David,

Thanks for your deep knowledge of the science of all this. One thing I'd
like to understand better--and this may be related to what you just
stressed--is that any 67 marker match implies a closer match than any 37
marker match. So, a person who matches at 67 -4 is more likely to be related
to my father than an exact 37 marker match. I have called FamilyTree DNA on
this and they confirmed. I also suggested that they list the 67 marker
matches on top because these are what I believe most people are most
interested in. Any based on their science, an exact 67 match implies a very
close generational match, so that person could have strong physical
similarities worth pursuing.

Thoughts?

Marie

This was already addressed, but I wanted to reinforce the point more
generally.

Markers 38-67 are slow-moving markers, so for a given population the
variance will be less compared to the first 37 markers. It's not just
R1b1c7. In any haplogroup with a relatively compact distribution, two
individuals are likelier to lie closer to one another on the last 30 markers
than in the first 37.

The long silence was getting a bit to loud .Hey R1B1C7's if you want to
have some fun ? Create a new Y-search user by only plugging in the last 32
Markers of your 67 marker test .Set the limit to a genetic distance of 2
or 3.for comparing To bad but not all R1B1C7's use Y-search. Or simply
eyeball the R1B1C7. Haplogroup they appear to be closer in genetic distance
than other haplogroups when comparing only the last 32 markers, for some
reason.How strange is that?
G Ashley.
