Ballantyne et al. provide mutation estimates with about 1700 meioses. That's pretty good.I disagree.For starters, Janzen in 20009 didn't have access to Ballantyne's rates (his study is, indeed, a good one) but rather relied on older less well-designed studies.Moreover, the slowest 10 markers used by FTDNA (and, ergo, Janzen) are estimated to average just one mutation for every 8500 meiotic transfers (the 10 slowest have an average rate of less than 0.00012). Even the Ballantyne study was probably an order of magnitude too small to accurately measure those rates.VV |
