There's a much simpler way to do this.  Just fiddle with the ratio of sperm
carrying the X and the Y chromosome.

Ah, David, it doesnot go that way.  The quarks are

u   c  t
d   s  b


Associated with this is the lepton, neutrino family.  I'll write this out,
due to the lack of symbols:

electron                        muon                          tau
electron neutrino           muon neutrino             tau neutrino

That's 12.  It can be 24 if you include the anti-particles.
