Guida verificata passo dopo passo1
Recall the main stages of meiosis: Prophase I, Metaphase I, Anaphase I, Telophase I, followed by Meiosis II stages (Prophase II, Metaphase II, Anaphase II, Telophase II).
Understand that homologous chromosomes are pairs of chromosomes (one from each parent) that pair up during meiosis I.
During Prophase I, homologous chromosomes pair and exchange genetic material (crossing over), but they do not separate yet.
In Metaphase I, homologous chromosome pairs align at the metaphase plate, preparing for separation.
In Anaphase I, the homologous chromosomes are pulled apart to opposite poles of the cell, which is the stage where homologous chromosomes separate.
