Some yDNA specific resources:
For an ever growing, easily navigable, searchable for specific SNPs, tree of all haplogroups – with age estimates of the branches.
If you have tested Next Generation Sequencing such as BigY – do think of adding yet more value to your investment by having the results analyzed at YFull. As more people test and get added the tree is continually refined, as is YOUR terminal SNP with no further effort on your part.
You are contributing to the fascinating and fast growing science and knowledge of mankind.
Alex Williamson’s “The Big Tree“
“This is a draft phylogenetic tree for the R-P312 Y-DNA haplogroup. The data for this tree come from NGS sources including the BigY test at FamilyTreeDNA, the various tests at FullGenomes as well as the 1000 Genomes project. These are discovery tests. They sequence the DNA to reveal novel SNPs and INDELs which mark new branches of the tree. If you wish to be included in this project, you must complete one of these NGS tests.”
My own haplogroup trees (Haplo I, Haplo R), for those yDNA testees of particular interest within assorted surnames projects I administer at FamilyTreeDNA (definitely lag behind the above, there’s only so many hours in a day!)
