Understand that meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of gametes or spores.
Recall that meiosis consists of two consecutive divisions: Meiosis I and Meiosis II. Each division has several phases: Prophase, Metaphase, Anaphase, and Telophase.
Focus on Meiosis I, where homologous chromosomes (each consisting of two sister chromatids) pair up and then separate.
During Anaphase I, the homologous pairs of chromosomes are pulled apart by the spindle fibers towards opposite poles of the cell. This is the key event that distinguishes Anaphase I from other phases.
Recognize that in Anaphase I, unlike in mitosis or Meiosis II, the sister chromatids remain together, and it is the homologous chromosomes that are separated.
