Conservation of B: L and nonconservation of B are shown to follow simply from the weak isospin properties of quarks and leptons; namely that left-handed particles and right-handed antiparticles have weak isospin 1/2, that all other fermions are singlets, and that particles with half-integral isospin can only be created or annihilated in pairs.
