What you are proposing to do sounds reasonable to me, and I think that Dennis Wright may have attemped something similar recently. I think you could go to Ken Nordtvedt's site and use his Generations 5 program. I wouldn't use modal haplotypes, because then you wouldn't be using the current diversity of the clusters to figure the age. Surely someone who knows more about this than I do could say more.

I've received no response to my note below, which I gather means no one
thinks my idea is a good one. Can someone perhaps explain the folly of my
approach and suggest some other way to investigate the concept?

Thank you.

Subject: [DNA] Comparing Irish Clades

Has anyone compared any of the recognized Irish clades - NWI, South Irish,
Type III, to see how long ago they would have had a common ancestor? ? I
know these three are not the only ones, but they may be the largest.

What would be an appropriate methodology - would you use the modal haplotype
for each or take a selection of members of the clades. Would you compare
each to the other separately or all three together?

I know choice of mutation rates and years per generation and which loci are
chosen will make a difference - perhaps a considerable one - but even the
relativity of age would be interesting. Which is the youngest, I wonder?

Thanks for any advice.

Elizabeth
