Haplogroups are the groupings of mankind based on analysis of the y-chromosome,
which has been passed from father to son since the beginning. Each haplogroup represents a branch of the "Family Tree of Man". Haplogroups were assigned letters
of the alphabet before the complete analysis was done which means that the specific letter assignment itself is meaningless. However, our learning over time has allowed
us to correlate each haplogroup to man's migration as we populated the earth. This learning, which is continuing, makes the Haplogroup designation very interesting - as
it identifies which migration path our ancient ancestors took.
A man's Haplogroup is typically estimated, based on the markers evaluated in his yDNA test. To be certain of the Haplogroup, a formal test, often called a SNP (pronounced
"snip") test must be done.
There is a large and ever-growing body of literature on Haplogroups. General Haplogroup
resource information is found at the bottom of this page. This table provides links to the
Y-Haplogroup projects at FTDNA and to information specific to Y-Haplogroups.
