Michael:

Have you seen the various studies of father - son pairs. Fascinating to realize that in one transmission the difference between a father and son could be such that they only match 10 / 12. You can check the articles and download directly from the FTDNA site or www.historicalgenetics.com but it apears that up mutations are about twice as likely as down mutations.

Are mutations within a family always random, or is there directionality? Say
there are 2 or more mutations (off by 1) in known, but distant, relatives
are the mutations always (ever) all plus 1 or minus 1, or just a mixture?
Has anyone checked their family DNA results to conclude anything?
