Genetics Course

What is cytokinesis?

What are the names for the two types of nuclear division?

Define mitosis. What does it make?


What is achieved in mitosis in terms of the genetic materials?



What word is used to describe a single set of chromosomes (n)?

What word is used to describe two sets of chromosomes (2n)?

In the spaces below draw the important structures that identify each phase paying particular attention where needed to chromosomes, centrosomes and both cell and nuclear membranes. Assume it is an animal cell starting with four chromsomes.
1. Interphase (late)

2. Prophase (late) or Prometaphase
3. Metaphase
4. Anaphase

5. Telophase

6. Cytokinesis (after mitosis)
showing early interphase

Define meiosis

What is achieved in meiosis (in terms of the genetic materials)? Why is meiosis necessary? Where does meiosis occur?





In the spaces below draw the important structures that identify each phase paying particular attention where needed to chromosomes, centrosomes and both cell and nuclear membranes. Show a cell that has a diploid number of 4 (2n = 4) and color or otherwise mark the M and P chromosomes and be sure you show proper tetrad/dyad patterns throughout. Assume it is an animal cell.

1. Metaphase I
 2. Anaphase I
1. Metaphase II
4. Anaphase

Summary of meiosis showing the ploidy and of the cell as it goes through meiosis I and meiosis II with the cytokinesis required to turn one diploid cell into four haploid cells. Assume a cell that has a diploid number of 4 (2n = 4)
