Guida verificata passo dopo passo1
Recall the stages of meiosis and their key events: Prophase I, Metaphase I, Anaphase I, and Anaphase 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 crossing over occurs, but they do not separate yet.
In Metaphase I, homologous chromosome pairs align at the metaphase plate, preparing for separation.
In Anaphase I, homologous chromosomes (not sister chromatids) separate and move to opposite poles of the cell, which is the key event asked in the question.
