Explanation:

Synapsis (pairing of homologous chromosomes) and crossing - over (exchange of genetic material between homologous chromosomes) are key events in meiosis. Interphase I is for cell growth and DNA replication. Prophase II and Metaphase I do not involve these specific events. Prophase I is when homologous chromosomes pair up (synapsis) and exchange genetic material (crossing - over).

Answer:

1. prophase I
