  The relations ${ {|V_{ub}|} \over {|V_{cb}|} } = \sqrt{ { m_u \over m_c } }$
and ${ {|V_{td}|} \over {|V_{ts}|} } = \sqrt{ { m_d \over m_s } }$ are
significant successes of some specific models for quark masses. We show that
these relations are more general, resulting from a much wider class of models.
Consequences of these predictions for CP violating asymmetries in neutral B
meson decays are discussed.
