TABLE COMPARING MITOSIS AND MEIOSIS
MITOSIS
MEIOSIS
Number of divisions?
Number of daughter cells
produced?
Resulting daughter cells diploid
or haploid?
Purpose?
What type of cells undergo?
Cell Division Phase–use pictures and/or words to describe the major events in each.
Compare and contrast.
Prophase 1
Metaphase 1
Anaphase 1
Telophase 1
Prophase 2
Metaphase 2
Anaphase 2
Telophase 2
NAME:
PANTHER ID:
Name That Ploidy!
Each of these circles represents a nucleus and the lines are chromosomes. Lines of similar shape and color are homologous. For
each nucleus, label with the equation describing the ploidy.
In-Class Activity: Meiosis
Name:
Group members names:
Congratulations, you are going to create life:
1. You are beginning with a pre-gametic (somatic) nucleus with 4 chromosomes (2
homologous pair) cell. Draw it here. Differentiate between homologous chromosomes by
making each pair different in shape or color from the other pair. Then, label each
homolog with a letter. Label one member of each pair with a capital letter, and the other
with a lowercase letter. MAKE SURE YOU KNOW WHAT YOU ARE DRAWING
BEFORE MOVING ON!!!!!
What ploidy is this nucleus (haploid or diploid)? Write the equation:
2. This cell will now undergo Meiosis I and II to create gametes (egg or sperm). Draw what
this cell will look like at METAPHASE and ANAPHASE of Meiosis I
Metaphase I
Anaphase I
3. Draw the 4 daughter gametes (representing either egg or sperm) that would result from
meiosis I and II of the parent cell. What is the ploidy of the resulting daughter cells?
Write the word and the equation. Please check with your LA before continuing.
Super important.
4. Your partner should be doing the same thing. Put their resulting gametes below:
5. Now it is time for unprotected sex. Please take each gamete and combine it with all four
of your partner’s gametes until all combinations are done. This will result in 4×4
combinations.
Example: Ab x ab = Aabb

_____ x _____ = _____
6. What is the ploidy of the resulting embryonic cells? Pick one of the 16 and draw it:
7. What Mendelian principle is demonstrated by creation of all these gametes?
8. Notice many of the 16 are repeated. Count and report the number of unique
combinations.
