In the present paper, we have studied that the implication of a large value
of the effective Majorana neutrino mass in case of neutrino mass matrices
having either two equal elements and one zero element (popularly known as
hybrid texture) or two equal cofactors and one zero minor (popularly known as
inverse hybrid texture) in the flavor basis. In each of these cases, four out
of sixty phenomenologically possible patterns predict near maximal atmospheric
neutrino mixing angle in the limit of large effective Majorana neutrino mass.
This feature remains irrespective of the experimental data on solar and reactor
mixing angles. In addition, we have also performed the comparative study of all
the viable cases of hybrid and inverse hybrid textures at 3Ο CL
