    What is meiosis?

    A process that reduces chromosome number by half to form gametes.

    How do diploid and haploid cells differ?

    Diploid cells have two sets of chromosomes, while haploid cells have one.

    What happens during crossing-over?

    Homologous chromosomes exchange DNA segments, increasing genetic diversity.

    What are sister chromatids?

    Replicated chromosomes joined at the centromere.

    What is the result of meiosis II?

    Four haploid daughter cells are produced.

    What occurs in metaphase I of meiosis?

    Tetrads align at the metaphase plate.

    What is independent assortment?

    Random distribution of maternal and paternal chromosomes during gamete formation.

    How does meiosis contribute to genetic variation?

    Through crossing-over and independent assortment.

    What is the role of homologous chromosomes in meiosis?

    They pair up and separate to ensure proper chromosome number in gametes.

    What happens during anaphase I?

    Homologous chromosomes are pulled to opposite ends of the cell.

    What is the significance of the S phase in interphase?

    Chromosomes are duplicated before meiosis begins.

    What distinguishes meiosis from mitosis?

    Meiosis involves two rounds of division and results in haploid cells.

    What is a diploid cell?

    A cell containing two complete sets of chromosomes.

    What occurs during telophase II?

    Nuclear membranes form around four haploid daughter cells.

    What is a tetrad?

    A structure formed by the pairing of homologous chromosomes during meiosis.
