WebbMitosis mitosis the homologous chromosomes. The difference is in a crossing over does not happen in mitosis, and that's because we're producing identical letters and crossing over adds variations, so only myosis 1 has crossing over so mechanics of crossing over which includes the formation of these tetrads. WebbIn anaphase 1, the centromere does not split. Instead, it remains as a whole.
