Abstract
Evolution of the genus density is calculated from Gaussian initial con ditions using the Zeldovich approximation. A new approach is introduce d that formulates the desired quantity in a rotationally invariant man ner. It is shown that the normalized genus density does not depend on the initial spectral shape but is a function of the fluctuation amplit ude only.
