The first phylogenetic chart to unify nomenclature was
published in 2002 by the
Y Chromosome Consortium (YCC). The 2003 Y-DNA phylogenetic chart
appeared in Mark A. Jobling and Chris Tyler-Smith,
The Human Y Chromosome: An Evolutionary Marker Comes of Age Nature Reviews|Genetics, Figure 5.
In 2005 Family Tree DNA created the
2005 Y-Chromosome Phylogenetic Tree. An ISOGG group was formed in November 2005 to create a web-based document
using Richard Kenyon's style of an indented list which could be
updated to keep pace with the rapid developments in the field.
Current ISOGG members who work with the tree are: Coordinator: Katherine Borges. Content editors: Ray Banks, Owen Lu. Content persons liaison with experts from various reliable sources to determine what information is needed to amend the tree.
The Y Haplogroup classification of the male Y-chromosome is currently used to estimate the population group of the paternal line. The haplogroups are identified by the letters, A through T. Haplogroups are subdivided into one or more levels, called subclades, and thus forming a tree. The Y-chromosome haplogroup is determined by performing a sequence of SNP tests.
Each line lists a haplogroup or subclade in boldface, then one or more SNPs follow on the same line. For a sample to belong to a particular subclade, it must test positive for any one of the SNPs appearing on the line, providing positive results were obtained for its haplogroup and any intervening subclades.
