Cell Cycle: Meiosis
This is supplemental material to Lecture #11 that I provide to students taking my Cell Biology for Health Science, HCR 118 course.
You don't need to be enrolled in this class to access the materials here. Anyone taking, teaching or interested in biology may find this material useful and is welcome to use it.
This page includes or directs you to:
- a list of learning objectives
- review questions
- practice test questions
- a practice mitosis exercise
- animations of mitosis
- a PowerPoint lecture
- additional articles that support the lecture material
Lecture 11 Learning Objectives
o Make a list comparing and contrasting mitosis and meiosis. You do have some slides that make these comparisons. But after you’ve studied, see if you can make a list on your own, from memory.
o How many nuclear divisions occur in mitosis? Meiosis?
o What separates during meiosis I? What separates during meiosis II?
o What is independent assortment?
o What is crossing over?
o Know the phases of meiosis I and meiosis II.
o If a cell with 6 chromosomes divides to form gametes, how many chromosomes will the resulting gametes each have?
o What were the 3 things that we discussed which increase genetic diversity in sexually reproducing organisms?
o Other than fostering genetic diversity, what other advantage is there to sexual reproduction (I am looking for a Biology Answer. ‘Sex is fun’ is not the answer I am looking for here).
o In order to make sure that you understand what goes on during the phases of mitosis and meiosis, practice with paper models like we did in class, or draw it out. This will help you truly understand.

Meiosis Practice Worksheet
Click here for a Word document which you can use to diagram the stages of mitosis. This exercise will help you to make sure you understand what is happening to the chromosomes during each stage of nuclear division.
