The distinguishing feature of prophase I of meiosis compared to prophase of mitosis is that **homologous chromosomes pair up**.
During prophase I of meiosis, homologous chromosomes undergo synapsis, forming pairs called tetrads, and can exchange genetic material through a process called crossing over. This pairing does not occur in mitosis, where individual chromosomes just condense and align separately without pairing.
