We have independently measured the genus topology of the temperature fluctuations in the cosmic microwave background seen by the Wilkinson Microwave Anisotropy Probe ( WMAP ). A genus analysis of the WMAP data indicates consistency with Gaussian random‐phase initial conditions, as predicted by standard inflation.
