origins. These have in the past happened through the Walk Through the Y sequencing program at Family Tree DNA under Thomas Krahn. They are currently moving forward through Family Tree DNA's BIG Y test under Dr. David Mittelman and through the Full Genomes Corporation.

- The companies now trading as BritainsDNA, ScotlandsDNA, IrelandsDNA and YorkshiresDNA were formerly known as Ethnoancestry.
- 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'.
- Prices checked 25 Oct 2013; check company websites for current prices.
- $299 when interpretation and narrative report should be included. May be purchased in combination with other products and reports. The company also offers a standard Y-SNP test for $265. This test looks at 300 Y-DNA SNPs and includes a narrative report.
