Re: arilbred chromosome mysteries revealed (was: OGB+ in NY)


tom, sharon - after a few days rest and a day off from work, i have read and
re-read your emails and think i have sort of digested some of it -

has much of this type of hybridizing been done?  if i understood all this,
there can still be different chromosome numbers depending on what goes into
the OG part, but if its half O (10x2) and half G (11x2) always, then you'd
usually get the same number of chromosomes so they would be interfertile,
supposedly, right?  but i guess OG's are not necessarily or even usually?
 half and half.

are there lots of tetraploid TB x tet. aril crosses around?

what is an asi yearbook?  for that matter, what is asi?
