Drawing the human Y chromosome tree with SNPs

Terry, (, a poster at GENEALOGY-DNA-L reported age estimates for various nodes of the Y-chromosome tree based on SNPs. These can be found in this PDF file and here (scroll down for UPDATE10). He used 1000 Genomes data and SNP counting to reach these estimates. It will be nice to see others join in on the SNP bandwagon, because that is really the way forward in age estimation for Y-chromosome lineages.

Age estimation of Y chromosome lineages (Adamov & Karzhavin 2010)

Academics / Anthropology : Dienekes' Anthropology Blog (4 years ago)

A nice paper in the Russian Journal of Genetic Genealogy that addresses the subject of age estimation using Y-STRs. The authors share my sentiments on the subject, and were good enough to compare their simulation results and analyti... Read Post

Human Y chromosome much older than previously thought

Academics / General Science : Science Codex (last year)

UA geneticists have discovered the oldest known genetic branch of the human Y chromosome – the hereditary factor determining male sex. The new divergent lineage, which was found in an individual who submitted his DNA to Family Tree ... Read Post

Estimating the age of Y chromosome Adam

Academics / Anthropology : Dienekes' Anthropology Blog (2 years ago)

I took chrY SNP data from the 1000Genomes Project, with the goal of estimating the age of the root of the Y chromosome phylogeny. I used the mutation rate of 3x10^-8 mutations/nucleotide/generation of Xue et al. (2009), and a genera... Read Post
