Markers on the non-recombining portion of the human Y chromosome continue to have applications in many fields including evolutionary biology, forensics, medical genetics, and genealogical reconstruction. In 2002, the Y Chromosome Consortium published a single parsimony tree showing the relationships among 153 haplogroups based on 243 binary markers and devised a standardized nomenclature system to name lineages nested within this tree. Here we present an extensively revised Y chromosome tree containing 311 distinct haplogroups, including two new major haplogroups (S and T), and incorporating approximately 600 binary markers. We describe major changes in the topology of the parsimony tree and provide names for new and rearranged lineages within the tree following the rules presented by the Y Chromosome Consortium in 2002. Several changes in the tree topology have important implications for studies of human ancestry. We also present demography-independent age estimates for 11 of the major clades in the new Y chromosome tree.

In 2002, the Y Chromosome Consortium published a single most parsimonious phylogeny of 153 binary haplogroups based on markers genotyped in a globally representative set of samples (Y Chromosome Consortium 2002). A simple set of rules was developed to unambiguously label the different clades nested within this tree. This hierarchical nomenclature system, which has been widely accepted by the research community, unified all past nomenclatures and allowed the inclusion of additional mutations and haplogroups yet to be discovered. Subsequently, Jobling and Tyler-Smith (2003) published a modified version of the Y Chromosome Consortium (YCC) tree; however, since 2003, there has been no unified effort to update the Y chromosome binary haplogroup tree with the hundreds of polymorphisms that have been discovered and surveyed in global human populations. Here, we attempt to bring the Y chromosome tree up to date and present a modified nomenclature based on the rules put forward by the Y Chromosome Consortium in 2002.

The original YCC tree was constructed on the basis of 243 unique polymorphisms, representing most of the binary markers known at the time. Since then, more than 400 binary polymorphisms have been discovered. While this has led to increased phylogeographic resolution for many Y chromosome studies, without occasional unified efforts to incorporate these markers into a fully resolved Y chromosome tree, there is once again the possibility that multifarious and erroneous naming systems will appear in the literature. As we show, many of the newly discovered polymorphisms require topological changes to the tree, as well as new nomenclature to define the lineages. As pointed out by the Y Chromosome Consortium (2002), newly discovered mutations may have the effect of splitting clades or joining previously separated clades, while new samples may contain intermediate haplogroups. The overall goals of this study are to produce an updated tree showing the evolutionary relationships among lineages marked by newly discovered and published Y chromosome markers, to name these lineages, to make mutation information available to the Y chromosome research community, and to date 11 of the major clades in this tree.

This section is for F mt-haplogroup only, not for Y ones :)

I am the only one carrier of F mt-haplogroup at this forum :)

Complete absence of mtF carriers was a little bit amazing for me. But now we have Yfull's MtTree with couple F2f2 guys :)

I am F too

I know somebody who is mtdna F1a'c (assigned that from 23andMe)- their roots are Hainan island, China. I wonder what group(s) brought that subclade to there.

After several updates I was moved on F2f1 subgroup:
