Abstract
The problem of neutrino masses and mixing angles is analysed in a class of supersymmetric grand unified models withSO10 gauge symmetry and globalU2 flavour symmetry Adopting the seesaw mechanism for the generation of the neutrino masses one obtains a mass matrix for the lefthanded neutrinos which is directly related to the parameters of the charged sector while the unknown parameters of the righthanded Majorana mass matrix are inglobed in a single factor
