Meiosis: Questions
Matching: Match each statement with the correct phase.
_____
1. Chromatin is visible during this phase.
A. Interphase
_____
2. During this phase, chromosomes are first visible.
B. Prophase I
_____
3. Homologous chromosomes “stick” together in a process called synapsis.
C. Prometaphase I
_____
4. During this phase, replicated chromosomes become visible but they do not stick
together in pairs.
D. Metaphase I
_____
5. During this phase, homologous pairs of chromosomes move towards the center
of the spindle as the spindle forms.
E. Anaphase I
_____
6. During this phase, replicated chromosomes move towards the center of the
spindle as the spindle forms.
F. Telophase I
_____
7. At this point in time, homologous pairs of chromosomes are aligned in the
center of the cell.
G. Interkinesis
_____
8. At this point in time, replicated chromosomes (not pairs) are aligned in the
center of the cell.
H. Prophase II
_____
9. Homologous replicated chromosomes in a pair split into separate replicated
chromosomes and begin moving towards the poles during this phase.
I. Prometaphase II
_____
10. Replicated chromosomes split into separate chromosomes and begin moving
towards the poles during this phase.
J. Metaphase II
_____
11. Replicated chromosomes finish moving towards the poles in this phase.
K. Anaphase II
_____
12. Chromosomes (not replicated) finish moving towards the poles in this phase.
L. Telophase II
_____
13. Scientists use this word to refer to a “pause” in between meiosis I and meiosis
II. During this phase, centrosomes replicate but chromosomes do not.
M. Cytokinesis
_____
14. In this event, two cells split into the final four daughter cells.
N. Gametes
_____
15. These are the final products of meiosis.

Answer these questions in full sentences.
16. Why is it important for DNA to replicate during interphase, before meiosis? Does it replicate between meiosis I
and meiosis II?

18. What would happen if one of the chromosomes in a homologous pair failed to separate from its homologue at
the end of metaphase I? What would the final daughter cells look like?

19. What would happen if one of the replicated chromosomes in one of the two intermediate daughter cells failed to
split at the end of metaphase II? What would the final daughter cells look like?

20. How many chromosomes does the mother cell have in your diagram? How many chromosomes does one final
daughter cell have in your diagram? Why is this important? How are the mother cell and the daughter cells
different?
