During prophase I of meiosis, an important event is the process of synapsis, where homologous chromosomes pair up closely along their lengths to form tetrads. This pairing facilitates genetic recombination through crossing over, where segments of DNA are exchanged between non-sister chromatids, increasing genetic diversity in the resulting gametes. Additionally, the nuclear envelope begins to break down, and spindle fibers start to form, preparing the chromosomes for separation.
