Verified step by step guidance1
Understand the process of meiosis, which consists of two consecutive divisions: meiosis I and meiosis II. Meiosis I is where homologous chromosomes are separated, and meiosis II is where sister chromatids are separated.
Recall the stages of meiosis I: Prophase I, Metaphase I, Anaphase I, and Telophase I. Each stage has distinct events that contribute to the separation of genetic material.
In Prophase I, homologous chromosomes pair up and exchange genetic material through crossing over, but they do not separate yet.
During Metaphase I, homologous chromosomes align at the metaphase plate, preparing for separation.
In Anaphase I, homologous chromosomes are pulled apart to opposite poles of the cell, marking the separation of homologous chromosomes. This is the key phase where the separation occurs.
