That's a real tough one.  From the minimal literature, it appears to be
possible with meiotic chromosomes, rather than mitotic ones.  The
trick, then, is to get the little buggers to sporulate.  I tried a few
protocols, but either didn't get it to work, or it did, but I just
didn't recognize it under the scope. Don't have the sources handy...I'm
at home, and they're in the lab.  I have since moved on to other
projects.  I'll take a look tomorrow, and see if I can put my hands on
the sources.
