How does meiotic cell division produce genetically variable, haploid cells?
What will be an ideal response?
Meiotic cell division (meiosis followed by cytokinesis) separates homologous chromosomes and produces haploid cells with only one homologue from each pair. During interphase before meiosis, chromosomes are duplicated. The cell then undergoes two specialized divisions-meiosis I and meiosis II-to produce four haploid daughter cells.
