Obtaining a unified description of the quasi-degenerate neutrino mass spectrum together with the hierarchical charged fermions is a challenging task. In this talk, we discuss two distinct possible scenarios leading to such spectra in the supersymmetric SO(10) grand unified framework. Consistency of both scenarios is demonstrated through detailed fits to fermion masses and mixing angles, all of which can be explained with reasonable accuracy in a model with the most general Yukawa sector of SO(10). The origin of large neutrino mixing angles is linked to neutrino mass degeneracy in both the scenarios.
