About us

Project Summary
Annual bulletin goes out late October / early November

Our publicly available haplogroup work is on our external project website at jointprojects.dnagen.org. See Haplogroups.

 

If you are new to Y DNA testing, see part III of our DNA Testing Q & A. Familiarity with STRs, SNPs, SNP streams, and ISOGG long-form order are recommended.

 

Here at FTDNA, project testers can log in and see Y results clusters inside the project and read the annual project bulletin, published around the end of October / early November to coincide with the year-end DNA test sale.

To see project yDNA results:

1. Log in to your FTDNA account. You should see your dashboard.

2. From myProjects (left sidebar) click on the project name.

3. Click DNA Results (left sidebar).

4. To better see the contrasts in results, click Y-DNA Colorized Chart.

 

Clusters labeled UNMATCHED, LINEAGE, PEDIGREE, and INSUFFICIENT DATA

There are multiple numbered clusters in the Y results. They are categorized as UNMATCHED, LINEAGE, PEDIGREE, and INSUFFICIENT DATA according to how well members match on their STRs and how much testing has been done.

INSUFFICIENT DATA means that insufficient testing has been done to know with reasonable confidence whether testers are related. 12 or 25 markers are usually not sufficient, unless you have a well-documented paper trail showing your relationship to other members of the project.

UNMATCHED members mean they have no project-relevant surname matches within a significant number of markers tested. For detailed explanations of why this occurs, see part III of the DNA tutorial.

PEDIGREE members are grouped with other members sharing the same documented common ancestor and are genetically very close, showing small or no Genetic Distances between them.

LINEAGE members are genetically related, as evidenced by the similarity of their markers and also by sharing certain mutations. They may not be as genetically close as pedigree members. Or they may be very close but lack the documentation to push their research back to a named common ancestor. A LINEAGE could have a PEDIGREE embedded within it.

Many members do not document their earliest known paternal ancestors. Close matches are assumed to be LINEAGE unless their earliest known paternal ancestors are documented and appear to be the same person.

SNP Testing

The column immediately preceding the column starting the STR markers shows the testers terminal SNP.

Cluster Labels

Cluster order is by parent haplogroup, and by ISOGG long form order of SNP subclades. The long forms themselves are not shown.

Your cluster label has a number, then a description of a parent haplogroup. The label shows a stream of SNPs separated by ">".

The leading numbers are sequenced to reflect ISOGG long form order.

Next follows an SNP stream, with the SNPs separated by ">". This is a flattened representation of what is in FTDNA's Y-DNA haplotree. Because of space limitations, not all SNPs you see in your SNP stream in the haplotree will necessarily be in your cluster label.

Without further information, we may try to estimate your terminal SNP by looking at your matches (whether with your surname or not) at 67 markers or better. Sometimes terminal SNPs conflict. In such cases, we'll try to label your group using a parent SNP that we think contains the conflicting child SNPs.

The labels are also designed to be readable vertically. Scan your eye up and down the page and you should see the same parent SNP stacked in a column.
