Guida verificata passo dopo passo1
Understand the process of meiosis, which consists of two consecutive divisions: Meiosis I and Meiosis II.
Recall that homologous chromosomes are pairs of chromosomes, one from each parent, that are similar in shape, size, and genetic content.
In Meiosis I, homologous chromosomes pair up during Prophase I and align at the metaphase plate during Metaphase I.
During Anaphase I, homologous chromosomes are separated and pulled to opposite poles of the cell. This is the key phase where homologous chromosomes separate.
In Meiosis II, sister chromatids separate during Anaphase II, but homologous chromosomes have already been separated in Anaphase I.
