Y-DNA Haplogroup R Naming Nomenclature

Category: Y-DNA » Y-DNA SNP

As research into the R subclades progresses at a rapid pace, the scientific community routinely renames existing subclades to accommodate the rapid growth of the Y-DNA phylogenetic tree. That means that as research progresses, your R subclade will continuously be re-assigned the latest name using the latest naming system.

If the name of your R Subclade changes, it does not mean that your results or SNPs have changed. It simply means that the name of your R Subclade has been updated to keep up with the latest naming nomenclature in this field.

Latest Updates:

Oct 21, 2009: Today, the R Subclade naming nomenclature has been updated according to the latest naming system in the Y-DNA phylogenetic tree. Two new subclades, R1b1b2a1 and R1b1b2a1a1d1a, have been identified and these two subclades can be confirmed by Stand Alone SNP Panels L51 and L47 respectively. All participants in the system will be automatically re-classified using the latest haplogroup or subclade name under the updated naming system. Please refer to the following table to view the old and the new names of the various Subclades of Haplogroup R:
