We present a thorough analysis of U(1) generators in all of the nine possible symmetry-breaking patterns that reduce SU(7) down to SU/sub c/(3) x SU(2) x U(1). There is one allowed representation that contains three generations of leptons and at least two generations of quarks, and satisfies anomaly freedom, reality under SU/sub c/(3) and U/sub e/m(1), and complexity under SU/sub c/(3) x SU(2) x U(1). In addition, three other representations, two having only one and two of the three lepton-quark generations complex with respect to SU/sub c/(3) x SU(2) x U(1), and the other having fractionally charged color singlets in pairs embedded in the fundamental representation (7), are also analyzed for completeness.
