Founded in 2005, ISOGG was the first society for DNA testers

Initially ISOGG focused on Y and mitochondrial tests and thus Family Tree DNA and its projects

Lets  look at the Y SNP tree page next

The Yahoo forum is gone, replaced by other social media such as FaceBook

The Y SNP tree menu item will bring you here

Each umbrella  haplogroup has its own page

Here is part of the R page

Starting in 2018 these are in spreadsheets in google docs

The 2017 tree is easier to read but the nominclature is older

Also there are project leaders for the different subclades listed at the top of the page

You can click on a topic from the homepage to see a list of those articles in the WIKI

On the home page under the list of Genetic Genealogy Resources is a link to a page with the History of this field up to 2008

On both the WIKI home page and the DNA testing page there is a list of Genetic Genealogy Resources

The DNA testing page has a lot of information, both an overview and a list of articles

The DNA testing page includes a substantial list of DNA tests

Many pages in the WIKI could use updating but it is still an amazing repository of information

One page that is kept up-to-date is the Autosomal testing comparison chart by Tim Janzen

Personally, when I want to look up something genetic I ask google and include the ISOGG wiki

Table from Cousin Statistics page:

Observed table of cousin statistics:

If you are on Facebook, join the ISOGG facebook group, they are also on X and Mastodon
