Subject: [yDNAhgI] Dr. Krahn's "Walk On The Y" 2007 Presentation
Date: Mon, 13 Apr 2009 00:55:12 +0000
Dr. Krahn gave a much more detailed and informative presentation at the 2007 FTDNA conference, which may be of interest to people. He discussed the problems and differences of Y chromosome testing compared with mitochondrial DNA. It is much longer (24 pages) than the 2009 file (7 pages) and goes through the process of how FTDNA works.
