We consider the parallel transport through two quantum dots correlated by a semiconductor nanowire which may support a pair of Majorana bound states at the ends. In addition to transient dynamics, via modulating the quantum dot levels, we reveal a characteristic feature of symmetry and antisymmetry in the spectral density of cross-correlation mediated by Majorana fermion. We also find an intriguing behavior of the vanished cross-correlation when one of the dot levels is in resonance with the Majorana zero mode.
