I just wanted to let everyone know that I've updated the DNA 101 section on the blairdna.com (http://blairdna.com/) website. DNA 101 has now become DNA 101, DNA 102, and DNA 103. DNA 101 remains pretty much the same and discusses DNA and the Y-Chromosome as it pertains to genealogy. DNA 102 and DNA 103 come from I presentation I gave at a Guild of One Name Studies DNA Seminar in Cheltenham, UK on February 20, 2010. DNA 102 covers what DNA testing can and cannot do and goes into some detail on interpreting the test results. DNA 103 deals with the methods and rationale I use to group participants in the Blair DNA Project. I hope these prove useful to both individuals and project administrators.
