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 stages: Meiosis I and Meiosis II. Anaphase I is a part of Meiosis I.
During Anaphase I, homologous chromosomes, which are pairs of chromosomes containing the same genes but possibly different alleles, are separated.
These homologous chromosomes are pulled apart by spindle fibers and move towards opposite poles of the cell.
This separation reduces the chromosome number by half, which is a key feature of meiosis, distinguishing it from mitosis where sister chromatids separate.
