UPDATE on my Uncle Russ Allen’s DNA: Thru FTDNA (familytreedna.com)
We have updated his R-Z2542 SNP’s (R1b – L21 SNP Pack) and this is what they have came back with: Your Confirmed Haplogroup is R-Z2542 – Haplogroup R-P312 is the descendant of the major R-P25 (aka R-M343) lineage and is the most common in Central Europe, Spain, France, Portugal, and the British Isles.
You will find all of the Y-Chromosome STR DNA haplotypes posted on the main ALLEN DNA Patrilineage 2 Project page in this haplotype chart, with copious, detailed analysis of the the DNA elsewhere on the page. One of the main points that I make in the “Principles of DNA Analysis” section is that FTDNA’s pairwise haplotype Genetic Distance numbers have only a very weak correlation with closeness of actual relationship and should be disregarded. Like so many statistics thrown at us today, not only by the ignorant media, but by scientists who need better grounding in statistics, pairwise haplotype comparisons, even across 111 markers, represent too small a sample size to yields genetics distances that are statistically significant.
You will find complete, vetted, and up-to-date ancestries of each project member on the project Descendancies page, and clicking on the project number of any member wherever it is a link, will take you to their particular ancestry on the page.
I have put hundreds of hours into building up this page, and in researching or validating the underlying genealogies, and I keep it up to date to the extent that the members keep me up to date on their research. Why not take advantage of it?

Note from Coni: Our project number (which you can find in the project directory) in this project is A-26. This is the main Allen project I am involved in with Uncle Russ’s DNA. John has done so much work for us all and I can’t thank him enough for all he has done & continues to do~
The new FTDNA R1b-L21 SNP Pack is best described as the R1b-L21 Top-Layer and Misc Subclades SNP Pack. You could think of it as a backbone or orientation panel but it is much more of a stocky, short bush than a long backbone. This Pack is the early branching of L21, DF13, DF63, etc. A couple experimental SNPs, i.e. ZZ10, are thrown in. People with haplogroup labels R-L21, R-DF13 and R-Z2542 should definitely consider this.
What is a Single-nucleotide polymorphism via Wikipedia.org
A single-nucleotide polymorphism, often abbreviated to SNP (pronounced snip; plural snips), is a variation in a single nucleotide that occurs at a specific position in the genome, where each variation is present to some appreciable degree within a population (e.g. > 1%).
For example, at a specific base position in the human genome, the base C may appear in most individuals, but in a minority of individuals, the position is occupied by base A. There is a SNP at this specific base position, and the two possible nucleotide variations – C or A – are said to be alleles for this base position.
SNPs underlie differences in our susceptibility to disease; a wide range of human diseases, e.g. sickle-cell anemia, β-thalassemia and cystic fibrosis result from SNPs. The severity of illness and the way our body responds to treatments are also manifestations of genetic variations. For example, a single base mutation in the APOE (apolipoprotein E) gene is associated with a higher risk for Alzheimer’s disease.
