Y-DNA Analysis

This website includes a number of tools for analyzing the relationship among R1a1a Ashkenazi Levites.  (On May 23, 2020, (1) the materials previously posted on the bottom of this page were moved to other pages; and (2) most of the pages that had previously been subpages to this page were moved elsewhere on this website.)

The website posts the following materials of relevance to the Y-DNA analysis of R1a-Y2619 Ashkenazi Levites:


(2) STR marker values for R1a-Y2619 Ashkenazi Levites (including (a) the R1a-Y2619 Ashkenazi Levite Sortable Spreadsheet with STR marker values for R1a-Y2619 Ashkenazi Levites who have done Y-DNA STR testing or Big Y testing, (b) a spreadsheet showing the genetic distance between each R1a-Y2619 Ashkenazi Levite who has done STR testing, and (c) a Steps to Matches spreadsheet designed for use in sorting the Sortable Spreadsheet to analyze an R1a-Y2619 Ashkenazi Levite man's closest matches).

(3) A table that shows: (a) how frequently specific STR marker values mutate, according to Family Tree DNA and a 2010 study by Burgarella, et al.; and (b) the percentage of deviations from the R1a-Y2619 Ashkenazi Levite mode for each STR marker.



The website also posts information concerning the use of tools to analyze Y-DNA results (and, in particular, the R1a-Y2619 Ashkenazi Levite Sortable Spreadsheet and the Steps to Matches spreadsheet).

Finally, the website presents: (1) a piece posted on this website in 2014 with regard to (a) the possibility that SNPs would supplant STRs in Y-DNA analysis and (b) the state of SNP analysis for R1a-Y2619 Ashkenazi Levites as of that time; and (2) Anatole Klyosov's comment with regard to that piece, providing his insight on STR and SNP analyses for R1a-Y2619 Ashkenazi Levites based upon the information available at that time.
