I haven't had time to look up the references you suggested, but will soon,
thank you very much-you are an invaluable resource. Why do you say "between
meisosis and ovulation"? Why not during meiosis itself? I am thinking of a
mechanism similar to what has been observed in yeast ERCs (don't know if that
segregation mechanism has been understood).

I guess one should do this with mice. By "other cells" I now mean
pre-ovulatory oocytes.
