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 -- dr. dan davison/dept. of biochemical and biophysical sciences/univ. of Houston/4800 Calhoun/Houston,TX 77054-5500/davison@uh.edu/DAVISON@UHOU Disclaimer: As always, I speak only for myself, and, usually, only to myself. -- dr. dan davison/dept. of biochemical and biophysical sciences/univ. of Houston/4800 Calhoun/Houston,TX 77054-5500/davison@uh.edu/DAVISON@UHOU "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. [Houston Post, Sun.
