Explanation:
Detailed explanation-1: -Synapsis is the pairing of two homologous chromosomes that occurs during meiosis.
Detailed explanation-2: -Homologous chromosomes pair up and exchange fragments in the process of crossing over. Metaphase I: Homologue pairs line up at the metaphase plate. Anaphase I: Homologues separate to opposite ends of the cell. Sister chromatids stay together.
Detailed explanation-3: -Meiosis I is a unique cell division that occurs only in germ cells; meiosis II is similar to a mitotic division. Before germ cells enter meiosis, they are generally diploid, meaning that they have two homologous copies of each chromosome.
