How are people estimating TMRCA from BigY results? Yes, I know it's fraught with uncertainty and maybe useless, but I'm just curious.
So what is the process for looking at the total number of tested SNPs, novel SNPs and SNPs shared with matches to come up with an estimated GD and TMRCA?
Is anyone using Doug McDonald's updated TMRCA calculator for this purpose? If so, what are the input parameters you are using; I couldn't figure out what to enter. Calculator is here: http://dna-project.clan-donald-usa.org/tmrca.htm
Related question: When filtering BigY matches by terminal SNP, am I correct in assuming that those who have not tested to my terminal SNP on the FTDNA haplotree would appear in an upstream subclade? I ask because my FTDNA terminal SNP is not tested in BigY and I am trying to sort through my matches to determine which might be worth investigating.
Thanks,
Jim
