Hi folks,
?
Actually, getting reliable mutation rates for the extended set of Y-STRs would be very valuable and could help us improve the TMRCA estimates by using a marker-by-marker mutation rate instead of the global one currently used. Here's how to do it:
?
(1) One of the admins needs to go into hundreds of accounts in the project and download their Y-STR CSV files.
(2) The CSV files then need to be labelled with their haplogroup.
(3) Pairs of CSV files can then be sampled (sequentially or at random), and the TMRCA of their two haplogroups looked up from Discover (preferably in an automated fashion).
(4) On a per-marker basis, plotting the genetic distance versus TMRCA and fitting it with an exponential function will give us the mutation rate of each Y-STR.
?
Unfortunately, it needs to be done this way because FTDNA haven't given admins a tool to query all 852 Y-STRs on a project-level basis, as they have for the first 111. I haven't had time to do this myself, because I haven't had time to do (1) and haven't had a chance to work out how to automate (3), but if anyone wants to take this one, it would be very helpful.
?
Cheers,
