Dear Sarah,
 
I'm afraid you are a bit wrong.
I don't know for sure, but I have never heard of Eubacteria mating and
producing offspring.
Furthermore, Tom Eichhorst wrote about two different species of snakes
(even in different genera)  who produced fertile offspring.
And what about self fertilising plants (Taraxum officinale e.g.).
There are also some fresh water snails where males are extremely rare: less
then one per 10,000. Poor guy if that one was to fertilise al those
females.
 
Gijs
