Parasynchronous

In synchronous division, all nuclei divide simultaneously. In parasynchronous division, mitosis is initiated in one location and then a wave of mitoses travels backwards down the hypha so that nuclei divide sequentially, almost as dominos fall in a line. In asynchronous division, neclei divide independently of neighbours, so the spatial and temporal pattern of mitosis is randomised.

However the cultures were parasynchronous, indicating the nitrous oxide may inhibit cell cycle traverse at points other than M.

The results of various studies suggest that even if the development of spermatogenic cells is not perfectly synchronized, the parasynchronous evolution of large groups is still remarkable.
