Understand the term 'reductive division': it refers to a type of cell division where the chromosome number is halved, reducing the diploid number (2n) to the haploid number (n).
Recall the stages of cell division: Mitosis results in two identical diploid daughter cells, so it does not reduce chromosome number.
Consider Meiosis II: it resembles mitosis and separates sister chromatids but does not reduce chromosome number further; the cells remain haploid.
Analyze Meiosis I: homologous chromosomes are separated, which halves the chromosome number from diploid to haploid, making it a reductive division.
Confirm that Cytokinesis is the physical division of the cytoplasm and does not affect chromosome number, so it is not a reductive division.
