   Haplogroup Shading Code: Note: all Haplogroup values are reported based on latest Y-DNA Haplogroup Standard nomenclature.
   We update these results as the Standard is changed (usually every 1-2 years).
  R1b1    Predicted - Haplogroup value is predicted by FTDNA based on marker values.
  R1b1    Backbone Test - Haplogroup value is derived based on a now obsolete SNP Backbone Test by FTDNA. Additional SNPs need to be analysed.
  R1b1    Earlier Standard - Haplogroup value is measured based on a Deep Clade Test performed by FTDNA based on earlier
   Y-DNA Haplogroup Standard. Additional new SNPs need to be analysed.
  R1b1    Current Standard - Haplogroup Value is measured based on a Deep Clade Test performed by FTDNA to latest Y-DNA Haplogroup Standard.
 
   Allele Shading Code: Codes to show exceptions to family highlighting based on differences between your results and Predicted Ancestral Haplotype.
   Please note that some alleles have been designated as Fast Mutators - this means that changes in their values MAY have less genealogical significance.
  29    Difference noted for fast mutating allele. Differences may have less genealogical significance.
  29    Difference noted for slow mutating allele.
       No value for this allele was observed. Normally used with for 464e, 464f, and 464g.
       Ordered. Data has been ordered and awaiting report from FTDNA.

Fast vs. Slow Mutating Alleles: The Alleles whose names are in red in the header row have been designated by FamilyTreeDNA as fast mutating. This means that, when comparing two kits, these alleles have less genealogical significance and figure less in determining if two kits have a family match.
