Verified step by step guidance1
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.
Recognize that meiosis consists of two stages: Meiosis I and Meiosis II, each with its own phases: Prophase, Metaphase, Anaphase, and Telophase.
Identify that crossing over is a process where homologous chromosomes exchange genetic material to increase genetic diversity.
Recall that crossing over occurs during Prophase I of Meiosis I, when homologous chromosomes pair up and exchange segments.
Note that during Prophase I, the synapsis of homologous chromosomes forms a structure called a tetrad, facilitating the crossing over process.
