2. This type of cell division results in identical daughter cells.

3. This phase is categorized by chromosomes aligning at the center of the cell.

4. This phase is categorized by the separation of sister chromatids.

5. This phase is categorized by the reformation of daughter nuclei.

6. This phase is categorized by the condensing of chromatin.

7. Meiosis results in this number of daughter cells.

8. Meiosis is the process of producing this kind of cell.

9. Meiosis involves this number of cell divisions.

10. Meiosis in humans results in daughter cells with this chromosome number.

11. Meiosis only occurs in organisms that participate in what form of reproduction?

12. This step in the cell cycle describes the physical separation of two daughter cells.

13. This sub-phase of the cell cycle repairs errors in DNA replication.

14. This sub-phase of the cell cycle duplicates the cell’s contents except for the chromatin.

15. This is the longest phase of the cell cycle.

16. This disease is often the result of missing cell cycle regulation.

17. This type of reproduction requires genetic contributions from two organisms of opposite sexes.

18. This type of reproduction results in genetically identical offspring.

19. This event in sexual reproduction restores chromosome number in the zygote.

20. Describe one advantage to asexual reproduction.

21. Describe one advantage of sexual reproduction.

22. This structure is how DNA is primarily stored.

23. These are formed during prophase. Remember, humans have 46 of them.

24. These structures separate from each other in anaphase.

25. This term describes chromosomes that are paired
This term describes chromosomes that are paired. One copy comes from Mom and one copy comes from Dad.

26. These proteins form octamers around which DNA is wound to form nucleosomes.

27. A change in a DNA sequence.

28. This type of reproduction produces offspring that are genetically unique.

29. The fusing of sperm and egg produces genetic variation because it happens ____.

30. This process of meiosis creates variation in daughter cells as sister chromatids swap DNA.

31. Describe how genetic variation can be advantageous to organisms.
