An alternative possibility for the nuclear origin of anomalous abundance in Ap and Am stars is suggested. In the early period of expansion of supernova shells, the Rayleigh-Taylor instability, plasma instabilities or, at a later period, some instability accompanying dust formation would occur. These instabilities might cause more or less pronounced density and composition inhomogeneities, and chemically inhomogeneous clumps or knots of clouds might appear in the expanding shells. It is conceivable that in the expanding supernova shells there are chemically inhomogeneous clumps embedded in and coexpanding with the chemically homogeneous background gas. The presented hypothesis accounts well for the gross feature of abundance curves on the Ap and Am stars. However, it cannot always explain the details of the curves.
