Many y-DNA haplogroups now have projects at Geni.com, a collaborative website for building family trees. More DNA projects are being added as information becomes available.
Geni.com is a genealogy website, something on the order of Ancestry.com or Rootsweb.com — except that users share management of their common ancestors, and cooperate in the process of researching, documenting and building out their trees. The site currently has over 100 million profiles. It uses a Wikipedia-style environment for research and collaboration. The site’s goal is “to build the definitive online family tree”.
Projects at Geni.com allow users to group the individual profiles of their ancestors into working collections. Projects can be created for a surname, an event, or a topic — anything that connects a number of profiles together.
The DNA projects at Geni.com are expected to increase the visibility of genetic genealogy, and demonstrate the value of genetic testing.
