ISOGG List of Haplogroup projects at FTDNA
Origins, age, spread and ethnic association of European haplogroups and subclades - Eupedia
Y-DNA Haplogroup I and its Subclades - 2010 (International Society of Genetic Genealogy -- ISOGG)
Y-DNA Haplogroup R and its Subclades - 2010 (International Society of Genetic Genealogy -- ISOGG)
Y-Haplogroup I1 STR "Cluster" Analysis - “With data based on a large sample of I1 y-Haplogroup people tested at FTDNA (see http://www.familytreedna.com/public/yDNA_I1/), and also using some other data, I have done a mathematical "cluster analysis" to determine any clusters within the I1 y-Haplogroup based solely on STR marker values. The clusters that are found are then linked to the geographic origin of the most distant male-line ancestor reported by each cluster member.”
FTDNA's “Haplogroups and SNPs" - A good textual background on understanding haplogroups and SNPs, though some criticize FTDNA for being too slow to update their tree by basing it on the ad hoc Y Chromosome Consortium group's tree. The ISOGG's tree is widely considered the most current.
