Synapsis is the process of pairing of homologous chromosomes along their lengths during meiosis. This pairing is essential for crossing over to occur, which allows for genetic recombination and variation in sexually reproducing organisms. Syngamy refers to the fusion of gametes during fertilization, prophase is the stage of cell division where the nuclear membrane breaks down and chromosomes condense, recombination is another term for crossing over, and the centromere is the region of a chromosome where spindle fibers attach during cell division.
