Based on the hierarchy exhibited by quarks masses at low energies, we assume
that Yukawa couplings of up and down quarks are related by $Y_u\propto Y_d^2$
at grand unification scales. This ansatz gives rise to a symmetrical CKM matrix
at the grand unification (GU) scale. Using three specific models as
illustrative examples for the evolution down to low energies, we obtain the
entries and asymmetries of the CKM matrix which are in very good agreement with
their measured values. This indicates that the small asymmetry of the CKM
matrix at low energies may be the effect of the renormalization group evolution
only.
