Y-chromosome Test Extended to 111 Markers.

FTDNA just announced to project administrators its long rumored expansion from 67 markers to 111 markers for its most complete Y-chromosome test. In the release the company said:

We are excited to announce the launch of our new Y-DNA111 test!

This test includes a panel of 111 Y chromosome Short Tandem Repeat (STR) markers.* With 44 additional markers, Y-DNA111 is the highest resolution Y-DNA test offered by any company in the world.
The Y-DNA111 test is recommended for customers who already have close matches at the 67 marker level and are looking to tighten the calculation for the time to Most Recent Common Ancestor (tMRCA).** Due to the specialized nature of this test and in order to evaluate the potential benefit of this type of upgrade, we ask that customers with Y-DNA12, 25, or 37 results upgrade to 67 markers first before considering the 111 marker test.
With that in mind, this new test is now available as an upgrade for customers with existing Y-DNA67 results and also as a standalone test for individuals looking to prove a close relationship on the direct paternal line:
Y Refine 67 to 111 (Upgrade)

This expanded test may be of value to those who are trying to differentiate closely bundled lines in surname projects and also to those trying to discover if non-surname matches will continue if more markers are examined.
