Y-Haplogroup Projects and Websites

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 continu-
ing, 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.
