Here are the answers:

1. Produce gametes (sex cells)

2. A picture of an individual's chromosomes

3. It results in the exchange of genetic material between homologous chromosomes

4. Sex cells (gametes)

5. Interphase II (is NOT a phase of meiosis)

9. Two

10. True statements:
- The daughter cells are genetically different from the parent cell.
- The daughter cells have half the number of chromosomes as the parent cell.

11. Prophase I

12. By size and shape

13. The random lining up of homologous chromosomes during meiosis

14. 23

15. Anaphase I

16. It allows for adaptation and evolution

17. Spindle fibers

18. (Complete-sentence response)
- Crossing over is important because it creates new combinations of alleles by exchanging chromosome segments between homologous chromosomes, increasing genetic variation in offspring.
- Crossing over occurs during prophase I of meiosis, when homologous chromosomes pair up and form tetrads.

19. Meiosis II
