The family replication problem is addressed in the context of the dual standard model. The breaking of a simple grand unified group to (Glow×H1×H2×H3)/Z35, and then further to Glow, produces a spectrum of stable monopoles that falls into three families, each of whose magnetic quantum numbers correspond to the electric charges on the fermions of the standard model. HereGlow = [SU(3)×SU(2)×U(1)]/Z6 is the symmetry group of the standard model above the weak scale, and Hi are simple Lie groups which each have aZ5 symmetry in common with Glow.
