I'm aware that the inability to interbreed is the standard definition
of two populations being of differing species, but more precisely,
is it:
a) can't physically mate due to differing genitals.
b) could, but don't mate due to differing sexual lures, rituals, etc.
c) can mate but produce no offspring.
d) can mate but produce sterile offspring, ie. horse+donkey=mule.
or is it several of the above?
