Understand the process of meiosis, which consists of two main stages: Meiosis I and Meiosis II. Meiosis I separates homologous chromosomes, while Meiosis II separates sister chromatids.
Recall the role of spindle fibers during cell division. Spindle fibers attach to chromosomes and help move them to specific locations within the cell.
Review the phases of Meiosis I: Prophase I, Metaphase I, Anaphase I, and Telophase I. Focus on Anaphase I, where homologous chromosomes are pulled apart to opposite poles of the cell by spindle fibers.
Compare Anaphase I with Anaphase II. In Anaphase II, spindle fibers separate sister chromatids rather than homologous chromosomes.
Identify the correct phase where spindle fibers move homologous chromosomes to opposite poles of the cell. Based on the description, this occurs during Anaphase I.
