When does a cells DNA replicate?
prophase
anaphase
interphase
telophase
- 12. Multiple Choice
What is an advantage of sexual over asexual reproduction?
Asexual reproduction provides greater genetic variation
Sexual reproduction provides greater genetic variation
Asexual reproduction provides identical offspring
Sexual reproduction provides identical offspring
- 13. Multiple Choice
Which statement best describes the end result of meiosis?
the production of a somatic diploid cell
the production of 4 diploid daughter cells
the production of 2 haploid daughter cells
the production of either a sperm or egg cell
- 14. Multiple Choice
A student notices dark X-shaped structures in a cell when looking under a microscope. What is most likely happening?
interphase
cytokinesis
mitosis
cell growth
- 15. Multiple Choice
Which best explains why DNA replication occurs within a cell?
So the daughter cells will have half the required genetic information
So the daughter cells will have three times the genetic information
So the daughter cells will have an identical set of genetic information
So the daughter cells will have different forms of the genetic information
- 16. Multiple Choice
Mitosis is the division of the
cell
nucleus
cytoplasm
centrioles
- 17. Multiple Choice
DNA replication must occur
before the nucleus divides
following cytokinesis
during mitosis
all of the above
- 18. Multiple Choice
During mitosis, the sister chromatids divide during
prophase
anaphase
telophase
metaphase
- 19. Multiple Choice
During mitosis, the sister chromatids line up at the cell's equator during
metaphase
prophase
anaphase
telophase
- 20. Multiple Choice
Meiosis occurs
in all sexually reproducing organisms
in all asexually reproducing organisms
only when eggs are fertilized
during cytokinesis
- 21. Multiple Choice
Pairs of homologous chromosomes line up at the cell's equator during which stage of meiosis?
Anaphase 1
Metaphase 1
Metaphase 2
Prophase 1
- 22. Multiple Choice
In meiosis, two successive divisions result in
the formation of 2 identical cells
four haploid cells
a zygote
identical haploid cells

- 26. Multiple Choice
Why would the process of crossing over be important?
Allows for genetic diversity
So genetic information is shared
for meiosis to be complete
all of the above
It is not important
- 27. Multiple Choice
In which phase would crossing over occur?
Prophase 1
Prophase 2
anaphase 1
telophase 2
- 28. Multiple Choice
What are homologous chromosomes?
Homologous chromosomes are the same size
Homologous chromosomes have the same gene locations (think of the pigeon activity)
One is inherited from mom
One is inherited from dad
All of the answers above
- 29. Multiple Choice
In humans, each gamete receives
23 pairs of chromosomes from each parent
one chromosome from each of the 23 pairs
46 chromosomes from each parent
23 homologous chromosomes from each parent.
- 30. Multiple Choice

Interphase
Metaphase
Anaphase
