I've been looking for a reference to the use of Muller's ratchet in
the evolution of sex chromosomes, but haven't been able to find either
the original reference or such a discussion.  Anybody out there know?

There is a discussion of Mueller's ratchet and the accumulation of
deleterious mutations in John Maynard Smith's "Evolutionary Genetics"
but he doesn't discuss the specific case I'm interested in.

thanks,
dan

"Mars is essentially in the same orbit...somewhat the same distance
from the sun, which is very important.  We have seen pictures where
there are canals, we believe, and water.  If there is water, that
means there is oxygen.  If oxygen, that means we can breathe" -- Vice
President Dan Quayle, Head of the National Space Council, when
questioned on CNN about why America should send a mission to Mars.
