R1b-L21 is the branch of the human family tree marked by the mutation L21+. This includes all R-L21 people. It is the most common Y chromosome subclade of paternal lineages in the British Isles and is also significant in France. It is found across Western and Central Europe as well as Scandinavia. Other names for L21+ are M529+, S145+. Other SNPs that are equivalent to L21+ are L459+, FGC3218+. Recently we've discovered that Z245, Z260 and Z290 are equivalent to each other but slightly older than L21 so Z290+ people are also included. There are almost 3,000 branches and over 6,000 SNPs on FTDNA's R1b-L21 haplotree. The larger subclades are marked by CTS4466+, DF13+, DF21+, DF41+, DF49+, DF63+, FGC5494+, L1335+, L513+, S1026+, S1051+, M222+, Z251+, Z253+, Z255+, Z2542+. If you are positive for any of SNPs listed or any other descendant SNP, you are invited to join the project. Just click on the JOIN button above in the banner and login in with your kit #.
The goals of the R1b-L21 & R1b-Z290 and Subclades project are to gain deeper understanding of the origins and migrations of our male lineages, as R1b-L21 people, while helping you find family paternal lineages and deep ancestral origins. An important role of the project is to support DNA testing steps that will help identify where you fit within R1b-L21. This may lead you to one of the large subclade of L21 projects, which are highly recommended.
Even if you are engaged in other projects and are already deeply tested, please join or to continue in the R1b-L21 & Z290 project, but in the role as a model for others. We need people who have tested deeply to stay in the project and be included in the R1b-L21 Haplotypes comparisons so the new people can learn what testing they might consider and the compare themselves with model haplotype results. Leaders want potential matches to find them and test for their SNPs as documented on the tree. The best models are those with Big Y and 111 STR tests completed. We also need thought and discussion leadership.
An important task is to discover the full deep ancestral family tree of paternal lineages for all R1b-L21 people. This will help us understand the origins of R1b-L21 as a whole, at the subclade levels and down to the genealogical family tree level. The primary method of marking branches in the tree are SNPs so this project is for people who are interested in SNP testing. Please read this web page entirely. Below you will find:
Key Steps to Take1. You must have a Y DNA test result and at least 12 Y STRs with Family Tree DNA (FTDNA.) National Genographic Project testers can easily join, but first you must transfer your test results to FTDNA by following the instructions at your National Genographic web page. Testers will not appear on the project screens and in the Y matching system without the STRs.
2. To join this project click on JOIN in the graphic banner above and login with your FTDNA account ID and password.
3. Update your FTDNA account by going to MANAGE PERSONAL INFORMATION. This is critical to finding potential relatives and understanding origins. We have to share data for the project to be successful. I recommend using the tested person's last name as the Contact Last Name but using the First Name for full name with "c/o" of the kit owner if different that the tested person.

3B. Go to PROJECT PREFERENCES to grant Full or Limited Access for the current project administrators. We can't help you if you have not granted at least Limited Access.
5. If you have not yet tested to 111 Y STRs (Short Tandem Repeats) please upgrade. R1b is young so it is hard to discern between subgroups and potential relatives oftentimes without 67 STRs as a bare minimum. 111 STR testing is clearly preferable and a better deal in terms of cost per STR. To learn more, read http://www.familytreedna.com/learn/y-dna-testing/y-str/upgrading-markers-improve-information/
More STRs can help...
a) identify your signature markers, guiding you on SNP/haplogroup testing and saving money on that kind of testing,
b) provide additional and better matches on your myFTDNA matches screen, even new matches can show up,
c) improve precision for Time to Most Recent Common Ancestor (TMRCA) estimates,
d) and going all the way to 111 Y STRs supports family tree building when you reach brick walls in your genealogy, since the 111 STR panel is estimated to have a change once every three generations.
SNPs can be ordered one at a time from FTDNA by logging into your myFTDNA account, selecting the blue UPGRADES button and then scrolling down to the ADVANCED TESTS box and the BUY NOW button. SNP Packs can also be ordered here.
6A. Big Y is the preferred test. It is probably the most important test you can take. It is a Next Generation Sequencing (NGS) test that discovers new SNPs by scanning over 10 million locations on the Y chromosome. The tremendous benefit in this is you will discover SNPs for just your paternal lineage as well as identify ancient SNPs that you may share with many, many other people. Big Y has the ability to discover SNPs that are pertinent to the genealogical timeframe, the last couple of hundred years. The Big Y learning web site has more details. http://www.familytreedna.com/learn/y-dna-testing/big-y/ Please read the Lewis and Clark Expedition analogy for Big Y exploration on the R1b project FAQ page. http://www.familytreedna.com/groups/r-1b/faq/
6B. The R1b-L21 SNP Pack is a very cost effective option that provides very good coverage of the early branching and smaller subclades of R1b-L21. It can place you in the appropriate major subclades of R1b-L21. You can order it from your myFTDNA account. If you don't see the option, please check the blue UPGRADES button, then the BUY NOW button in the ADVANCED TESTS box, and pick SNP PACK in the SELECT A PRODUCT box. See the R-L21 project FAQ web page for a list of packs and guidance. Please post on the R1b-L21-project yahoo group if you have questions.
If you have a true interest in genetic genealogy and breaking beyond the brickwalls of your genealogical records, please strongly consider both Big Y to determine your haplogroup down to a very recent timeframe and 111 STRs so that you can refine your close-in family and surname mutation history tree.
Project Considerations and Operations
The project administrators are volunteers and do not represent the vendors nor receive special benefits.
This is a public project. The more of us who test and share our information, the more we will all know. When you join you're making surname, ancestor and DNA related results public, from which they can never be fully retracted. Please remove yourself if you don't want to share publicly. We do not publish your full given name or contact info.
This is a Y DNA haplogroup project. Actively participating involves Y SNP testing. SNP testing is required to be assigned to a subgrouping.
The project is designed to support genetic genealogy for hobbyists. It is not intended for forensic or legal purposes. FTDNA policies apply.
Thank you for your consideration. Please review the Results web page. If you have specific questions please post join the R1b-YDNA discussion group at http://groups.yahoo.com/neo/groups/R1b-L21-project/info
More about SNPs
Single-Nucleotide Polymorphisms (SNPs) are critical for R1b people as they are very stable, rarely mutating. R1b is both a very large group and relatively young. Most European R1b paternal lineages are related within the last several thousand years. That means that R1b STR based haplotypes often look alike. The most common pattern of Y STRs is the Western Atlantic Modal Haplotype (WAMH). Most R1b people match several components of it. It is just a remnant of the fact we are closely related. SNPs help differentiate the branches of R1b-L21’s descendants tree. A high level simplified version is on this project's About Overview web page.
R1b-L21 itself, the main branch of our tree, is marked by the SNP L21. We all are L21+ since it was present in our common ancestor, a single prehistoric man. There are now thousands of known branches on the R1b tree.
Many of these branches have coincidentally matching Y STRs. In other words, their branches appear to cross. This gives us false matches.This is definitely a problem with limited haplotypes of 37 or less STRs. 67 is really the bare minimum in most cases and 111 is the new standard. There are now 6,000-10,000 L21 people with 111 STRs in FTDNA's database.
STRs are very useful for general guidance and for matching at the very recent family level, but they are not 100% reliable since some mutate relatively quickly and go both up and down and back to where they started from.
SNPs are much more reliable markers for our paternal lineages. Theoretically, they are permanent throughout eternity so they reliably show our branching of paternal lineages. The number of SNPs available for testing is growing as more and more advanced testing is developed. You will want to identify your terminal SNP, which is the youngest SNP mutation that you have, that is on a formal Y DNA tree. Your terminal SNP tells you where you fit from a deep ancestral perspective.
a) make you more efficient by avoiding false matches when checking for potential genealogical relationships,
b) help you identify deep ancestral family, clan or historical origins,
c) show you what geographic locations might produce additional matches and pertinent genealogical or historical information and
d) benefit all R1b people in general, as well as science, because we'll have a better understanding of how and when this lineage of men spread across Europe as rapidly and as dominantly as it did.
