  For Majorana or Dirac neutrinos, using Fritzsch-like texture 4 zero mass
matrices with parallel texture structures for the charged leptons and the Dirac
neutrino mass matrix (M_{\nu D}), detailed predictions for cases pertaining to
normal/inverted hierarchy as well as degenerate scenarios of neutrino masses
have been carried out. The inverted hierarchy as well as degenerate scenarios
seem to be ruled out at 3 \sigma C.L. for both Majorana and Dirac neutrinos.
For normal hierarchy, Jarlskog's rephasing invariant parameter J, the CP
violating Dirac-like phase \delta and the effective neutrino mass m_{ee} have
been calculated. For this case, lower limits of m_{\nu_1} and \theta_{13} would
have implications for the nature of neutrinos.
