The nuclear envelope reassembles and begins to surround each new set of chromosomes. WebDuring meiosis, double-strand breaks occur in chromatids. The breaks are either repaired by the exchange of genetic material between homologous nonsister chromatids, which is the process known as crossing over (Figure 1A), or they are simply repaired without any crossing over (Figure 1B). number of voids in fcc
