  A comprehensive review of several aspects of fermion mixing phenomenon and
texture specific mass matrices have been presented. Regarding fermion mixings,
implications of unitarity and certain new developments for the CKM paradigm
have been discussed. In the leptonic sector, the question of possibility of CP
violation has been discussed in detail from the unitarity triangle perspective.
In the case of texture specific mass matrices, the issues of viability of
Fritzsch-like as well as non Fritzsch-like mass matrices have been detailed for
both the quark and leptonic sectors. The relationship of textures, naturalness
and weak basis rotations has also been looked into. The issue of the
compatibility of texture specific mass matrices with the SO(10) based GUT mass
matrices has also been discussed.
