Understand that meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell.
Recall that meiosis consists of two stages: Meiosis I and Meiosis II, each with their own phases: Prophase, Metaphase, Anaphase, and Telophase.
Focus on Meiosis I, where homologous chromosomes pair up and exchange segments in a process called crossing over.
Identify that crossing over occurs during Prophase I of Meiosis I. This is when homologous chromosomes form tetrads and exchange genetic material, increasing genetic diversity.
Review the other phases of Meiosis I: Metaphase I (alignment of tetrads at the metaphase plate), Anaphase I (separation of homologous chromosomes), and Telophase I (completion of the first meiotic division), none of which involve crossing over.
