Unit 4 Exam Review Guide
Name __________________________________________ Hour _____
Exam Format:
#11 MC- 3b Inheritable genetic variations may result from new genetic combinations through meiosis (100 pts)
#9 MC- : 1c I can illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex
organisms.
1. What is asexual reproduction and sexual reproduction?
2. What type of reproduction is binary fission and how does it occur?
3. Complete the following table comparing the advantages and disadvantages of the types of reproduction.
Asexual Reproduction
Sexual Reproduction
Advantages
Disadvantages
4.
Place the following in order:
5. Why is sexual reproduction considered preferable to asexual reproduction ?
6.
How many chromosomes are in the cells that are produced during Meiosis in humans?
7. Two gametes containing 10 chromosomes fuse during fertilization. How many chromosomes will the zygote
contain?
8. A particular species has 12 chromosomes. Two adult organisms go through the process of Meiosis, producing
gametes. When these two gametes combine, how many chromosomes will the resulting zygote contain?
9. A cell undergoing meiosis produces a daughter cell that experiences one nondisjunction event.
If the number of chromosomes in a normal diploid cell is 30, how many chromosomes are present in this
daughter cell?
10. Sperm cells are the only cells in the human male body that have what?
11. What are the haploid and diploid numbers for humans?
13. A sperm cell is (diploid, haploid)
14. Somatic (body) cell is (diploid, haploid)
15. Skin cells would be (diploid, haploid)
16. Mitosis results in two ________ cells, while meiosis results in _______ haploid cells.
17. A single cell, containing 18 chromosomes is extracted from an unknown organism. This cell undergoes Mitosis twice.
How many chromosomes will the new cells contain?
18. If a bacteria cell has 30 chromosomes, we can infer that the parent cell had how many chromosomes?
19. At what point in Meiosis does the cell go from being diploid to being haploid?
20. True or False:
_______Plants asexually reproduce because flowers contain male and female anatomy.
_______Sexual reproduction must involve the creation of gametes.
_______Some prokaryotic cells use sexual reproduction to reproduce.
_______Binary Fission is one way to create sex cells in eukaryotic organisms.
21. Describe what happens in the four phases of mitosis (PMAT).
a. prophase
b. metaphase
c.
anaphase
d. telophase
22.Draw what the daughter cells of the following parent cell would look like if it were a somatic (body) cell undergoing
mitosis or meiosis.
Mitosis
23. Identify the following phases of the cell cycle and mitosis.
Meiosis
