I notice on the Sorenson site (see below) that overall 11 is the value for
DYS 455 in about 81% of haplotypes, while 8 is the value for about 12%. The
numbers in between are very small - almost 0% for 9 and 2% for 10. The
numbers at ybase.org are similar.
Have you and anybody else noticed three-step mutations from 8 to 11, or the
reverse, similar to the three-step mutation we have in 385-b in our Hurst
project? I'm still working on my theory that for some of the segments
multiple-step mutations are fairly normal between specific values.
