Encyclopedia of Y-DNA Origins

Y-DNA Haplogroup Tree Origins


The Encyclopedia of Y-DNA Origins is a guide to what is known about each Y-DNA branch. Today, much of what we know is raw material from personal DNA testing, Geno 2.0 results, research samples, and published papers. This is built around the structure of the Y-DNA Haplotree at FTDNA. The encyclopedia brings the data from those sources together in a format that allows new knowledge of our maternal origins to emerge.
