Y-DNA Haplogroups

This is a master project, to collect information about the specific yDNA haplogroup projects on Geni.

All modern humans descend in the male line from a particular man, nicknamed “Genetic Adam,” who lived in Africa about 60 to 90 thousand years ago (~3,000 to ~4,500 generations). All living men have inherited his y chromosome (yDNA), along with the mutations that have accumulated in our individual family lines.

Unlike autosomnal DNA, yDNA does not recombine. It passes intact from a man to his sons. (Women do not have y chromosomes.) And, the mutation rate for yDNA is very low, perhaps one mutation at a given spot every 14,000 years. Therefore, a family’s yDNA changes very slowly over many generations. Every man whose y chromosome contains a particular mutation shares a common paternal ancestry extending back thousands of years with every other man who has the same mutation.

These characteristics make yDNA useful to both geneticists and genealogists. It is a useful tool for understanding the remote origins of the human race, for tracing pre-historic population movements, and for matching people who belong to the same male line.

How to Participate

Geni Wiki Projects Page

To participate in this project, join or follow any of the haplogroup projects, then add your oldest known ancestor who belonged to that haplogroup.

If your ancestor belonged to a group that doesn't have a project, send a message to one of this project's collaborators. We'll create a project for you.
