Family Tree DNA will be updating its matching thresholds in the very near future (QC is currently being run). Here’s a flowchart of the modified matching algorithm:
From FTDNA’s announcement (modified to indicate that the changes are coming very soon):
You asked for it – we listened!
For several years the genetic genealogy community has asked for adjustments to the matching thresholds in the Family Finder autosomal test.
Currently, the current matching thresholds – the minimum amount of shared DNA required for two people to show as a match are:
– Minimum longest block of at least 7.69 cM for 99% of testers, 5.5 cM for the other one percent
– Minimum 20 total shared centiMorgans
Some people believed those thresholds to be too restrictive, and through the years requested changes that would loosen those restrictions.
