STR Marker Values for R1a-Y2619 Ashkenazi Levites

Posted at the bottom of this page is an Excel Sortable Spreadsheet of Short Tandem Repeat (“STR”) marker values for R1a-Y2619 Ashkenazi Levites. (You can download the Sortable Spreadsheet by clicking on the arrow to the right of the link at the bottom of the page.)

The first page of the Sortable Spreadsheet provides STR marker values for the R1a-Y2619 Ashkenazi Levites who have received 37-, 67-, or 111-marker results from Family Tree DNA through STR testing. The second page of the Sortable Spreadsheet includes 561 or 838 STR marker values for the men who have done Big Y-500 or Big Y-700 testing through FTDNA, respectively.  

The Sortable Spreadsheet also provides Y-DNA clusters and subclusters for R1a-Y2619 Ashkenazi Levites who have done full Y-DNA testing, as well as predicted Y-DNA clusters and, sometimes, subclusters for R1a-Y2619 Ashkenazi Levites who have not yet done full Y-DNA testing. 

The Sortable Spreadsheet may be used to analyze the relationship among R1a-Y2619 Ashkenazi Levites. Instruction for performing such an analysis, either manually or in conjunction with the Steps to Matches spreadsheet also posted at the bottom of this page, are posted on the Using the R1a-Y2619 Ashkenazi Levite Spreadsheet page of this website. (That page of the website posts a sample analysis using the Sortable Spreadsheet showing how the methodology works.) 

Also posted at the bottom of this page is an Excel spreadsheet, created using the Y-Utility program, that shows the number of genetic steps between each R1a-Y2619 Ashkenazi Levite. This Y-Utility spreadsheet includes a page that provides essentially the same information concerning marker values as FTDNA project pages, along with three pages that show the genetic distance of each R1a-Y2619 Ashkenazi Levite from each other (and from the R1a-Y2619 Ashkenazi Levite mode) at 111 markers, 67 markers, and 37 markers. 

This website previously posted a Y-Utility spreadsheet that calculated the time to a Most Recent Common Ancestor ("MRCA") (in years and generations) for all R1a-Y2619 Ashkenazi Levites who have tested to 111, 67, or 37 markers; click here to learn why that spreadsheet has been retired.

Further information concerning the Y-Utility spreadsheets is posted on the Using the Y-Utility Spreadsheets page of this website.

This website also posts a table that shows: (1) how frequently specific STR marker values mutate, according to Family Tree DNA and a 2010 study by Burgarella, et al.; and (2) the percentage of deviations from the R1a-Y2619 Ashkenazi Levite mode for each STR marker (the current version of that table is included in the Sortable Spreadsheet posted at the bottom of this page). Note that a high percentage of deviations from the mode on a marker may reflect either: (1) fast-mutation rates on the marker; or (2) a mutation on a slow-mutating marker that occurred long ago, resulting in a major split on the R1a-Y2619 Ashkenazi Levite family tree. To assist in analysis of this issue, the website posts another table that ranks, in numerical order, the frequency of deviations from the mode among R1a-Y2619 Ashkenazi Levites.

Finally, instructions concerning use of the sortable spreadsheet and other materials to analyze other Y-DNA clusters are posted on the Adapting the Sortable Spreadsheet and Using Online Utilities page of this website.

Periodically, and as warranted by the receipt of new or updated test results, new versions of the Sortable Spreadsheet, the Steps to Matches spreadsheet, and the Y-Utility spreadsheet will be posted on this page of the website. Yellow highlighting on the Sortable Spreadsheet identifies those R1a-Y2619 Ashkenazi Levites whose test results have been added or modified since the last-posted version of the sortable spreadsheet.
