This tool is solely intended to assist you in finding matches. The same privacy obligations of the source apply to the personal or DNA information processed and displayed here.
This script allows you to find STR matches within public YSEQ projects and STRs from other sources entered in a tabular format.

Developed by Hunter Provyn in cooperation with YSEQ (Thomas Krahn and Yahya Alalie).

3. Haplotype Matching [Beta]

Haplotypes initially computed by YFull and modified as necessary by Hunter Provyn
Root haplotypes supported: A1a,A1b1,B,C,D,E,G,H,I1,I2,J1,J2a-M410,J2b-M102,L,M,N,O,Q,R1a,R1b-M269,R1b-PH155,R1b-V1636,R1b-V2219,R1b-Y13200,R2,S,T
This feature is still under development and does not yet take palindromic markers into account.
Warning: Querying on a smaller set of STRs decreases the probability of a correct root haplogroup determination, unless a researcher has commissioned me to add a related subclade.

4. Matches

Matches are ranked according to the log sum of their deviating mutations, weighted by each STR's mutation rate (thanks David Vance for mutation rates).
Since May 2024 it uses allele-specific mutation rates that I computed from YFull's computed haplotypes.
For matching alleles, a color code shows the in-project rarity for the shared value.
