By the way Glen, would you believe that Ix splits into two separate
populations before we know what it is and where it belongs? I had tabulated
the Sorenson Ix haplotypes, about 50 of them, and at DYS448 got almost all
19 and 21 repeats in about equal numbers and hardly a 20 in sight. At first
I worried i was picking up a very strange haplogroup from the Amerindians
(many South American hits), but that theory did not hold up. So I went to
Ysearch and sure enough ---there were 12 haplotypes of Ix with 19 at 448 and
12 with 21, but only 3 with 20 and 1 with 18. So Ix is bi-modal at DYS448.
I forgot to check which one your are in.
Now if I can find bimodality at some other markers which correlate with 448,
we have two populations --- Ixa and Ixb. The pedigrees in Sorenson did not
look much different from one to the other which is unusual.
