Starting with the unification hypothesis of mixings of quarks and leptons and small quark-like mixings at the see-saw scale, we find that two large mixings for νe —νx03BC; andvμ—vτ at the weak scale are obtained as a result of renormalization group evolution and radiative magnification if the three neutrinos are quasi degenerate in masses and possess the same CP parity. We also find thatUe3 remains small and well within the CHOOZ-Palo Verde bound since the correspondingVub for CKM mixing is very small. Several testable pedictions are pointed out.
