        But this won't get you an exact ratio!  Note that the two
kinds of sperm do behave differently.  If this is the system used
on Stratos--it's not clear how much the Founders changed things.

        So there is a correspondence, where u and d go with electrons,
c and s go with muons, and t and b go with taus?  Sorry, I must have
remembered it wrong.
