Guida verificata passo dopo passo1
Recall the main stages of meiosis I and meiosis II, focusing on the behavior of chromosomes during each stage.
Understand that during Metaphase I, homologous chromosomes line up in pairs along the metaphase plate, but they have not yet separated.
Recognize that Anaphase I is the stage where homologous chromosomes are pulled apart by spindle fibers and move toward opposite poles of the cell.
Note that Anaphase II involves the separation of sister chromatids, not homologous chromosomes, and occurs in meiosis II.
Conclude that the correct stage for the separation of homologous chromosomes is Anaphase I.
