It is shown that, within the parton picture, weak (P-odd) effects increase with energy and momentum transfer. The presence of an effctive current with ΔS = 0 and 1 due to constituent interchange or annihilation is expected in the parton picture of hadron-hadron weak interactions. A typical value of P-odd effects, nucleon or hyperon polarization or asymmetry in quasi two-body reactions is about 10-4 at Elab ∼ 103 GeV and 10-3 in large angle (t ∼ s) scattering in the conventional current × current scheme of weak interactions. A principal possibility to clear up quark statistics is pointed out.
