My data is derived from the Zhiv evolutionary average. The 388 is 3X slower because I only use R1b for mys set of mutation rates.McGhttps://www.blogger.com/profile/03459589185170647441noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-89933849062359423192008-11-01T12:31:00.000+02:002008-11-01T12:31:00.000+02:00This article added to the subsequent one are very ...This article added to the subsequent one are very interesting. I am an advocate of Zhivs rates, as you know. I also believe germline rates and Zhivs rates should be the same. So whats the problem. The problem is that Chandlers rates are contaminated. I would argue that the equivalence only makes sense for the same HG!! If germline rates are estimated from one one haplogroup they are very close to the evolutionary. Look carefully at Chambers data for 426 and 388. From Zhiv and using 30 year per gen I get the same number for Zhiv and germline(chambers). This if possibly fortuitous but 426's rate for I1a and R1b is the same. However, depending on if you count using ASD or simple, 388 is 3X to 10X faster for I1a (3X to 10X the number of mutations)compared to R1b. Chambers used a mixed set of HG's, without paying attention to STR mutation rate variability across HG) and it is reflected in his results. Note the overall average mutation rate is the same for the two HG's. It is just that several different STR's differ from group to group and will give false estimates if they are used.<BR/><BR/>In conclusion, I think the second paper has it right - they give the same answer if the dys loci you use have the same rate across HG's, or if you stay within a haplogroup.McGhttps://www.blogger.com/profile/03459589185170647441noreply@blogger.com
