R-P312 and Subclades Project (to view all results, set Page Size to 1200)- Background

Background

P312 is a Single Nucleotide Polymorphism that characterizes a major R1 haplogroup. There are a number of haplogroups and subclades downstream of P312 (see the YCC phylogenetic tree on your "myFTDNA" pages "Haplotree" page).

What is an SNP or Single Nucleotide Polymorphism? An "SNP" - Single Nucleotide Polymorphism - represents a change at a single nucleotide (A=adenine, C=cytosine, G=guanine, T=thymine) on the y chromosome. In the case of P312, that change occurred at the position known as rs34276300, where we have an "A" instead of the "C" most everyone else has. You can trace our shared ancestry by using the YCC phylogenetic tree on your "myFTDNA" pages "Haplotree" page.

The ancestry of all P312+ men, in terms of SNPs, runs like this: M207+ . . . M173+ . . . M343+ . . . P25+ . . . P297+ . . . M269+ . . . L23+ . . . L51+ . . . P310+ . . . P312+

Purpose The purpose of this project is to explore the distribution of P312+, characterize the relationships between its subclades, conduct researches into the age and history of the clade, and to make available a large database of P312+ haplotypes to researchers, both professional and amateur.

Joining the R-P312 and Subclades Project: One must have a P312+ result from Family Tree DNA. If you tested P312+ (S116+, rs34276300=A) with some other company, please let us know by email. To join, click on "Join Request" at the top of this page.
