Hello David

I was talking about gd's between haplotypes rather than modals, but I think
you're right - an analysis would be useful. I have a database of some 450
M222 67 marker haplotypes so I'll give it a go.

My guess is that you are spot on at the starting point (very small
percentage at low genetic distance), I don't think your suggested mean of 10
is far off (I think it may be a little higher) but I think you may be
surprised at the frequency of 15+. I'll post the results once I have them.

Sandy

Sandy Paterson says, "Now consider the range of gd's between pairs of 67
marker M222 haplotypes. They range from zero to 29 (possibly higher, but 29
is the highest I've seen), with plenty of them larger than 20."
