Neil, There are several ways to do this, but I would say the most accurate
way is to use a microscope and count chromosomes. For TBs,  if there is a
total of 24c then it is presumed diploid, if it has a count of 48c then it
is presumed tetraploid. Another way is using a petrie dish but I have never
done this, but may Harald Mathes might know. He is also on this web site.
