Phenomenological relations for quark and neutrino mixing angles

The recent experimental data on mixing angles for quarks and neutrino have been discussed. Quarks mixing angles are calculated in the phenomenological approach of Fritzsch-Scadron-Delbourgo-Rupp (FSDR approach) using mass values of light and heavy constituent quarks. The neutrino mixing angles have been calculated with the high degree of precision with the help of the hypothesis of quarks and neutrino mixing angles complementarity, the results obtained do not contradict with the present experimental data.
