About us

The R1b-BY168 Project is a Y chromosome DNA project designed to collect data on and conduct research into the origins of the SNP BY168, also known as Z18023, recently discovered downstream of FGC5572, and the SNPs downstream of it. Here is the haplogroup R phylogenetic tree of BY168:

R-M207>R1-M173>R1b-M343>L754>L389>P297>M269>L23>L51>P310>L151>P312>Z290>L21>S552>DF13>
Z39589>DF41>FGC5572>BY168.

Hey! Do you have a Y-DNA test result at 23andMe of R-Z18021? Well, that's the same thing as R1b-BY166 (one step downstream of BY168). PLEASE get your Y-DNA tested by Family Tree DNA and join this project! We need you, and you need us, if you really want to learn about your Y-DNA line.

This is a Y-DNA project. Only men have a Y chromosome, which is passed from father to son. Women may participate by having a male BY168+ relative join.

Within the R1b-BY168 subclade is found the Short Tandem Repeat haplotype cluster 41-1123, which is characterized by the following marker values: 390=23; 385=11-11; 447<=24; 464b=16; 534<=14; 413a<=22. The following values are also usually found in the cluster but not always: 458=16 and 439<=11Its members are derived (positive) for the SNP BY166 (also known as Z18021) downstream of BY168.

Not every man who is positive for BY168 is a member of the 41-1123 haplotype cluster, but every member of that cluster is positive for both BY168 and BY166 (Z18021). 
 

Single Nucleotide Polymorphism (SNP) Testing

What is a Single Nucleotide Polymorphism?

The following definition comes from the National Institutes of Health's Genetics Home Reference web site: 

What are single nucleotide polymorphisms (SNPs)?

Single nucleotide polymorphisms, frequently called SNPs (pronounced “snips”), are the most common type of genetic variation among people. Each SNP represents a difference in a single DNA building block, called a nucleotide. For example, a SNP may replace the nucleotide cytosine (C) with the nucleotide thymine (T) in a certain stretch of DNA.

SNPs occur normally throughout a person’s DNA. They occur once in every 300 nucleotides on average, which means there are roughly 10 million SNPs in the human genome . . .

We strongly recommend you order Family Tree DNA's Big Y-700 test or, at the very least, its R1b-DF41 SNP Pack.

To order the Big Y-700, go to your myFTDNA pages and click on "Upgrade" in the upper right of the screen. There you will see the ad for the Big Y test. Click on the blue button to the right of it to order the Big Y.

To order the R1b-DF41 SNP pack, follow the instructions below.

1. Go to your myFTDNA pages and click on "Upgrade" in the upper right of the screen.

2. Scroll down and click on the blue "Buy Now" button under "Advanced Tests".

3. In the "Test Type" box, choose "SNP Pack" from the drop down menu.

4. Scroll down, find the R1b-DF41 SNP Pack, and click "Add".

5. Complete the fields to make the purchase.

Thanks!


Who can join?

If you are a Family Tree DNA customer and have tested positive for the SNP BY168 or any of its downstream SNP's, you are eligible to join the R1b-BY168 and Subclades Project. Likewise, if you are a Family Tree DNA customer and belong to the 41-1123 haplotype cluster (explained above), you are eligible to join this project.

If you can join the R1b-BY168 and Subclades Project, you should also join the R-DF41 and Subclades Project and the R L21 and Subclades Project at the following links:
