YSNPs, Packs and Trees

Resurgence of the FTDNA yHaplotree SNP Packs - A status update

Page 2: YSNPs, Packs and Trees

Haplotree today

May 2015 – 6,556 SNPs Today – 23,767 SNPs Unique haplogroup labels – 6,728 Total “terminal nodes” – 3,192

Page 3: YSNPs, Packs and Trees

Haplotree update guidelines 1. SNP Name*, position (hg19),

mutation 2. Proposed phylogeny/SNP

positioning 3. Provide kit proofs 4. Avoid heavily recurrent, STR

embedded, and other unreliable SNPs.

5. Must be FTDNA generated data 6. No private SNPs (2+ required)

SNP Packs – An Overview Carefully designed

panel of SNPs relevant and encompassing to a specific group (M343, L21 etc.)

Cost efficient method to move a tester down the tree

Can match – Can NOT discover*

SNP Packs

77 active panels (~35 in design)

8 haplogroups (E, G, I, J, N, Q, R, T)

SNP pack process

Admins submit panel proposal (140 max)

Computational QC (Dr. Nossa) Phylogenetic analysis, tree building Validation Content finalization Release

Questions?

I have a BigY, do I need a SNP Pack? Can I buy just one SNP?
