Re: Mutation Rates for New Markers at FTDNA

The previous post is contains the combined mutation rates from Ballantyne and Burgarella. I used numbers at www.yhrd.ord for DYS385, since Burgarella did not include multi-copy markers. Ballantyne used the number of meiosis instead of allele transmissions for multi-copy markers. I converted them to allele transmissions to be consistent with YHRD. This is simply meiosis X number of alleles.
The frequentist rate is just the usual method of dividing the number of mutations by the number of allele transmissions. I calculated the Bayesian median by dividing the number of mutations plus .69 by the number of alleles. This is the effective difference, although not exact. See this post for an explanation:

The rates for markers 1-67 were calculated by John Chandler and can be found here:

His methodology can be found in this paper:

The rates for the last eleven markers were taken from a poster at SMGF.
