3. 100 200 400 300 400 Meiosis Sexual vs. Asexual Reproduction Haploid vs. Diploid Misc. 300 200 400 200 100 500 100

4. Row 1, Col 1 What are all the stages of Meiosis? Meiosis I: Prophase I, Metaphase I, Anaphase I, Telophase and Cytokinesis I Meiosis II: Prophase II, Metaphase II, Anaphase II, Telophase and Cytokinesis II

5. Row 1, Column2 Define: Sexual Reproduction Reproduction in which gametes from a male and female create genetically unique offspring.

6. Row 1, Column 3 How many chromosomes do you have? Is it haploid or Diploid? 46 chromosomes & Diploid (23 from mom or 23 from dad)

7. Row 1, Column 4 Define: gamete A haploid reproductive cell that unites with another haploid reproductive cell. For example: sperm and egg cells.

8. Row 2, Column 1 What are the results of Meiosis? Haploid unique sperm or egg cells. One cell divides twice into 4 daughter cells.

9. Row 2, Column 2 Define: Asexual Reproduction Reproduction that does not involve the union of gametes and in which a single parent produces offspring that are genetically identical to the parent (clones).

10. Row 2, Column 3 Are gametes haploid or diploid? Gametes (sperm or egg cells) are: haploid (23 chromosomes)

11. Row 2, Column 4 Contrast Mitosis and Meiosis Mitosis produces two diploid cells Meiosis produces four haploid cells (gametes).

12. Row 3, Column 1 Define: homologous chromosome Homologous chromosomes are the same size, shape or structure, and genes.

13. Row 3, Column 2 Explain how you know if humans reproduce sexually or asexually Sexual reproduction: Humans through meiosis make gametes (sperm or egg cells) with unique genetic information that combine during fertilization.

14. Row 3, Column 3 During what stage do cells become haploid during meiosis? At the end of Meiosis II the cells are haploid (23 chromosomes)

15. Row 3, Column 4 What is crossing over and when does it occur? The exchange of genetic material between homologous chromosomes during meiosis (Prophase I)

16. Row 4, Column 1 What is the difference between Metaphase I and Metaphase II? Metaphase I: Homologous chromosomes line up on the Metaphase plate Metaphase II: Single Chromosome lines up on the metaphase plate

17. Row 4, Column 2 If you cut a starfish in half, both halves grow into a starfish. What kind of reproduction would this be? Sexual, Asexual or Both? Asexual because both new starfish would be clones (genetically identical).

18. Row 4, Column 3 How often are diploid cells and haploid cells made in males and females? New diploid cells are made through mitosis all the time for males and females for growth, repair and replacement. New haploid cells are made all the time in males (sperm). For females, eggs are made before puberty only.

19. Row 4, Column 4 When do homologous chromosomes get separated? Anaphase I

20. Row 5, Column 1 Compare and contrast Anaphase I and Anaphase II of Meiosis Anaphase I: Homologous chromosomes separate apart. Anaphase II: Sister chromatids separate apart.

21. Row 5, Column 2 Compare and contrast spermatogenesis and oogenesis. Spermatogenesis: male gamete formation. Diploid cell divides through meiosis to form 4 haploid cells. Oogenesis: Formation of egg (or ova). Diploid cell divides via meiosis into one egg cell and three nonfunctional polar bodies.

22. Row 5, Column 3 A chimpanzee has 48 chromosomes when it is (Haploid or Diploid). It has_____ (pick a #) chromosomes after meiosis when it is (Haploid or Diploid). 48 is diploid; it will have 24 chromosomes when it is haploid after meiosis.

23. Row 5, Column 4 When does the DNA replicate for Meiosis? Interphase just like Mitosis
