We present a class of Ansatze for the up and down quark mass matrices whichleads approximately to: |V_{us}| \sim \sqrt{m_d / m_s}, |V_{cb}| \sim m_s /m_b, and |V_{ub} / V_{cb}| \sim \sqrt{m_u / m_c}. Sizes of theKobayashi-Maskawa matrix elements are controlled solely by quark mass ratios.In particular, we introduce no other small parameter and our results do notrely on delicate cancellation.Comment: 10 Page
