    What is the role of meiosis in sexual reproduction?

    It creates genetic variation through reshuffling of genes.

    How does asexual reproduction differ from sexual reproduction?

    Asexual reproduction involves a single organism and only genetic mutations.

    What are gametes?

    Sex cells produced by germline cells.

    What happens during fertilization?

    Gametes fuse to form a zygote.

    How many chromosomes are in a human sperm or egg?

    Each has 23 chromosomes.

    What is the outcome of meiosis?

    Four genetically different haploid cells.

    What distinguishes meiosis from mitosis?

    Meiosis involves two rounds of division and creates variation.

    What occurs during crossing-over in meiosis?

    Homologous chromosomes exchange genetic material.

    What is independent assortment?

    Random distribution of homologous chromosomes during meiosis.

    What is the significance of the S phase in meiosis?

    DNA replication occurs before both meiosis and mitosis.

    What happens in Metaphase I of meiosis?

    Homologous chromosomes line up in pairs.

    What is the result of Anaphase I?

    Homologous chromosomes are separated.

    What occurs during Telophase I?

    Nuclei reform and cells separate into haploid cells.

    What is the difference between Metaphase I and Metaphase II?

    Metaphase I has paired homologous chromosomes; Metaphase II has single chromosomes.

    What is the final product of meiosis II?

    Four unique haploid cells are formed.

    What is the role of meiosis in sexual reproduction?

    It creates genetic variation through reshuffling genes.

    How does asexual reproduction differ from sexual reproduction?

    Asexual reproduction involves one organism and only genetic mutations.

    What are gametes?

    Sex cells produced by germline cells.

    What happens during fertilization?

    Gametes fuse to form a zygote.

    How many chromosomes are in a human sperm or egg?

    Each has 23 chromosomes.

    What is the outcome of meiosis?

    Four genetically different haploid cells.

    What distinguishes meiosis from mitosis?

    Meiosis involves two rounds of division and creates variation.

    What occurs during crossing-over in meiosis?

    Homologous chromosomes exchange genetic material.

    What is independent assortment?

    Random distribution of chromosomes during meiosis.

    What is the significance of the zygote?

    It develops into the next generation organism.

    What happens in Metaphase I of meiosis?

    Homologous chromosomes line up in pairs.

    What is the result of Anaphase I?

    Homologous chromosomes separate to opposite poles.

    What occurs during Meiosis II?

    Sister chromatids are separated into haploid cells.

    What is the difference between Metaphase I and Metaphase II?

    Metaphase I has homologous pairs; Metaphase II has single chromosomes.

    What is the role of interphase in meiosis?

    DNA is replicated before cell division begins.
