An earlier post today involved new information acquired from Y-chromosome testing using the results of Family Tree DNA's Big Y-700 test. The test is relatively new having been rolled out only about a year ago. We're just starting to see results from tests and the more tests we have the more we'll get to see just how useful the testing is. Rather than try and explain the ins and outs of this new test myself, I thought that I would simply provide some links to other sites online that would provide the interested reader with more information.
We'll start with Family Tree DNA's own white paper on the Big Y-700 test, and the company's Big Y page at their Learning Center.

The last link above suggests some options and provides instructions on uploading your date to the "Big Tree" which is specific to those in the haplogroup R-P312. To date, and to my knowledge, no member of the Brewer DNA Project has yet to be identified with this SNP. Members of the Brewer DNA Project who do order the Big Y-700 should consult Hank Graham, the Project's administrator, for instructions on how to proceed once their Big Y-700 test results are reported. You may also find instruction if you scroll through the Project's Activity Feed page (available to project members only). The Brewer DNA Project uses YFull for further analysis and placement on their YTree. Again, those considering joining the Project, or considering an upgrade to the Big Y-700, should contact the administrators of the Brewer DNA Project with any questions.
As of this post, the Brewer DNA Project has 370 members spread across ten sub-groups (and a set of ungrouped members), of which 112 members have taken one or another version of the Big Y test (at least 65 have taken the Big Y-700).
