  We present a model where all fermions are contained in a single irreducible
representation of an SU(19) gauge symmetry group. If there is only one scalar
field, Yukawa interactions are controlled by a single number rather than by one
or more $3\times3$ matrices of couplings. The low-energy concept of flavor
emerges entirely from the scalar-sector parameters; more specifically, entries
of the Standard Model Yukawa matrices are controlled by several vacuum
expectation values.
