Y-DNA STR testing comparison chart

From ISOGG Wiki

(Redirected from 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.

Some surname DNA projects offer sponsored Y-DNA tests. To see if your name is included on the list visit our free DNA tests page.

For background information on purchasing a DNA test see Before You Buy and Choosing a DNA testing company.

For guidelines on DNA testing see the Genetic genealogy standards.

For information on Y-SNP testing and SNP discovery see the ISOGG Y-DNA SNP testing chart.

Note that Y-STRs are also included with Y-chromosome sequencing tests such as the BigY-700 test from FamilyTreeDNA and the Y-Elite from Full Genomes Corporation.
