Uh, could you enlighten me as to why Z/W systems need dosage compensation
-- I thought the Z/W meant that the two chromosomes contained the
same genes except for the sex-determination factor.

You might also look into work on C.elegans and speculations as
to the evolution of dosage compensation and hermaphrodism there.
I believe Jonathon Hodgkin is a major author in the field.

(a really fuzzy thought -- I think I saw some speculation on
chromosomal sex determination recently in a "review" journal
-- Current Biology, Current Opinion in Genes and Development,
Trends in Genetics, or Bioessays [most likely Bioessays]).
