It is shown that if Goldstone particles are absent in a model of the strong and electroweak interactions based on the symmetry group G/sub L/xG/sub R/ (where G/sub L/,R = (SU(3)xSU(2)xU(1))/sub L/,R) with a renormalized Higgs potential, the necessary electric charges of the quarks (Q/sub u/ = 2/3, Q/sub d/ = -1/3, Q/sub ..nu../ = 0, Q/sub e/ = -1) are unambiguously fixed. The phenomenological aspects of such a model are considered. A mechanism is proposed for the creation of small Dirac neutrino masses, related to the hierarchy of ''left'' and ''right'' mass scales in broken G/sub L/xG/sub R/ symmetry, which (in contrast to standard approaches) does not require the introduction of additional superheavy neutrinos (the result that we obtain is me-italicapprox.(m/sup 2/(W/sup + -//sub L/)/ m/sup 2/(W/sup + -//sub R/))m/sub e/, where W/sup + -//sub L/ and W/sup + -//sub R/ are the charged weak bosons and m(W/sup + -//sub R/)>>m(W/sup + -//sub L/)).
