  I discuss the properties of the minimal supersymmetric extension of the
standard model, in the case in which there is a dynamical breakdown of the
electroweak symmetry induced by the formation of condensates of the third
generation of quarks and their supersymmetric partners. The top quark and Higgs
mass predictions derived within this scheme are essentially equivalent to those
ones obtained from the requirement of bottom-tau Yukawa coupling unification in
a supersymmetric grand unified scenario, if the compositeness scale is
identified with the grand unification scale. I give an explanation of this
interesting result, for which the relevance of the infrared quasi fixed point
on the top quark Yukawa coupling is emphasized.
