  The relations between matrix elements of different P- and T-odd weak
interactions are derived.
  We demonstrate that similar relations hold for parity nonconserving (PNC)
transition amplitudes and electron electric dipole moments (EDM) of atoms and
molecules. This allows to express P- and T-odd effects in many-electron systems
caused by different symmetry-breaking mechanisms via each other using simple
analytical formulas. We use these relations for the interpretation of the
anapole moment measurements in cesium and thallium and for the analysis of the
relative contributions of the scalar-pseudoscalar CP-odd weak interaction and
electron EDM to the EDM of Cs, Tl, Fr and other atoms and many polar molecules
(YbF, PbO, ThO, etc.). Model-independent limits on electron EDM and the
parameter of the scalar-pseudoscalar CP-odd interaction are found from the
analysis of the EDM measurements for Tl and YbF.
