Questions to answer:
Meiosis
1. Explain how asexual reproduction is different from sexual reproduction.
2. Explain what happens during crossing over and when it occurs in meiosis.
3. How is metaphase I different from metaphase of mitosis?
4. Explain why sexual reproduction increases variation among offspring much more than asexual
reproduction does.
5. How many possible genetic variations can be produced during meiosis and sexual reproduction?
6. How is sexual reproduction related to gender determination in mammals?
7. If the progenitor cell of a gamete has 12 pairs of chromosomes during G1 of interphase, how many
chromosomes will the following cells have?
a. after S phase of interphase.
b. a daughter cell immediately following cytokinesis I of meiosis.
c. a daughter cell during anaphase II of meiosis.
d. a dauther cell immediately following cytokinesis II of meiosis.
Reproduction and Development
1. Explain what happens during each of the following phases of animal development:
a. fertilization
d. neurulation
b. cleavage
e. organogenesis
c. gastrulation
2. Diagram the structure of the amniotic egg, label each membrane and provide a brief description of
their functions.
3. What is the function of the placenta in eutherian mammals?
4. What would you expect would happen to gene expression in a cell as it develops and differentiates
in a developing organism?
5. Compare primary and secondary growth, and identify the tissue responsible for each.
6. Where is active xylem tissue found in a mature tree?
7. How is development in plants and animals similar? How does it differ?
Things you should make sure you understand:
(feel free to ask questions about them in class)
Meiosis
● The differences in sexual life cycles shown in plants, fungi, and animals.
● The relationship between homologous pairs of chromosomes.
● How meiosis evolved and why it bears a strong resemblance to mitosis.
● The major differences between mitosis and meiosis.
● The process of karyotyping and why/when it is used
Reproduction and Development
● How cells receive positional information during animal development.
● How cell fate is determined during animal development.
● How pattern formation in plants is established.
