SNP Assurance Program (Backbone SNP Test)

Here at FamilyTreeDNA (FTDNA), we want to provide our customers with the highest level of Y-DNA haplogroup confidence, so we created our SNP Assurance Program (which began with test batch 173). With the SNP Assurance […]

A member of my project tested before you implemented the SNP Assurance Program. Will you confirm his haplogroup?

If your project member tested before we started the SNP Assurance Program and their haplogroup is unpredicted on the Y-DNA, Haplotree & SNPs page of their myFTDNA account, we will run the Backbone SNP test for them. Please […]

Will Family Finder Project members be able to see their analytic data? Will they rely on me for all interpretation?

Part of your responsibility as a project administrator is to interpret the genetic relationships between project members in light of traditional genealogical records. Members of your Family Finder Project will see their own matching results. […]

For Family Finder, there is nothing that automatically becomes public like Y-Chromosome DNA results. How can I share related discoveries with my project members?

The Family Finder test provides sensitive information about relationships. Therefore, thought must go into presenting matching results to all project members and to the general public. Before sharing, contact the relevant project members. Please be […]

How can I use the Family Finder test for my surname or paternal lineage group project?

The Family Finder test has many uses within a surname or paternal lineage project. It helps to, Bring into your project men and women who are related but lack a male cousin with the corresponding […]

Why don’t my project members (who are Y-DNA67 perfect matches) match each other with Family Finder?

It is not unusual for the relationship to be undetected. Most Y-DNA67 exact matches are related within six generations. That is 4th cousins. Family Finder test will detect a relationship between only about half of […]

Should I suggest that my group members take the Family Finder test? How do I know when to recommend Family Finder testing?

The best way for you to know what tests to suggest to project members is to talk with them. Often, this happens when someone first tests. If it has been more than two years since […]

What tools are available for group project administrators to analyze Family Finder results?

In GAP 2.0, there are two genetic report pages to help project administrators analyze matches within their project, Family Finder (FF) Illumina OmniExpress Matrix and Family Finder (FF) Illumina OmniExpress Results.

What are ways that I can reach out to potential participants in my Family Finder project?

There are many ways that you can reach out to your cousins to invite them to participate in your Family Finder project. Here are some that may work for you: Call your closer relatives, such […]

When recruiting for a Family Finder project, how closely related should any two participants be?

When you are recruiting for a Family Finder project, it is important to test as many cousins as possible from different descendant lines. Ideally, for any line the participants will be between 1st and 2nd cousins.

May any cousin join my Family Finder project? Does it matter if they are male or female?

Any cousin or suspected cousin who traces their ancestry to the project’s ancestral couple may join your Family Finder project. It does not make a difference if they are male or female.

When planning a Family Finder Project, why is the number of generations back to my ancestor important?

With each generation, the amount of shared DNA and the likelihood of matching between cousins decreases. You need to choose a common ancestor where many project members will have matches within the project.

What is the FTDNATiP Calculator? How do I use it?

FTDNATiP is a program that calculates Time to the Most Recent Common Ancestor (TMRCA). It uses STR marker mutation rates for more accurate calculations.

Why are some haplogroups in red and others in green on the Y-DNA results chart?

Haplogroups that are in red are predicted. Haplogroups displayed in green are confirmed by testing.

What are my options for viewing Y-DNA Results?

In the GAP (group administrator page), you have three options for viewing Y-Chromosome DNA (Y-DNA) results. They are the Y-DNA Classic Results chart, the Y-DNA Colorized Results chart, and the Y-DNA Results chart.
