Abstract
One-loop renormalization group equations for the quark mixing elements | V ij | and for the ratios h i h j of the eigenvalues of the Yukawa coupling matrices are derived in analytic form for a large class of theories and solved in the presence of large third generation Yukawa couplings. Comparison of scale dependence of the elements | V ij | and of the ratios h i h j is also given. The possible relevance of the evolution effects for understanding the pattern of quark masses and mixing is discussed.
