Meiosis Drawing Requirements
Draw the stages of meiosis as modeled on page 142 and 143. Each object listed below is worth 1 point.
If I can see it in the picture, it is positioned correctly and done neatly then you get the points.
Side 1- Meiosis 1:
1. Prophase 1- 4 points LABEL THE FOLLOWING: This is the only picture that needs labels!
a. Fading nuclear membrane
b. Chromosomes showing crossing over
c. Spindle fibers
d. Centrosome (centrioles)
You do not need to label anything in these drawings.
However, I must see the following when I look at the pictures that you drew.
2. Metaphase 1- 4 points
a. Chromosomes
b. Spindle fibers
c. Centrosome (centrioles)
d. Crossing over has occurred
3. Anaphase 1- 4 points
a. Chromosomes
b. Centromere is still intact
c. Spindle fibers
d. Centrosome (centrioles)
4. Telophase 1 and cytokinesis- 4 points
a. 2 Nuclear membranes have formed
b. Chromosomes
c. Spindle fibers
d. Centrosome (centrioles)
Side 2- Meiosis 2:
5. Prophase 2- 4 points
a. Deteriorating nuclear membranes
b. Chromosomes
c. Spindle fibers
d. Centrosome (centrioles)
6. Metaphase 2- 4 points
a. Chromosomes
b. Spindle fibers
c. Centrosome (centrioles)
d. Crossing over has occurred
7. Anaphase 2- 4 points
a. Chromosomes
b. Centromere is no longer intact
c. Spindle fibers
d. Centrosome (centrioles)
8. Telophase 2 and cytokinesis- 4 points
a. 4 Nuclear membranes have formed
b. Chromosomes
c. Spindle fibers
d. Centrosome (centrioles)
Neatness- 10 points
9. Neatness counts. I want you to put time and effort into these drawings.
10. I will judge your drawing on a scale from 0-10 and assign it points accordingly.
