Correction on the Y chromosome

I got an email from Jeff Tomkins, wherein he pointed out an error in a previous post:

...you got your SNP data backwards regarding the 2001 Nature paper. The SNP rate is much lower (Table 1) - about 4X for the Y-chromosome. The authors use a somewhat confusing "kb per SNP" rate rather than "SNP per kb" rate, don't ask me why.

He's right. My apologies.
