Introduction to Meiosis
The following tutorials can be completed using the on-line activities and your
text. Go to the Bio 12 Animations section of my website. Selection the Horton
Animation Folder in the header. Upon entering your username and password
and then locate the Cell Division Section and click on Enter. Select Meiosis
for the first part and Meiosis and Variation for the second part of the activity.
Meiosis
1. What are gametes?
2. What is the difference between the terms diploid and haploid?
3. What key step occurs in interphase prior to cell division?
4. What are homologous chromosomes?
5. What is synapsis?
6. What process occurs between homologous chromosomes during
Prophase I?
7. What disappears during Prophase I?
8. What happens to the homologous pairs during Metaphase I?
9. What separates during Anaphase I?
10. Are the cells in Telophase I diploid or haploid?
11. What separates during Anaphase II?
12. How many cells are produced in Telophase II?
13. What are the differences between Prophase I and Prophase II?
14. What are the differences between Metaphase I and Metaphase II?
15. What are the differences between Anaphase I and Anaphase II?
Meiosis and Variation
1. Identify three ways that genetic variation can occur.
2. Briefly explain how the three processes promote variation?
The Meiotic Process
The pictures on the following page will give you an excellent picture of the
process. Please use this in your studies. There are also other animations and
tutorials found on the Biology 12 Animations page of the website.
