Abstract
Sufficient conditions for the relation tan beta similar or equal to m( t)/m(b) to hold in supersymmetric grand unified theories are formulate d. Essential ingredients are the SU(2)(R) gauge symmetry and a discret e matter parity. The applicability of our conditions is illustrated by specific examples. Implications for neutrino masses are discussed.
