Answer 1

Here are the answers to your questions:

1. What is the primary purpose of meiosis?

   • Produce gametes (sex cells)

2. What is a karyotype?

   • A picture of an individual's chromosomes

3. Which of the statements below about crossing over is correct?

   • It results in the exchange of genetic material between homologous chromosomes

4. Which of the following types of cells are haploid?

   • Sex cells (gametes)

5. Using the karyotype below, at which chromosome pair can we identify a genetic disorder?

   • Chromosome pair 21 (This is typically associated with Down syndrome or Trisomy 21.)

6. Place the following phases of Meiosis I in chronological order: (You will need to provide the specific phases to arrange them.)

7. How is genetic variation introduced during meiosis? Choose all that apply.

   • Through independent assortment
   • Through crossing over

8. Which of the following is NOT a phase of meiosis?

   • Interphase II

9. How many rounds of division occur in meiosis?

   • Two

10. Which of the following are true statements when comparing the parent cell with the daughter cells produced in meiosis?

    • The daughter cells have half the number of chromosomes as the parent cell
    • The daughter cells are genetically different from the parent cell.

11. During which phase of meiosis does crossing-over occur?

    • Prophase I

12. In a karyotype, how are chromosomes arranged?

    • By size and shape

13. What is independent assortment?

    • The random lining up of homologous chromosomes during meiosis

14. If the parent cell contains 46 chromosomes, how many chromosomes will each daughter cell have after meiosis?

    • 23

15. During meiosis, when do homologous chromosomes separate?

    • Anaphase I

16. What is the significance of genetic variation produced by meiosis?

    • It allows for adaptation and evolution

17. Which structure is responsible for moving chromosomes during meiosis?

    • Spindle fibers

18. Please respond to the following questions in complete sentences. Why is crossing over such an important event in meiosis? During which phase of meiosis does crossing over occur?

    • Crossing over is an important event in meiosis because it increases genetic diversity among gametes. This process allows for the exchange of genetic material between homologous chromosomes, resulting in new combinations of alleles. Crossing over occurs during Prophase I of meiosis.

19. What part of meiosis is most similar to mitosis?

    • Meiosis II
