  The origin of seed perturbations in the Universe is studied within the
framework of a specific minisuperspace model. It is shown that the `creation'
of the Universe as a result of a quantum transition from a flat empty spacetime
would lead to a flat FLRW (Friedmann Lema\^\i tre Robertson-Walker) Universe
with weak inhomogeneous perturbations at large wavelengths. The power spectrum
of these perturbations is found to be scale invariant at horizon crossing
(i.e., the Harrison-Zeldovich spectrum). It is also recognised that the seed
perturbations generated in our model would be generically of the isocurvature
kind.
