What is a SNP:
SNP is short for single nucleotide polymorphism. They 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. When this change occurs (also known as a mutation) the new genetic information is passed down to the next generation. Using these change, which occur about that we can then use to determine how people are related to each. SNP changes occur in the Y-DNA on average every 83 years, although this is a generalization. These mutations allow for the creation of a genetic family tree like the one above. SNPs have different names depending on where they were discovered. (For example a SNP whose name starts with FGC was discovered by the company Full Genome, a SNP that begins with a Y was discovered at YFull, and a SNP discovered by FamilyTreeDNA using the Big Y will start with BY.)
How you can use SNP testing to discover how you fit on this tree:
The Y-700 test (formerly known as The Big Y) is the most helpful test because you can discover your own personal SNPs, and you will have your own branch on the R1b-FGC14628 SNP tree. Big Y looks at 12 million locations on the genome and you will get more than 600 STRs/markers. However, there is another alternative. You can test a custom pack at a private company called YSeq to see if your lineage is in one of the six (of eight) discovered branches under R-FGC14600. If you are interested please contact one of the administrators for details. Unfortunately, there are not yet enough testers upstream of R-FGC14600 to make similar tests at YSeq outside of that subclade.
