I'm confused ... again.  I could sit down with TWOI and try to muddle 
through the genetics chapter for the umpteenth time, but I doubt it 
would make any more sense to me now than it did the first couple dozen 
times I tried to absorb it.  What I really need is a "Chromosomes for 
Dummies" version of the same info.

I don't understand why beardless species seem to be able to interbreed 
successfully regardless of varying chromosome counts, while beardeds 
can not.  Sibtosa works, but attica X pumila doesn't?  I just don't 
get it.

Can anyone offer an idiot-proof explanation in 500 words or less, 
please?  ;-)
