  • Meiosis: Homologous Chromosome Pairing and Gamete Formation
    The pairing of homologous chromosomes before nuclear division happens in meiosis.

    Here's why:

    * Meiosis is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. This reduction in chromosome number is essential for sexual reproduction.

    * The pairing of homologous chromosomes, known as synapsis, occurs during prophase I of meiosis. This pairing allows for the exchange of genetic material between the chromosomes, a process called crossing over. This exchange increases genetic diversity in the offspring.

    * Mitosis, on the other hand, is a type of cell division that produces two daughter cells that are genetically identical to the parent cell. Homologous chromosomes do not pair up during mitosis.
