Several trees that I have seen, produced by different softwares, show R1b
and I1a as rather fragmented bushy bushes (shrubs), while the other clades
and varieties of haplogroup I, for example, very cleanly separate from each
other. It's like night and day.


This is evident in haplogroup I by just looking at the GDs between the
clades and varieties of haplogroup I, and then doing the same for just I1a
and its varieties, for example; drawing a tree is unnecessary. You best do
this with the half of the markers with the slowest mutation rates. The fast
markers contribute lots of noise. Some trees I have seen suppress the fast
markers by various weighting tricks. Ken
