Understand that meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell.
Recall that meiosis consists of two stages: Meiosis I and Meiosis II. Anaphase I is a part of Meiosis I.
During Anaphase I, homologous chromosomes are separated. This is different from mitosis and Meiosis II, where sister chromatids are separated.
In Anaphase I, the homologous chromosomes, each consisting of two sister chromatids, are pulled to opposite poles of the cell by the spindle fibers.
This separation reduces the chromosome number by half, which is a key feature of meiosis, ensuring genetic diversity in the resulting gametes.
