Answers Graded A+
What is the function of the chiasma in meiosis?
✔✔ The chiasma is the point where homologous chromosomes exchange genetic material during
crossing over.
What occurs during prophase I of meiosis that does not occur in mitosis?
✔✔ During prophase I, homologous chromosomes pair up and form tetrads, which does not
happen in mitosis.
How is genetic variation achieved through meiosis?
✔✔ Genetic variation is achieved through crossing over, independent assortment, and the
random combination of gametes.
What is the difference in the chromosome number of cells at the end of meiosis I and meiosis II?
✔✔ At the end of meiosis I, cells have half the chromosome number of the original cell, and at
the end of meiosis II, the chromosome number is still halved but now in single chromatids.

, What happens during metaphase I of meiosis?
✔✔ During metaphase I, tetrads line up along the metaphase plate, with each homologous
chromosome facing opposite poles.
How do meiosis and sexual reproduction work together to create genetic diversity?
✔✔ Meiosis creates genetically diverse gametes, and sexual reproduction combines these
gametes, further enhancing genetic diversity in offspring.
What role does meiosis play in maintaining the stability of chromosome number across
generations?
✔✔ Meiosis ensures that gametes have half the chromosome number, so when two gametes fuse
during fertilization, the chromosome number is restored to its original state.
How does meiosis contribute to the concept of inheritance?
✔✔ Meiosis distributes genetic material into gametes in a way that contributes to the inheritance
of traits from parents to offspring.
What is the role of the centrosome during meiosis?
