摘要：

We classify the different neutrino-mass patterns arising in string-inspired GUT and supersymmetric GUT models based on the flipped SU(5)XU(1) and the SU(4)XO(4) gauge groups. Phenomenologically interesting spectra are obtained through the interplay of the two seesaw mechanisms present, with typical neutrino masses approximately 10(-3) eV in the supersymmetric GUT models and of order 0.1-10 keV in the ordinary GUTs.
