Thankyou Mark and Ann,
I don't know how your post slipped past my vulturous eyes except that it was near
Valentine's Day and my one track brain was derailed, Ann. It will be fun trying
to figure it out. I hope Mark and Patrick really get into a discussion on it. I'm
surprised that google didn't find the site you mentioned when I queried for Y
Chromosome Consortium but rather got something dating back to 1994.
