A single I1 full sequence is nice if we get something more. But by itself
it doesn't tell us anything about I1. It does however give a decent
estimate of the average mutation rate across all 27 million nucleotide sites
of the y. And it seems about what people have been assuming; m = 2 / 100
million. This is based on 2460 snps differing from HUGO.

There has been no word yet from the walk the y projects ahead of the I1 in
the Q --- such as I2/I2a2 and I2b1*
